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
A JSON object containing the company name, a boolean validity flag, the 2-letter country code, and the VAT number as confirmed by the registry. No personal data of natural persons is included.
Example use cases
Supplier VAT verification before payment
“Before I pay this German supplier, can you verify their VAT number DE811569869 is valid and tell me the company name it's registered to?”
Polish company whitelist check
“I need to confirm that the Polish company with VAT number PL5261040828 is on the MF VAT whitelist — can you look that up for me?”
Cross-border invoice compliance check
“We're about to issue a zero-rated B2B invoice to a French company with VAT number FR40303265045 — can you verify it's a valid registered EU VAT number?”
Technical details
Endpoint
GEThttps://plreg.x402utils.workers.dev/v1/eu-vat?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate EU VAT numbers against the official EC VIES system or specifically check Polish companies against the MF VAT whitelist and KRS registry. It is the right choice for B2B invoice compliance, supplier due diligence, or cross-border EU trade verification. Prefer it over generic company lookup APIs when official EU tax registry confirmation is required, and when a micropayment-per-call model (USDC on Base via x402) is acceptable.
Side effects
- Invalid or malformed VAT number format returns validation failure
- VAT number not found in VIES or Polish registry returns valid:false
- Country prefix not supported by EC VIES returns an error
- Payment failure via x402/USDC blocks the request
- VIES service temporarily unavailable returns upstream error
