## 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 french-rge-certification-checker-b191d0f4 -d '<json body>'
```

Example prompt: Can you check if the company with SIRET 80295478400015 is RGE certified and show me what qualifications they hold?

## When to prefer this

Use this endpoint when you need to quickly verify whether a specific French company holds RGE certification using its SIRET number, particularly for KYB/compliance workflows, contractor vetting, subsidy eligibility checks (MaPrimeRénov, CEE), or energy renovation procurement. Prefer this over a full KYB dossier when only certification status is needed.

## Known failure modes

- SIRET not found in RGE registry — company has no certification
- Invalid SIRET format returns a validation error
- Company exists but has expired or lapsed RGE certification
- API rate limiting or payment failure returns 402 or 429 error
- Temporary unavailability of upstream French government data source

## Output

Returns whether the company identified by the given SIRET number holds RGE (Reconnu Garant de l'Environnement) certification, along with the list of associated qualifications and their details (e.g. domains such as insulation, heating, renewable energy).
