# Get latest OTP

GET https://api2.freecustom.email/v1/inboxes/{inbox}/otp

Returns the OTP and/or verification link from the most recent message
that contains one. Requires Growth plan or higher.

On lower plans, message list endpoints return `otp: "__DETECTED__"` as a
hint that an OTP exists — use this endpoint (Growth+) to read the
actual value.
