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 field: true if the SSN passes format and structural validation, false if it does not. No additional detail is returned about why a number may be invalid.
Example use cases
KYC onboarding SSN check
“Before we proceed with this user's account application, can you validate that the SSN they provided — 123-45-6789 — is correctly formatted and passes validation?”
Form submission pre-validation
“The user typed '987654321' as their SSN on the signup form — can you verify that number is valid before we send it to the backend?”
Data quality audit
“I have an SSN from our records: 456-78-9012. Please check whether it's a valid Social Security Number so I can flag it for review if not.”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/ssn_validateWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call SSN format and structural validator with no signup or API key required. Ideal for agents performing KYC pre-checks, form validation, or data quality audits on US Social Security Numbers. Prefer this over full identity verification services when you only need format/checksum validation, not a live database lookup.
Side effects
- Invalid SSN format submitted (not NNN-NN-NNNN or 9 digits) — likely returns ok: false
- Missing required 'ssn' field in body — request may return an error
- SSN with all-zero segment (e.g. 000-00-0000) may fail validation rules
- Network or payment failure via x402 — 402 response if USDC balance insufficient
