## 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 quantaflow-serp-facebook-profile-lookup-c3b42ac2 -d '<json body>'
```

Example prompt: Search Facebook for profiles matching 'John Smith' and give me the top results including profile links and any available metadata.

## When to prefer this

Use this endpoint when you need programmatic access to Facebook profile SERP data on a pay-per-call basis without a subscription, and your agent is capable of handling x402 micropayment flows in USDC. Prefer this over scraping directly when you need a managed gateway with per-request pricing.

## Known failure modes

- Payment failure if USDC balance is insufficient or x402 payment header is missing
- Upstream SERP provider unavailable or rate-limited
- Empty results if the queried name has no matching Facebook profiles
- Invalid or malformed query parameters returning an error response
- Gateway timeout if the upstream provider is slow to respond

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

Returns the upstream SERP response containing Facebook profile search results, including profile names, links, and any available public metadata, passed through directly after successful x402 micropayment processing.
