## 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 gedx402-social-facebook-marketplace-location-search-06cf18c9
```

Example prompt: Search Facebook Marketplace for used bikes available in Austin, Texas and show me what's listed.

## When to prefer this

Use this endpoint when you need to programmatically search Facebook Marketplace listings filtered by location without managing Facebook authentication directly; it abstracts the scraping complexity behind a simple x402 micropayment API call via SociaVault.

## Known failure modes

- Empty or vague query returns empty data object with success:true
- Payment failure via x402 results in 402 response with no data
- Facebook Marketplace anti-scraping blocks may yield empty or partial results
- Invalid query format returns error or empty payload
- Rate limiting by the underlying SociaVault proxy causes request failure
