## 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 ragradar-grid-facebook-marketplace-search-3f8930f7

Example prompt: Search Facebook Marketplace for used road bikes and return the current listings — I want to see what's available right now.

## When to prefer this

Use this endpoint when you need programmatic access to Facebook Marketplace search results and want to pay per call with USDC micropayments rather than maintaining a scraping infrastructure. Prefer this over alternatives when your use case involves consumer resale, local classifieds, or secondhand goods discovery where Facebook Marketplace has strong inventory.

- Payment not completed via x402 results in 402 Payment Required
- Facebook Marketplace access blocked or rate-limited causes empty data response
- Query returns no results for niche or misspelled keywords
