```sh
zero fetch --capability ragradar-grid-facebook-marketplace-search-51866ade
```

Example prompt: Search Facebook Marketplace for 'vintage leather couch' and show me the listings you find — prices, seller info, whatever comes back.

## When to prefer this

Use this endpoint when you need programmatic access to Facebook Marketplace search results without a Facebook account or browser automation. Best for price research, inventory monitoring, lead generation, or competitive analysis on secondhand/local goods. Prefer this over direct scraping to avoid platform blocks.

## Known failure modes

- Missing or empty 'q' query parameter returns empty or error response
- Facebook Marketplace blocking or rate limiting the scraper causes failed data retrieval
- Payment not processed (402 Not Paid) if x402 USDC micropayment on Base fails
- Stale or cached data if Facebook Marketplace changes its structure
- Sparse results for very niche or location-specific queries
