Try any of 3860 endpoints — live.
Pick an endpoint, load a working example, tweak the params, and send — no signup to try. Results render the way the data deserves; raw JSON, headers & code are one tab away.
The full listing by id or URL: title, the seller's full description, price and currency, the condition they graded it, the category path, every photo with its dimensions, the city it sits in with the city-level coordinates the site rounds to, when it was posted, whether it is available, pending or sold, how it can be delivered, and the seller as the public listing shows them: name, profile link, profile photo, the date they joined, and their 5-star rating with its count.
The number at the end of a Marketplace listing URL (facebook.com/marketplace/item/4511313592443983/ -> 4511313592443983). Every search row returns it as listing_id. A full URL is accepted too.
How hard to try for the seller. Facebook includes the seller on only about one in ten of its public listing responses, at random - the same listing carries it on one read and not the next. 1 (the default) returns whatever the first response had. Raise it and the listing is read again until the seller appears, up to this many reads, which makes the call slower. Measured on 9 listings: 0 of 9 had the seller on the first read, 3 of 9 within six. The answer always reports seller_available and seller_lookups, so you can see what it cost and whether it worked.

ReefAPI is one HTTP gateway to 632 live web-data APIs covering 3860 endpoints across 13 categories. Every endpoint answers with the same JSON envelope, so one integration reaches all of them. Each response reports what it cost and when the source was read.
No signup, no API key and no card are required to try an endpoint on this page. Anonymous calls run on a shared demo key, capped at 15 calls per hour per visitor. Pick an API, fill the parameters and the real response comes back from the live source, not from a canned sample. A free account lifts the cap and gives you 1,000 credits and your own key.
Browse every API in the catalog, read an endpoint's fields and example response in the docs, or see per-call credit costs on the pricing page.
