Optionally scope to a specific subreddit. ## GET /v1/reddit/search **Search posts** Temporarily unavailable: Reddit has blocked third-party apps from its API, so this endpoint returns 503 `PLATFORM_DISABLED` until Reddit restores access. Reddit Ads is not affected. Search Reddit posts using a connected account. Optionally scope to a specific subreddit. ### Parameters - **accountId** (required) in query: No description - **subreddit** (optional) in query: No description - **q** (required) in query: No description - **restrict_sr** (optional) in query: No description - **sort** (optional) in query: No description - **limit** (optional) in query: No description - **after** (optional) in query: No description ### Responses #### 200: Search results **Response Body:** - **items** `array[RedditPost]`: - **after** `string,null`: No description - **before** `string,null`: No description #### 400: Invalid request **Response Body:** - **error** `string`: Human-readable error message. - **type** `string`: Error class for programmatic handling. - one of: invalid_request_error, authentication_error, permission_error, not_found, rate_limit_error, platform_error, api_error - **code** `string`: Stable machine-readable error code. - **param** `string`: The request field that caused the error, when applicable. - **docUrl** `string`: Documentation page for resolving the error, when one applies. - **platform** `string`: Upstream platform (e.g. meta, google, tiktok), present when type is platform_error. - **platformError** `object`: Raw error payload from the upstream platform, passed through verbatim so integrators can read provider-specific codes. For Meta this includes error_subcode, error_user_title, and error_user_msg. - **details** `object`: Additional structured context for the error (for example field-level validation errors). What it carries depends on the endpoint and platform. **Meta ads refusals.** The ones customers hit most come back with their own `code` instead of `platform_api_error`, the field to fix in `param`, and `details.fix` ({ label, url }) pointing at the Meta page that resolves it: - `ad_account_payment_required` - `ad_account_policy_not_accepted` - `meta_security_check_required` - `meta_action_blocked` - `whatsapp_number_not_linked` - `invalid_targeting` Meta's own error stays in the message and in `platformError`. **Private replies.** `privateReplyConsumed` appears on the private-reply endpoint's 400 when the comment's single reply is already spent. `privateReplyOutcome: "unknown"` appears on its 502 when Meta answered a server error and the reply may have been delivered. **Google quota 429.** On a Google Ads or YouTube Analytics 429, `quotaExhausted: true` marks the failure as Google's own quota, not a Zernio rate limit, so you can keep calling other platforms instead of backing off everywhere. When Google names the scope, `quotaScope` is also set: - `DEVELOPER`: the shared budget (the developer token for Google Ads, the Google Cloud project for YouTube Analytics). Every account on Zernio is affected and there is nothing to change on your side. - `ACCOUNT`: your own ad account (Google Ads only). A Meta 429 carries neither field. **Zernio Google Ads burst-limit 429.** Carries `budgetScope` instead, never `quotaExhausted`. These are Zernio's own limits, applied before the call reaches Google, and both clear within a minute. They are separate axes from `quotaScope`, not the same pool named twice. - `account`: the limit of 15 requests per minute per connected Google Ads account. - `user`: the ceiling of 120 requests per minute per Zernio user across all their Google Ads accounts. **Failed Meta ad create** (`POST /v1/ads/create`, `POST /v1/ads/boost`, `POST /v1/ads/ctwa`). Carries `stage` (where it failed), `adAccountId` (on which ad account) and `createdObjects` (every object this request had already created, with what cleanup did to it). - `left_behind` objects still exist on the ad account (Meta refused the delete, typically on a held account, or the delete hit a network error). Delete them yourself or reuse them. - `unconfirmedWrite` is set when Meta answered a create with a 5xx or dropped the connection and Zernio could not confirm whether the object exists. Check that parent before creating it again. **Ineligible ad account: 422 `ad_account_unusable`.