How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns a structured validation result indicating whether the phone number is valid, its normalized E.164 format, detected country code, number type (mobile/landline/VOIP/etc.), and a cryptographic audit record with chain hashing for traceability. Invalid or unrecognized numbers return an appropriate error or invalid status.
Example use cases
Signup form phone verification
“Before we create this new user account, validate the phone number they entered — +1 415 555 0198 — and confirm it's a real US number.”
International contact list cleanup
“I have a contact with the phone number 0033 6 12 34 56 78 — can you validate it and tell me if it's a valid French mobile number?”
Fraud detection phone check
“A new order came in with the phone number +55 11 98765-4321 listed as a Brazil contact — can you verify that's a legitimate, correctly formatted Brazilian number?”
Technical details
Endpoint
GEThttps://api.strale.io/x402/v2/phone-validateWhen to prefer
Choose this endpoint when you need tamper-evident, auditable phone validation with a cryptographic chain hash — ideal for compliance-sensitive workflows, fraud prevention pipelines, or regulated industries. It covers 27 countries and supports any phone number format as input, making it suitable for messy, user-submitted data. Prefer over generic validation libraries when you need a REST/MCP/x402-compatible call with a returned audit record rather than a local validation function.
Side effects
- Invalid or unparseable phone number format returns a validation failure or error status
- Missing required phone_number query parameter returns a 400 Bad Request
- Ambiguous number without country_code hint may return incorrect country assignment
- Very unusual or newly assigned number ranges may not be recognized
- Network timeout or upstream service error returns 5xx response
