## 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 strale-kyb-essentials-france-c0a94eaf -d '<json body>'
```

Example prompt: Run a KYB essentials check on the French company with SIREN number 552 032 534 and tell me its legal status, registered address, and activity code.

## When to prefer this

Choose this endpoint when you need authoritative KYB data on a French company and have its SIREN or SIRET number. It is purpose-built for France, returns a cryptographic audit trail suitable for compliance workflows, and costs a flat $1.62 USDC per call via x402 micropayment — ideal for agent-driven due diligence, vendor onboarding, or pre-payment checks on French entities where auditability is required.

## Known failure modes

- Invalid or malformed SIREN/SIRET returns a 400 validation error
- SIREN/SIRET not found in French registry returns a 404 not found response
- Inactive or deregistered company may return data with a ceased status
- x402 payment failure or insufficient USDC balance blocks the request
- Rate limiting or upstream registry unavailability returns a 503 or timeout

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

A structured JSON object containing official French company data (name, legal form, registration status, registered address, NAF/APE activity code, incorporation date, etc.) sourced from authoritative registries, plus a cryptographic audit record with chain hashing for compliance documentation.