** When Meta refuses a write because the ad account's status is ineligible to manage ads (Meta subcode 2490592 or 4841021, on the write itself or on a cleanup delete), any Meta ads write answers it. That covers create, boost, CTWA, campaign / ad set / ad updates and status changes. The message names the ad account when known, links Meta's fix (https://www.facebook.com/business/help/422289316306981), lists the objects left behind and ends with Meta's original error, which also stays verbatim in `platformError`. Meta often reports the first failure under an unrelated code (e.g. 1487194 on the creative), so branch on `code`, not on `platformError`. **Missing Advertise permission: 403 `insufficient_permissions`.** When the Facebook user behind the connection's token lacks the Advertise permission on the ad account, any Meta ads write answers it. Triggers: Meta subcode 2490585, 2490591 or 4841020 on the write, or a code 200 refusal such as 1487194 whose cleanup deletes Meta refused with 2490591 or 4841020. Meta may still accept the campaign and ad set and refuse only the ad. The message names the ad account, asks for the Advertise or Manage permission on it (or a token granted `ads_management`, by reconnecting) and lists the objects left behind. It ends with Meta's `error_user_title`, `error_user_msg` and subcode; the raw error stays in `platformError`. - **stage** `string`: Meta ad create failures only. The step that failed: - `media`: image/video download or upload. - `campaign` - `adset` - `creative` - `ad`: the ad POST itself, where Meta's code 31 / 3858385 hold and 100 / 1359188 payment rejections land. - `activation`: switching the created objects on. No longer returned: a refused switch to ACTIVE now answers 201 with an `activation_failed:` warning and the objects kept PAUSED. - `other`: a read or check before any write. - one of: media, campaign, adset, creative, ad, activation, other - **adAccountId** `string`: Meta ad create failures only. The ad account the request wrote to (`act_...`). - **createdObjects** `array[object]`: Meta ad create failures only. Every object this request created before failing, in creation order. Objects you referenced (an existing campaign, ad set, creative or video) are never listed and never deleted. - **type** `string`: No description - one of: campaign, adset, creative, ad, video, image - **id** `string`: Meta object id; for `image` the image hash. - **cleanup** `string`: `deleted`: Zernio deleted it. `left_behind`: cleanup could not delete it (Meta refused the delete, or the delete hit a network error), so it still exists. `kept`: deliberately not deleted (image hashes are shared by every upload of the same file). - one of: deleted, left_behind, kept - **unconfirmedWrite** `object`: Meta ad create failures only, when Meta answered a create with a 5xx or dropped the connection and the object could not be looked up. Zernio did not retry it. - **type** `string`: No description - one of: campaign, adset, creative, ad - **parentId** `string`: Where to look for it: the ad set for an ad, the campaign for an ad set, the ad account otherwise. - **quotaExhausted** `boolean`: Google Ads and YouTube Analytics 429 only. True when the upstream Google quota is spent rather than a Zernio limit. - **quotaScope** `string`: Google Ads and YouTube Analytics 429 only, when the scope is known. DEVELOPER is the shared budget (the developer token for Google Ads, the Google Cloud project for YouTube Analytics); ACCOUNT is your ad account (Google Ads only). - one of: DEVELOPER, ACCOUNT - **budgetScope** `string`: Zernio Google Ads burst-limit 429 only (never set alongside `quotaExhausted`). `account` is the limit of 15 requests per minute per connected Google Ads account; `user` is the ceiling of 120 requests per minute per Zernio user across all their Google Ads accounts. Both clear within a minute. - one of: account, user #### 401: Missing or invalid API key. `code` is `missing_credentials` when no Authorization header was sent and `invalid_credentials` when the key is unknown, revoked or expired. **Response Body:** - **error** `string`: Human-readable error message. - **type** `string`: Error class for programmatic handling. - one of: invalid_request_error, authentication_error, permission_error, not_found, rate_limit_error, platform_error, api_error - **code** `string`: Stable machine-readable error code. - **param** `string`: The request field that caused the error, when applicable. - **docUrl** `string`: Documentation page for resolving the error, when one applies. - **platform** `string`: Upstream platform (e.g. meta, google, tiktok), present when type is platform_error. - **platformError** `object`: Raw error payload from the upstream platform, passed through verbatim so integrators can read provider-specific codes.

