How this service works
Wait (blocking, up to 90s) for an SMS verification code / OTP to arrive on a phone number you own, and return the parsed code. Body (all optional): { timeout_s (default 60, max 90), lookback_s (default 10; pass 0 for reused numbers), pattern (custom regex, max 256 chars) }
Output
Returns the parsed OTP/verification code extracted from the SMS that arrived on the specified phone number, along with metadata about the matched message.
Example use cases
Automated account signup verification
“I just triggered a phone verification for the new account I'm creating — wait up to 90 seconds for the SMS OTP to arrive on phone number ID ph_xyz789 and give me the code so I can complete the signup.”
2FA login flow automation
“I've initiated a login that requires a 2FA code by SMS — block for up to 60 seconds waiting for it to land on phone number ID ph_def456 and return the one-time password so I can submit it.”
Disposable number OTP capture
“I'm using a freshly assigned disposable number with ID ph_ghi321 — set lookback to 0 since it may have prior messages, wait up to 90 seconds for the verification SMS to arrive, and extract the numeric code for me.”
Technical details
Endpoint
POSThttps://palmyr.ai/phone/numbers/:id/wait-otpWhen to prefer
Use this endpoint when your agent needs to autonomously complete an SMS-based verification or 2FA flow on a phone number it controls, especially in automated signup, login, or account verification workflows where waiting for the OTP inline (up to 90s) is acceptable.
Side effects
- Timeout: no OTP arrives within the specified timeout window (up to 90s), returning a timeout error
- Pattern mismatch: an SMS arrives but no code matches the expected pattern
- Invalid phone number ID: the specified number does not belong to the authenticated wallet
- Invalid regex pattern: the custom pattern exceeds 256 characters or is malformed
- Payment failure: the $0.02 USDC x402 payment is not completed or rejected
