How this service works
Send a one-time verification code to a phone number.
Output
Returns a confirmation that the OTP has been dispatched to the specified phone number via the chosen channel. May include a session or reference ID for correlating the subsequent verification step.
Example use cases
New user phone verification at signup
“A new user just entered their phone number +447911123456 during signup — send them a 6-digit OTP via WhatsApp so they can verify their number before continuing.”
Two-factor auth via SMS fallback
“My user with ID 'acct-789-xyz' needs a 4-digit verification code sent by SMS to +33612345678 — WhatsApp isn't available for them.”
Voice OTP for accessibility
“Send a 6-digit one-time code via voice call to +61412345678 for user 'user-456@example.com' — they can't read texts easily and prefer to hear the code read aloud.”

Endpoint
POSThttps://x402.orth.sh/didit/v3/phone/send?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to send a one-time verification code to a phone number as part of a user authentication or onboarding flow, especially when you need multi-channel flexibility (WhatsApp, SMS, Telegram, or voice) and built-in fraud signal support. It is particularly useful in agentic workflows where you want to verify user identity before proceeding, and when you need per-channel control and locale-aware OTP delivery backed by Didit's infrastructure.
Side effects
- Invalid phone number format (not E.164) — rejected with validation error
- Unsupported locale or channel combination — error response
- Rate limiting if too many codes sent to the same number in a short period
- Carrier or channel delivery failure — message not delivered
- Invalid code_size value outside 4-8 range — input error
- Payment failure ($0.30 USDC not available) — 402 response before message is sent
