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
Returns a JSON object with an 'ok' boolean indicating whether the provided NINO string is valid. A true value means the NINO passes format and validity checks; false means it does not conform to the expected UK National Insurance Number pattern.
Example use cases
Employee onboarding NINO check
“Before I submit this new hire's payroll details, can you verify their National Insurance number 'QQ 12 34 56 C' is in the correct format?”
Form submission pre-validation
“A user just entered 'AB1234567' as their NI number on our signup form — is that a valid NINO or should I ask them to correct it?”
Benefits eligibility verification
“I need to confirm that the NI number 'AB 12 34 56 A' provided by this benefits applicant is properly formatted and valid before processing their claim.”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/nino_validateWhen to prefer
Choose this endpoint when you need a quick, pay-per-call NINO validation without setting up a dedicated UK identity verification service or API key. Ideal for low-volume or ad-hoc checks in agent workflows handling UK employment, payroll, or benefits processes where you want instant format validation at minimal cost ($0.001 USDC per call).
Side effects
- Malformed input string that cannot be parsed as a NINO — returns ok: false
- Missing required 'value' field in body — returns validation/schema error
- Payment failure via x402 — HTTP 402 response if USDC payment not completed
- Network timeout or service unavailability — HTTP 5xx error
