## 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 scopeapi-facebook-marketplace-search-76f538e9
```

Example prompt: Search Facebook Marketplace for 'vintage leather couch' and show me what listings come up, including prices and seller info.

## When to prefer this

Use this endpoint when you need programmatic, pay-per-call access to Facebook Marketplace search results without managing Facebook credentials or scraping infrastructure. Prefer this over building your own scraper when you need occasional lookups at $0.75/call. Best for price research, inventory monitoring, or competitive intelligence on secondhand goods.

## Known failure modes

- Missing required 'q' query parameter returns an error or empty results
- Payment failure (402) if USDC micropayment not provided or insufficient
- Facebook Marketplace access blocked or rate-limited returning empty or error data
- Query returning zero results for niche or misspelled search terms
- Network timeout on the Vercel-hosted endpoint under load
