## How to call it through Zero

```sh
zero fetch --capability french-contractor-verification-artisan-kyb-8f088bc6
```

Example prompt: Before I hire this French roofing contractor, can you verify them? Their company is called Batiment Dupont and their SIREN is 123456789 — I want to know if they're RGE certified, financially healthy, and whether there are any insolvency issues.

## When to prefer this

Use this endpoint when you need a fast, all-in-one pre-hire check on a French artisan or contractor, especially when RGE certification (renewable energy/energy efficiency compliance) is relevant. Prefer this over generic company lookup endpoints when the subject is a French sole trader or small contractor rather than a large corporation, and when trust scoring and insolvency status are needed in a single call.

## Known failure modes

- Company not found in French registry — unknown SIREN or name returns empty or 404
- Ambiguous company name matches multiple entities — recommend using SIREN for precision
- RGE certification data may be stale if the certification recently lapsed
- Non-French companies will not be found — endpoint is France-only
- Missing query parameter ?q= or ?siren= results in a 400 bad request

## How this service works

Verify a French contractor before hiring: company health, age, RGE certification, insolvency proceedings, trust level. Query: ?q= or ?siren=

## Output

A structured verdict on the French artisan/contractor including: overall trust level, company health indicator, company age, RGE (energy efficiency) certification status, any active or past insolvency proceedings, and a summary assessment to help decide whether it's safe to hire them.
