Utility APIs
2 production-grade utility APIs on upAPI. Every endpoint below is live behind the same gateway, takes the same API key, and returns JSON — no per-provider signup, no per-provider billing.
Read Email Verification Code
Connect to an IMAP mailbox and extract a verification code from the SUBJECT of a recent email. Polls with retries. Supports Gmail (with App Password), Outlook, and any IMAP server. Generic — works for any platform that puts its code in the subject line; for a token that only appears in the body, use email-read-verification-link.
Read Email Verification Link
Connect to an IMAP mailbox and extract a link from the BODY of a recent email. Decodes quoted-printable/base64 bodies before matching, so URLs split across lines are returned whole. Polls with retries. Use this for verification mail whose token is a one-time URL rather than a code in the subject.