True when the upstream Google quota is spent rather than a Zernio limit. - **quotaScope** `string`: Google Ads and YouTube Analytics 429 only, when the scope is known. DEVELOPER is the shared budget (the developer token for Google Ads, the Google Cloud project for YouTube Analytics); ACCOUNT is your ad account (Google Ads only). - one of: DEVELOPER, ACCOUNT - **budgetScope** `string`: Zernio Google Ads burst-limit 429 only (never set alongside `quotaExhausted`). `account` is the limit of 15 requests per minute per connected Google Ads account; `user` is the ceiling of 120 requests per minute per Zernio user across all their Google Ads accounts. Both clear within a minute. - one of: account, user #### 429: The connected account's upstream platform quota is exhausted. Behavior per platform: - **Reddit:** rate-limits per connected Reddit user (1000 requests per 10-minute window), shared by every operation on that account. Retry after the window resets; repeated calls while exhausted do not succeed and keep the budget spent. - **Google Ads:** writes and reports run on one developer token shared by every Google Ads account on Zernio. It holds Standard access (no daily operations cap), so this only happens when Google throttles the token or your ad account. - **Google Ads envelope:** `code: rate_limited`, `platform: google`, `details.quotaScope: DEVELOPER` (`ACCOUNT` when it is your own ad account's quota), `details.resetsAt` (ISO instant when Google accepts requests again) and `Retry-After` counting down to it. Retrying earlier cannot succeed. - **YouTube Analytics:** reads (channel-insights, demographics, daily-views, video-retention) use the "Queries per day" quota of the Google Cloud project the account is connected through, shared with other Zernio customers, so a 429 is not your own volume. Resets at midnight Pacific Time. - **YouTube Analytics envelope:** `code: rate_limited`, `platform: google`, `details.quotaExhausted: true`, `details.quotaScope: DEVELOPER`, `details.resetsAt` and `Retry-After` counting down to it. Retrying earlier cannot succeed. - **Meta ads:** every Meta throttle (codes 4, 17, 32, 613 and business-use-case codes 80000-80014) returns 429 `rate_limited`, even when Meta answers HTTP 400. `Retry-After` comes from Meta's `x-business-use-case-usage` estimate when sent, else Meta's 60-second minimum (30 seconds for the one-write-per-30-seconds limit on one object). - **Pinterest ads:** limits per user and app, per category (ads_read, ads_write, ads_analytics). `Retry-After` comes from Pinterest's `x-ratelimit-reset` when sent, otherwise 60 seconds. - **TikTok ads:** limits per app and per endpoint (per second, minute and day), answering overage with code 40100 or code 40002 `OVER_QPS_LIMIT`. Both return 429 `rate_limited` with `platform: tiktok` and `Retry-After: 10`. Space out bulk reads (e.g. one ad at a time per advertiser) instead of retrying at once. **TikTok Smart+ review read** (`GET /v1/ads/{adId}/tiktok-smart-plus-review`) has its own stricter TikTok quota. After an overage, Zernio answers 429 for that advertiser and connection without calling TikTok for about 60 seconds, then 120, up to 240 while TikTok keeps refusing, each with up to 10% random jitter. A successful call holds nothing back; the next overage pauses about 60 seconds again. `Retry-After` is the time left. The advertiser-wide read (`GET /v1/ads/tiktok-smart-plus-reviews`) answers 200 with `retryAfterSeconds` and `refreshState` instead. Keep one request in flight per advertiser there. **Response Body:** - **error** `string`: Human-readable error message. - **type** `string`: Error class for programmatic handling. - one of: invalid_request_error, authentication_error, permission_error, not_found, rate_limit_error, platform_error, api_error - **code** `string`: Stable machine-readable error code. - **param** `string`: The request field that caused the error, when applicable. - **docUrl** `string`: Documentation page for resolving the error, when one applies. - **platform** `string`: Upstream platform (e.g. meta, google, tiktok), present when type is platform_error. - **platformError** `object`: Raw error payload from the upstream platform, passed through verbatim so integrators can read provider-specific codes. For Meta this includes error_subcode, error_user_title, and error_user_msg. - **details** `object`: Additional structured context for the error (for example field-level validation errors). What it carries depends on the endpoint and platform. **Meta ads refusals.