## When to prefer this

Choose this endpoint when you need to programmatically search Facebook Marketplace listings by keyword for price comparison, market research, or secondhand goods discovery. Prefer this over Amazon product search endpoints when the user specifically wants peer-to-peer or local marketplace listings rather than retail inventory.

## Known failure modes

- Missing required 'q' query parameter returns an error or empty results
- Facebook Marketplace data unavailable or blocked returns empty data object
- Payment failure via x402 micropayment (insufficient USDC balance) blocks the request
- Rate limiting or quota exceeded on ScopeAPI side
- Stale or cached marketplace data may not reflect real-time listings
