Send a 6-digit verification code to a phone number via SMS.
Use this instead of sending your own code over `POST /v1/messages`: it
routes through carrier-registered sender IDs, so it reaches countries
where plain application SMS from a US long code is not deliverable
(e.g. Greece, UAE, the Philippines, the UK).
The code is always 6 digits, expires after 10 minutes, and allows up to
3 check attempts. None of these are configurable.
**Billing.** Sending a code costs the standard outbound SMS rate for the
destination country. A successful `POST /v1/verify/check` adds a $0.05
verification fee; failed, expired, and exhausted checks are not charged.
**Destination coverage.** A small number of countries are unavailable and
return 400. Email
[email protected] if you need access to one.
