## 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-post-search-c8d0133a
```

Example prompt: Search Facebook posts about 'electric vehicles' and show me what people are publicly saying about it right now.

## When to prefer this

Use this endpoint when you need to search and retrieve public Facebook post data by keyword for social listening, market research, brand monitoring, or competitive intelligence. Prefer this over generic web search when Facebook-specific social content is explicitly needed and you are prepared to pay per call via USDC micropayment.

## Known failure modes

- Missing or empty q parameter returns no results or an error
- Payment not completed (402 response) blocks data access
- Rate limiting if too many calls are made in quick succession
- Facebook data unavailability or access restrictions may return empty data
- Invalid or overly broad queries may return generic or low-quality results

## How this service works

37 paid REST endpoints: Facebook social & ads intelligence, Amazon e-commerce data, job market intelligence. Pay per call via x402 micropayments (USDC on Base).

## Output
