POST /api/grantsgov/opportunities/search
Price: 10 credits
Search US federal funding opportunities by keyword, lifecycle stage, funding instrument, applicant eligibility, funding-activity category, agency, posting and closing windows, and cost-sharing requirement. Returns a card per opportunity with its UUID.
Leaving `statuses` empty gives the source's own default of forecasted plus open opportunities, so pass `closed` or `archived` explicitly to reach anything already past its deadline. `closing_within_days` only narrows opportunities that are still open. Take `opportunity_id` from a card and call grantsgov/opportunities for the description, eligibility detail and application documents. `agencies` takes the grants.gov agency code, not the readable agency name a result carries, and a code in the wrong case matches nothing rather than erroring, so prefer `query` when the code is unknown.

A URN with the wrong prefix is the most common cause.408 — The request ran past its time limit Raise `timeout` in the request body, up to the maximum this endpoint documents. Lowering `count` or turning off the `with_*` flags also helps, because less work finishes sooner.412 — The entity was not found, or a precondition failed Retrying will not help: either the entity does not exist, or the input points at a different one.429 — Too many requests: a rate limit or a usage window is exhausted When the response carries an X-Retry-After header, wait that many seconds and retry: the same number is in the body as `detail.retry_after`, and the limit clears once that window passes. The message in the body names the limit that was hit.500 — Something broke on our side Retrying will not help. If it keeps happening, send us the X-Request-ID from the response headers.529 — Rate limit reached, or the endpoint is overloaded Wait at least 30 seconds, then retry.X-Error — Error message text (present only on error)X-Request-ID — Unique request identifierX-Execution-Time — Execution time in secondsX-Result-Count — How many records the body carries. 0 means an empty result, which is a normal answer and not by itself an error. A non-zero count can come back together with X-Error when the failure happened partway through — read this header and X-Error independently.X-Total-Available-Results — How many records exist for this query, when the endpoint can say. On a `dry_run` request this is the answer and the body is empty. It saturates: the endpoint's documented maximum means 'at least that many', any smaller number is exact.X-Warning — Present when the request body carried keys this endpoint does not document. They were ignored, so any filter you meant to apply through them did not apply. Check the spelling against this schema and retry.X-Retry-After — Seconds to wait before retrying. Present only on 429.
