How this service works
EU VAT validation (EC VIES) and Polish company registry lookups (MF VAT whitelist + KRS), paid per call via x402 (USDC on Base). Company-level data only; no personal data of natural persons is returned.
Output
Returns a JSON object with an 'assigned' boolean indicating whether the provided bank account number is assigned to the given NIP on the Polish Ministry of Finance VAT whitelist, plus an 'mf_request_id' string for audit/traceability purposes.
Example use cases
Supplier payment due diligence
“I'm about to wire money to a Polish vendor with NIP 5260250274 — can you verify that their bank account 27114020040000300201355387 is actually listed on the Ministry of Finance VAT whitelist before I approve the transfer?”
Accounts payable fraud prevention
“Our finance team received an invoice from a Polish company (NIP 5213003700) with a new bank account number 61109010140000071219812874 — can you check if this account is on the MF VAT whitelist so we know it's legitimate?”
Automated vendor onboarding check
“We're onboarding a new Polish supplier with NIP 6762460150 and bank account 83102052260000670200516863 — please verify their account is on the Polish VAT whitelist as part of our KYB process.”
Technical details
Endpoint
GEThttps://plreg.x402utils.workers.dev/v1/pl-vat-account-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific Polish bank account is assigned to a known NIP on the official MF VAT whitelist — essential for split-payment compliance, supplier due diligence, or fraud prevention in Polish B2B transactions. Prefer this over manual MF portal lookups when automating accounts-payable workflows or vendor onboarding pipelines.
Side effects
- Invalid or malformed NIP returns an error response
- Bank account not in 26-digit NRB format causes a validation error
- NIP not found in the MF registry returns assigned: false rather than an error
- Network or MF API outage may cause timeouts or 5xx errors
- Payment failure (insufficient USDC balance) blocks the request via x402 protocol
