}What you can build
Structured data for real applications. Here are some ideas.
Second-Hand Price Monitoring
Track asking prices for used electronics, furniture, and gear by zip code and radius. Combine price_min and price_max with condition filters to watch a specific segment of the market over time.
Marketplace Search Apps
Build a second-hand shopping interface with real listings, photos, condition, and fulfilment options. Search returns clean JSON, so there is no HTML parsing to maintain.
Seller Due Diligence
Check a counterparty before buying: items sold, follower count, rating summary, verification badges, and review text are one call away.
Inventory Reselling Leads
Surface underpriced second-hand listings matching your buying criteria, then enrich each candidate with detail and seller history.

Frequently asked questions
Not on the search page. OfferUp only exposes condition, post date, category, and fulfilment on its detail resolver, so filling them in for a full page of listings would take dozens of extra upstream requests behind one charge. Search returns them as null with hydrated set to false, and the item details endpoint returns the real values in one call.
Not at search time — that filter does not exist on OfferUp's search resolver. Sending it anyway would silently return every listing, so this API does not expose it. Use the fulfilment details on the item details endpoint to tell local pickup from shipping on listings you have already selected.
OfferUp falls back to the requesting server's own geography when no location is supplied, which means results change depending on which proxy handled the request. Requiring a zip code or coordinates makes a search reproducible. The geocode endpoint resolves a zip or place name to coordinates first.
No to both. OfferUp controls its own page size, ignores a limit on search, and never reports a total. The total_results field is always null — derive completeness from the listings themselves. On seller listings a limit is forwarded upstream, but the page is returned whole so no listing becomes unreachable, which means count can come back higher than the limit you asked for.
Just a Scrappa API key passed as an X-API-KEY header. No OfferUp account, no partner program, no OAuth. Sign up for free, get your key, and start querying listings immediately.
No. A request that fails upstream is never billed. A successful search that happens to match zero listings is a real answer and is billed normally.
Yes. Every Scrappa account gets 500 free credits per month with no credit card required. Test all OfferUp endpoints before committing to paid usage.
Scrappa charges $0.20 per 1,000 requests with no daily caps. All OfferUp endpoints cost the same. The free tier includes 500 credits per month to get started.
