Facebook Research

Facebook research

Search Facebook Marketplace and look up public Facebook Page details — all as normalized JSON from the Crawlora API, no browser automation or logged-in session required.

When to use this skill

• "Find Marketplace listings for near ."
• "What's on the Marketplace browse feed for /?"
• "Get 's follower count / category / contact info."
• "Does this Facebook Page list a phone number or website?"
• Local-market price research or lead-gen sweeps of a Page's public About tab.

Setup (one-time)

• Get a free Crawlora API key (2,000 credits/mo, no card) at https://crawlora.net.
• Set CRAWLORA_API_KEY in the environment before running the helper.
• The helper reads CRAWLORA_API_KEY from the environment and sends requests to https://api.crawlora.net/api/v1. Missing/invalid key → 401.

How it works

1. Marketplace search / browse — GET /facebook/marketplace/search with a required location (Marketplace vanity slug) plus an optional query or category; omit both query and category to get the location's browse feed instead of a search. min_price, max_price, sort_by, days_since_listed, and condition only take effect alongside a query or category.
2. Page lookup — GET /facebook/{page} where page is a vanity name, handle, profile.php id, or full Facebook URL; returns name, follower/like counts, intro, category, business hours/price range, review count, and any public contact details on the Page's About tab.

Calling the API

# Marketplace search / browse:
scripts/crawlora.sh /facebook/marketplace/search location=chicago-il query="dining table" | jq '.'
scripts/crawlora.sh /facebook/marketplace/search location=chicago-il category=vehicles min_price=5000 | jq '.'

# Page lookup:
scripts/crawlora.sh /facebook/nike | jq '.'

Use scripts/crawlora.sh for all requests; it keeps the API key out of command-line arguments.

Endpoint reference

See reference/endpoints.md for both Facebook endpoints this skill uses.

Examples

• Local resale price check: /facebook/marketplace/search with location + query for an item, compare listed prices/conditions across the first page of results.
• Business lead enrichment: /facebook/{page} for a prospect's Facebook Page to pull follower count, category, and any public phone/email/website from the About tab before outreach.

Notes & limits

• Credits / pay-on-success: billed only on 2xx; free tier 2,000 credits/mo. Key at https://crawlora.net.
• Public data only — public Marketplace listings and public Page info; no login, no private content. Respect Facebook's terms.
• Security: key lives in CRAWLORA_API_KEY only — never hardcode, query-param, or commit it.
• Marketplace search is single-page only: Facebook's own further pagination requires a logged-in session and is out of scope — only the first page of server-rendered results is returned.
• property_rentals category is always filtered — it has its own listing page and ignores the min_price/max_price/sort_by/etc. filters the same way the plain browse feed does.
• Marketplace search can be slow — up to roughly a minute in the slowest case, since it retries past an intermittent upstream condition; priced accordingly.
