post/sam-gov/v1/search1 credit

Search every US federal contract opportunity by phrase — the demand side of a $700bn/year buyer. Each hit carries the response deadline, the buying department and office, the notice type (is this a heads-up, a live RFP, or an award?) and a 250-character preview of the solicitation text. Pair with `active_only=true` for things you can still bid on, or with notice type 'a' to see who won what.

What you can run here, without an account

ReefAPI is one HTTP gateway to 438 live web-data APIs covering 2778 endpoints across 14 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.