** The ones customers hit most come back with their own `code` instead of `platform_api_error`, the field to fix in `param`, and `details.fix` ({ label, url }) pointing at the Meta page that resolves it: - `ad_account_payment_required` - `ad_account_policy_not_accepted` - `meta_security_check_required` - `meta_action_blocked` - `whatsapp_number_not_linked` - `invalid_targeting` Meta's own error stays in the message and in `platformError`. **Private replies.** `privateReplyConsumed` appears on the private-reply endpoint's 400 when the comment's single reply is already spent. `privateReplyOutcome: "unknown"` appears on its 502 when Meta answered a server error and the reply may have been delivered. **Google quota 429.** On a Google Ads or YouTube Analytics 429, `quotaExhausted: true` marks the failure as Google's own quota, not a Zernio rate limit, so you can keep calling other platforms instead of backing off everywhere. When Google names the scope, `quotaScope` is also set: - `DEVELOPER`: the shared budget (the developer token for Google Ads, the Google Cloud project for YouTube Analytics). Every account on Zernio is affected and there is nothing to change on your side. - `ACCOUNT`: your own ad account (Google Ads only). A Meta 429 carries neither field. **Zernio Google Ads burst-limit 429.** Carries `budgetScope` instead, never `quotaExhausted`. These are Zernio's own limits, applied before the call reaches Google, and both clear within a minute. They are separate axes from `quotaScope`, not the same pool named twice. - `account`: the limit of 15 requests per minute per connected Google Ads account. - `user`: the ceiling of 120 requests per minute per Zernio user across all their Google Ads accounts. **Failed Meta ad create** (`POST /v1/ads/create`, `POST /v1/ads/boost`, `POST /v1/ads/ctwa`). Carries `stage` (where it failed), `adAccountId` (on which ad account) and `createdObjects` (every object this request had already created, with what cleanup did to it). - `left_behind` objects still exist on the ad account (Meta refused the delete, typically on a held account, or the delete hit a network error). Delete them yourself or reuse them. - `unconfirmedWrite` is set when Meta answered a create with a 5xx or dropped the connection and Zernio could not confirm whether the object exists. Check that parent before creating it again. **Ineligible ad account: 422 `ad_account_unusable`.** When Meta refuses a write because the ad account's status is ineligible to manage ads (Meta subcode 2490592 or 4841021, on the write itself or on a cleanup delete), any Meta ads write answers it. That covers create, boost, CTWA, campaign / ad set / ad updates and status changes. The message names the ad account when known, links Meta's fix (https://www.facebook.com/business/help/422289316306981), lists the objects left behind and ends with Meta's original error, which also stays verbatim in `platformError`. Meta often reports the first failure under an unrelated code (e.g. 1487194 on the creative), so branch on `code`, not on `platformError`. **Missing Advertise permission: 403 `insufficient_permissions`.** When the Facebook user behind the connection's token lacks the Advertise permission on the ad account, any Meta ads write answers it. Triggers: Meta subcode 2490585, 2490591 or 4841020 on the write, or a code 200 refusal such as 1487194 whose cleanup deletes Meta refused with 2490591 or 4841020. Meta may still accept the campaign and ad set and refuse only the ad. The message names the ad account, asks for the Advertise or Manage permission on it (or a token granted `ads_management`, by reconnecting) and lists the objects left behind. It ends with Meta's `error_user_title`, `error_user_msg` and subcode; the raw error stays in `platformError`. - **stage** `string`: Meta ad create failures only. The step that failed: - `media`: image/video download or upload. - `campaign` - `adset` - `creative` - `ad`: the ad POST itself, where Meta's code 31 / 3858385 hold and 100 / 1359188 payment rejections land. - `activation`: switching the created objects on. No longer returned: a refused switch to ACTIVE now answers 201 with an `activation_failed:` warning and the objects kept PAUSED. - `other`: a read or check before any write. - one of: media, campaign, adset, creative, ad, activation, other - **adAccountId** `string`: Meta ad create failures only. The ad account the request wrote to (`act_...