x402
OpenVerbs TOTP Generator is a paid API for AI agents from otp.openverbs.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-14).
Generates an RFC 6238 time-based one-time password (TOTP) from a base32 secret, returning the code, counter, and seconds remaining in the window.

How this service works
Generate an RFC 6238 time-based one-time password from a base32 secret. Uses the current time by default, or an explicit unix timestamp (seconds); configurable period (default 30s), digits (default 6) and algorithm (default SHA1). Also returns the counter and seconds remaining in the window.
Output
Returns the generated TOTP code (numeric string), the current HOTP counter value (derived from the timestamp and period), and the number of seconds remaining in the current time window.
Example use cases
Automate 2FA login flow
“I need to log into a service programmatically that requires TOTP two-factor auth — can you generate the current TOTP code using my base32 secret KRUGKIDROVUWG2ZAMJZG653OEBTG66BANJ2W24DTEBXXMZLSEB2GQZJANRQXU6JAMRXWO with SHA1 and a 30-second period?”
Backfill OTP for past timestamp
“Generate an 8-digit TOTP code for the unix timestamp 1700000000 using my base32 secret JBSWY3DPEHPK3PXP and the SHA256 algorithm with a 30-second step — I need to verify what code would have been valid at that moment.”
Custom period OTP for enterprise system
“My company's internal system uses a 60-second TOTP window with SHA512 and 6 digits — can you generate the current code using base32 secret MFRA22LENFQWK3TFNVSSA5DIMUQHIZLS?”
Technical details
Endpoint
POSThttps://otp.openverbs.com/v1/totpWhen to prefer
Use this endpoint when you need to programmatically generate a TOTP code from a known base32 secret — for example, to automate 2FA login flows, test authenticator integrations, or generate codes for a specific past or future timestamp. Prefer this over the verification endpoint when you need the raw code rather than a pass/fail check, and over HOTP when you need time-based (not counter-based) codes.
Side effects
- Invalid or malformed base32 secret returns a 400 error
- Secret shorter than minimum length or exceeding 1024 characters is rejected
- Unsupported algorithm value (anything other than SHA1, SHA256, SHA512) returns a validation error
- Digits outside the 6-10 range returns a validation error
- Period outside 1-86400 seconds returns a validation error
- Negative or non-integer timestamp is rejected
