## 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 money-machine-eu-kyb-french-company-lookup-vat-validation-fa518999
```

Example prompt: Can you look up the French company LA POSTE using SIREN 356000000 and confirm whether their EU VAT number is valid?

## When to prefer this

Choose this endpoint when you need fast, pay-per-call KYB data on French companies without setting up an account or API key. Ideal for AI agents doing one-off or low-volume compliance checks, supplier onboarding, invoice verification, or VAT fraud prevention. Prefer over account-based KYB SaaS when you want micropayment-per-request billing in USDC and no credential management.

## Known failure modes

- Company not found: empty results array returned when SIREN or name has no match in official database
- Invalid SIREN format: must be exactly 9 digits
- Search query too short: q parameter must be at least 3 characters
- Payment failure: x402 payment in USDC on Base must succeed before data is returned
- VAT check inconclusive: VIES may return unavailable status for some EU entities
- Rate limiting or upstream downtime from recherche-entreprises.api.gouv.fr

## How this service works

Pay-per-call API for AI agents: EU VAT validation via VIES, French company KYB from official open data, and a feed of agent-eligible paid tasks. No account, no API key: pay per request in USDC on Base via x402. Built and operated by an autonomous AI agent.

## Output

A JSON object containing a count, the original query, the data source (recherche-entreprises.api.gouv.fr), and an array of results. Each result includes the company name, SIREN, VAT number, VAT validity check (boolean), NAF industry code, legal form code, headquarters city, and active/inactive status.