`). - **createdObjects** `array[object]`: Meta ad create failures only. Every object this request created before failing, in creation order. Objects you referenced (an existing campaign, ad set, creative or video) are never listed and never deleted. - **type** `string`: No description - one of: campaign, adset, creative, ad, video, image - **id** `string`: Meta object id; for `image` the image hash. - **cleanup** `string`: `deleted`: Zernio deleted it. `left_behind`: cleanup could not delete it (Meta refused the delete, or the delete hit a network error), so it still exists. `kept`: deliberately not deleted (image hashes are shared by every upload of the same file). - one of: deleted, left_behind, kept - **unconfirmedWrite** `object`: Meta ad create failures only, when Meta answered a create with a 5xx or dropped the connection and the object could not be looked up. Zernio did not retry it. - **type** `string`: No description - one of: campaign, adset, creative, ad - **parentId** `string`: Where to look for it: the ad set for an ad, the campaign for an ad set, the ad account otherwise. - **quotaExhausted** `boolean`: Google Ads and YouTube Analytics 429 only. True when the upstream Google quota is spent rather than a Zernio limit. - **quotaScope** `string`: Google Ads and YouTube Analytics 429 only, when the scope is known. DEVELOPER is the shared budget (the developer token for Google Ads, the Google Cloud project for YouTube Analytics); ACCOUNT is your ad account (Google Ads only). - one of: DEVELOPER, ACCOUNT - **budgetScope** `string`: Zernio Google Ads burst-limit 429 only (never set alongside `quotaExhausted`). `account` is the limit of 15 requests per minute per connected Google Ads account; `user` is the ceiling of 120 requests per minute per Zernio user across all their Google Ads accounts. Both clear within a minute. - one of: account, user #### 503: Organic Reddit is temporarily unavailable while Reddit blocks third-party API access (`PLATFORM_DISABLED`). --- # Related Schema Definitions ## RedditPost A normalized Reddit post returned by the feed and search endpoints ### Properties - **id** `string`: Reddit post ID (without type prefix) - **fullname** `string`: Reddit fullname (e.g. t3_abc123) - **title** `string`: No description - **author** `string`: No description - **subreddit** `string`: No description - **url** `string`: Post URL (may be a gallery URL, external link, or self-post URL) - **permalink** `string`: Full permalink to the Reddit post - **selftext** `string`: Self-post body text (empty string for link posts) - **createdUtc** `number`: Unix timestamp of post creation - **score** `integer`: No description - **numComments** `integer`: No description - **over18** `boolean`: Whether the post is marked NSFW - **stickied** `boolean`: No description - **flairText** `string,null`: Link flair text if set - **isGallery** `boolean`: Whether the post is a gallery with multiple images - **galleryImages** `array`: Individual image URLs for gallery posts (only present when isGallery is true) ## ErrorResponse Canonical error envelope. `error` is the human-readable message; `type`, `code`, `param`, `platform`, and `platformError` are top-level siblings for programmatic handling. For upstream platform failures (`type: platform_error`), `platformError` carries the provider's raw payload verbatim (for Meta: `error_subcode`, `error_user_title`, `error_user_msg`). ### Properties - **error** `string`: Human-readable error message. - **type** `string`: Error class for programmatic handling. - one of: invalid_request_error, authentication_error, permission_error, not_found, rate_limit_error, platform_error, api_error - **code** `string`: Stable machine-readable error code. - **param** `string`: The request field that caused the error, when applicable. - **docUrl** `string`: Documentation page for resolving the error, when one applies. - **platform** `string`: Upstream platform (e.g. meta, google, tiktok), present when type is platform_error. - **platformError** `object`: Raw error payload from the upstream platform, passed through verbatim so integrators can read provider-specific codes. For Meta this includes error_subcode, error_user_title, and error_user_msg. - **details** `object`: Additional structured context for the error (for example field-level validation errors). What it carries depends on the endpoint and platform. **Meta ads refusals.