## 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 stablesocial-facebook-marketplace-search-006e6a4f -d '<json body>'
```

Example prompt: Search Facebook Marketplace for used road bikes within 30km of downtown Chicago (41.8781, -87.6298), return 10 listings sorted by price ascending, condition used_good or better, priced between $100 and $800, listed in the last 30 days.

## When to prefer this

Choose this endpoint when you need programmatic, no-auth access to Facebook Marketplace search results with fine-grained filtering by location radius, price, condition, date, and delivery method. Ideal for price research, inventory monitoring, lead generation for resellers, or building local commerce tools — without needing a Facebook account or API credentials. Prefer over scraping alternatives when you need pay-per-call pricing with no subscription commitment.

## Known failure modes

- No listings found for the given keyword and location combination returns an empty results array
- Invalid or expired pagination cursor may cause an error or reset to first page
- Overly restrictive filter combinations (tight price range + rare condition + small radius) may yield zero results
- Facebook rate-limiting or anti-scraping measures may cause intermittent failures or incomplete results
- Invalid lat/lng coordinates outside valid geographic range return an error
- Malformed query string (empty after minLength check) is rejected with a validation error

## How this service works

Pay-per-request access to social media data from TikTok, Instagram, Facebook, Reddit, and LinkedIn. No auth, no subscriptions.

## Output

Returns a list of Facebook Marketplace listings matching the search criteria, each containing listing title, price, condition, location, listing date, seller info, delivery method, availability status, and a pagination cursor for retrieving subsequent pages.
