## When to prefer this

Use this endpoint when you need to identify qualified, government-certified (RGE) renovation contractors in France by geographic area and trade specialty — particularly when helping users access state subsidies (MaPrimeRénov, CEE, etc.) that require RGE-certified contractors. Prefer this over generic business search APIs when the RGE certification status is a hard requirement.

## Known failure modes

- No contractors found for the given postal code and domain combination — empty result list
- Invalid or non-existent French postal code — may return error or empty response
- Unsupported or misspelled trade domain — may return no results
- Missing required query parameters (cp or domaine) — likely returns 400 bad request
- Postal code in a low-density area with no registered RGE contractors
