How this service works
The OpenRouter for AI-agent tools: one gateway, one wallet, every capability. Built-in tools, forged tools, a global verified business directory and 2,000+ aggregated x402 services, all paid per call in USDC via x402 (HTTP 402). No signup, no API key.
Output
A JSON object with an 'ok' boolean field indicating whether the provided 18-character CURP code is valid (true) or invalid (false).
Example use cases
KYC onboarding for Mexican users
“I'm onboarding a Mexican customer and they gave me their CURP as GODE561231HDFRRR09 — can you verify that it's a valid CURP before I proceed?”
Form validation before database entry
“Before I save this record, check that the CURP BADD110313HCMLNS09 is a properly formatted and valid Mexican CURP code.”
Bulk data quality check on a single record
“I have a user profile where the CURP field is TOMA720416MDFRRR05 — is that a valid Mexican CURP?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/curp_validateWhen to prefer
Use this endpoint when you need to validate a Mexican CURP (Clave Única de Registro de Población) code offline-style via a lightweight API call, without needing a full government registry lookup. It is ideal for KYC pipelines, form validation, and data quality checks for Mexican user records. Prefer it over a manual regex check when you want a reliable, maintained validator that handles format and checksum rules, paid per call with no signup or API key required.
Side effects
- Missing or malformed 'curp' field in request body returns a validation error
- CURP with incorrect length (not 18 characters) returns ok: false
- Invalid checksum digit causes ok: false
- Network or payment failure (402 if wallet is empty) prevents the call from completing
- Malformed JSON body returns a 400-level error
