## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability factline-eori-validation-131083a6
```

Example prompt: Can you check if the EORI number IE6388047V is valid and registered with the European Commission, and tell me the trader's name and address if they've made them public?

## When to prefer this

Use this endpoint when you need to validate EU EORI numbers in real time against the official European Commission source — ideal for customs compliance, logistics pre-checks, KYB onboarding, and e-commerce cross-border workflows. Prefer this over internal or cached databases when authoritative, live validation is required. Note: does not support GB EORI numbers.

## Known failure modes

- Invalid or malformed EORI number format returns an error or invalid status
- GB (post-Brexit) EORI numbers are not supported and will fail or return invalid
- Trader details (name/address) may be absent if the trader has not opted to publish them
- Service may be temporarily unavailable if the European Commission's upstream validation service is down
- Rate limits or payment failures may result in request rejection

## How this service works

API and MCP servers that let AI agents and apps check people, companies, Dutch addresses and cars against official records: sanctions and PEP lists, 10 company registers, Dutch property, rent and RDW vehicle data. From $0.001 per call.

## Output

Returns whether the EORI number is registered and valid according to the European Commission's official service. When the trader has consented to publish their details, also returns the registered trader name and address. Covers all EU member states; GB numbers are not supported.
