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 indicating whether the PESEL number is valid. May include additional parsed metadata such as date of birth or gender encoded in the PESEL structure.
Example use cases
KYC onboarding for Polish users
“I need to verify a new Polish customer's PESEL before approving their account — can you validate 85032109875 and tell me if it's a legitimate number?”
Form input validation before submission
“Before I submit this registration form, check whether the PESEL the user entered is valid: 96072812345.”
Data quality check on imported records
“I've got a batch of Polish user records and I need to confirm this PESEL is correctly formatted and passes the checksum: 02270803628 — is it valid?”
Technical details
Endpoint
POSThttps://toll402.dev/v1/t/pesel_validate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, offline, per-call PESEL validation without setting up any API keys or accounts. Ideal for AI agents doing on-the-fly KYC checks, form validation, or data quality audits on Polish national ID numbers. Prefer this over building your own checksum logic when you want a verified, maintained implementation accessible via a simple HTTP call paid in USDC.
Side effects
- Invalid or malformed PESEL (wrong length, non-numeric characters, failed checksum) returns ok: false
- Missing required 'pesel' field in request body causes validation error
- Non-string input type may cause schema validation failure
- Payment failure via x402 returns HTTP 402 before processing