** The ones customers hit most come back with their own `code` instead of `platform_api_error`, the field to fix in `param`, and `details.fix` ({ label, url }) pointing at the Meta page that resolves it: - `ad_account_payment_required` - `ad_account_policy_not_accepted` - `meta_security_check_required` - `meta_action_blocked` - `whatsapp_number_not_linked` - `invalid_targeting` Meta's own error stays in the message and in `platformError`. **Private replies.** `privateReplyConsumed` appears on the private-reply endpoint's 400 when the comment's single reply is already spent. `privateReplyOutcome: "unknown"` appears on its 502 when Meta answered a server error and the reply may have been delivered. **Google quota 429.** On a Google Ads or YouTube Analytics 429, `quotaExhausted: true` marks the failure as Google's own quota, not a Zernio rate limit, so you can keep calling other platforms instead of backing off everywhere. When Google names the scope, `quotaScope` is also set: - `DEVELOPER`: the shared budget (the developer token for Google Ads, the Google Cloud project for YouTube Analytics). Every account on Zernio is affected and there is nothing to change on your side. - `ACCOUNT`: your own ad account (Google Ads only). A Meta 429 carries neither field. **Zernio Google Ads burst-limit 429.** Carries `budgetScope` instead, never `quotaExhausted`. These are Zernio's own limits, applied before the call reaches Google, and both clear within a minute. They are separate axes from `quotaScope`, not the same pool named twice. - `account`: the limit of 15 requests per minute per connected Google Ads account. - `user`: the ceiling of 120 requests per minute per Zernio user across all their Google Ads accounts. **Failed Meta ad create** (`POST /v1/ads/create`, `POST /v1/ads/boost`, `POST /v1/ads/ctwa`). Carries `stage` (where it failed), `adAccountId` (on which ad account) and `createdObjects` (every object this request had already created, with what cleanup did to it). - `left_behind` objects still exist on the ad account (Meta refused the delete, typically on a held account, or the delete hit a network error). Delete them yourself or reuse them. - `unconfirmedWrite` is set when Meta answered a create with a 5xx or dropped the connection and Zernio could not confirm whether the object exists. Check that parent before creating it again. **Ineligible ad account: 422 `ad_account_unusable`.** When Meta refuses a write because the ad account's status is ineligible to manage ads (Meta subcode 2490592 or 4841021, on the write itself or on a cleanup delete), any Meta ads write answers it. That covers create, boost, CTWA, campaign / ad set / ad updates and status changes. The message names the ad account when known, links Meta's fix (https://www.facebook.com/business/help/422289316306981), lists the objects left behind and ends with Meta's original error, which also stays verbatim in `platformError`. Meta often reports the first failure under an unrelated code (e.g. 1487194 on the creative), so branch on `code`, not on `platformError`. **Missing Advertise permission: 403 `insufficient_permissions`.** When the Facebook user behind the connection's token lacks the Advertise permission on the ad account, any Meta ads write answers it. Triggers: Meta subcode 2490585, 2490591 or 4841020 on the write, or a code 200 refusal such as 1487194 whose cleanup deletes Meta refused with 2490591 or 4841020. Meta may still accept the campaign and ad set and refuse only the ad. The message names the ad account, asks for the Advertise or Manage permission on it (or a token granted `ads_management`, by reconnecting) and lists the objects left behind. It ends with Meta's `error_user_title`, `error_user_msg` and subcode; the raw error stays in `platformError`. - **stage** `string`: Meta ad create failures only.
