## When to prefer this

Use this endpoint when you need to search French classified ads on LeBonCoin without signing up or managing API keys. Ideal for price research, inventory discovery, or market analysis on the French second-hand consumer goods market. Prefer this over scraping directly when you need pay-per-call simplicity with no subscription overhead.

## Known failure modes

- Missing required 'query' parameter returns an error
- Invalid page number outside 1-100 range may return empty results or error
- Non-French or poorly spelled query terms may yield few or no results
- LeBonCoin rate limiting or site changes may cause upstream failures
- Payment failure (x402) results in no charge and no data returned
