Request a higher sender ID daily limit
Asks support to raise the workspace's daily sender-ID message cap. There is no self-serve raise: the request (desired cap + use case) is reviewed manually, usually within a business day.

}Look up carrier + line type GET
Carrier name and line type (mobile / landline / voip / toll-free) for a number, plus `smsReachable` (landlines can't receive SMS). Use it to validate recipients before sending. Each lookup is billed by the carrier-data provider, so call it explicitly (e.g. pre-validating an opt-in list), not on every send.
Re-send the sole-prop OTP POST
Re-sends the sole-proprietor verification PIN to the brand's mobile number — use it when the original code expired or never arrived. Only valid while the registration is pending and awaiting its OTP; rate limited to one send per minute.
