## 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 x402-farm-french-artisan-verification-api-ab748998
```

Example prompt: Can you verify whether this French artisan or contractor is RGE certified and check their professional standing — I want to know the confidence level and whether they have any collective procedures on record?

## When to prefer this

Use this endpoint when you need to verify the RGE certification status and professional standing of a French artisan or contractor, especially in contexts involving energy renovation grants, marketplace onboarding, or pre-hire due diligence. It is well-suited for AI agents that need pay-per-call access without account registration, using USDC micropayments via the x402 protocol. Prefer this over manual registry lookups when automation and structured output are required.

## Known failure modes

- Artisan not found in registry — may return low confidence or null certification status
- Payment failure via x402 protocol before response is served
- Invalid or missing input parameters return schema validation errors
- Registry data may be outdated if the artisan's certification recently lapsed
- Network timeout from upstream French government data source

## How this service works

Pay-per-call APIs for AI agents — x402 protocol, USDC on Base, no account needed.

## Output

Returns a JSON object with a confidence level ('confiance', e.g. 'élevée' meaning high), a boolean indicating RGE certification status ('certifie_rge'), and a count of collective insolvency or legal procedures ('procedures_collectives'). This enables downstream decisions about contractor trustworthiness and regulatory compliance.
