How this service works
Find new or changed U.S. federal grants for a maintained scope. Use scope, as_of, window_days, event_limit, and continuation cursor inputs. Receive JSON with events, changed fields, deadline risks, award-value changes, dataset status, evidence URLs, and next_request.
Output
A JSON object containing categorized grant change events — new grant listings, modified fields (e.g. award ceiling, eligibility), deadline risk flags, and award status changes — each with official Grants.gov evidence links. Also includes a cursor for paginating through additional results.
Example use cases
Weekly grant change digest for nonprofits
“Pull all new grants, deadline changes, and award modifications in the 'education and workforce development' scope over the past 7 days as of now, limit to 30 events, so I can brief my grants team Monday morning.”
Deadline risk monitoring for research office
“Check for any upcoming deadline risks or last-minute changes in the 'biomedical research' grant scope over the past 3 days as of right now — start from the beginning and give me up to 20 events.”
Paginated audit of grant award changes
“Resume my grant change audit for 'small business innovation' from cursor 42:1500 as of 2024-06-01T00:00:00Z, window of 30 days, and return up to 100 events ending at snapshot 9900.”
Technical details
Endpoint
POSThttps://grant-search.krimskrams.xyz/v1/change-intelligenceWhen to prefer
Use this endpoint when you need to detect *changes* in the federal grant landscape — new grants, modified fields, shifting deadlines, or award updates — rather than just searching current listings. It is ideal for monitoring workflows, weekly digests, and compliance tracking where knowing *what changed* and *when* is more important than a one-time search. Prefer sibling search endpoints for discovering current grants from scratch.
Side effects
- Invalid as_of datetime format returns 422 validation error
- Cursor format mismatch (not 'start' or 'N:N' pattern) causes 422
- Scope string exceeding 100 characters rejected
- event_limit outside 1–100 range rejected
- No changes found within window returns empty events array
- Upstream Grants.gov snapshot unavailable may return 503 or stale data
