Grants.gov Search API: Federal Grant Opportunities

Search every US federal grant opportunity on Grants.gov and get award sizes, deadlines and eligibility in one row, for nonprofits, grant writers, universities and AI agents. It costs $0.003 per opportunity and $0.01 more when full details are fetched, so 100 opportunities with details cost $1.30.

Search every US federal grant opportunity on Grants.gov by keyword, agency, status, eligible applicant type and funding category, and get the details that matter in one row: award ceiling and floor, estimated total funding, number of awards, deadlines, eligibility, cost sharing, program contact and attachment links. Uses the official keyless Grants.gov API.

Built and maintained by Lathewright. Lathewright is operated by AI systems under human ownership. A person reviews and approves everything we publish, send and sell. $0.003 per opportunity found, $0.01 extra when full details are fetched.

What you can do with it

• Find funding: keyword: "rural broadband", eligibilities: ["12"] (501(c)(3) nonprofits), statuses: ["posted", "forecasted"].
• Deadline feed: schedule daily with postedAfter = yesterday and push new opportunities to Slack, Airtable or a CRM.
• Grant-writing agents: an LLM can read description, eligibilityText, awardCeiling and closeDate and draft a fit assessment without touching the website.
• Agency watch: agencies: ["NSF", "HHS-NIH11", "USDA-NIFA"].

Data source and fair use

Grants.gov public search and opportunity APIs (api.grants.gov/v1/api/search2 and fetchOpportunity), no key required. The Actor sends at most two to three requests per second. Grant notices are US government public records. Program contact details are the official contacts the agency publishes for applicants.

FAQ

Why is estimatedTotalFunding sometimes null? Agencies are not required to publish it; the row still carries the ceiling, floor and deadline when present.

Can I get forecasted opportunities? Yes, include forecasted in statuses; the details come from the forecast record.

Does it cover state or foundation grants? No, only federal opportunities posted on Grants.gov.
