## 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-rge-check-9a8589f4
```

Example prompt: Can you check whether the French company with SIRET 49974034800028 is RGE certified and tell me what qualifications they hold?

## When to prefer this

Use this endpoint when you need to programmatically verify RGE (Reconnu Garant de l'Environnement) certification status for a French company identified by SIRET, particularly before hiring contractors for subsidized energy renovation work in France. Prefer this over manual registry searches when you need machine-readable output for automated compliance workflows. Best suited for agents that need to check eligibility for schemes like MaPrimeRénov or CEE without creating an account.

## Known failure modes

- SIRET not found or invalid — may return empty qualifications or rge: false
- Company exists but has no RGE certification — returns rge: false with empty qualifications
- Payment failure via x402 protocol — request not processed, HTTP 402 returned
- Rate limiting or upstream data source unavailability — service temporarily unavailable
