How this service works
Wallet-paid decision intelligence for finding live US federal funding opportunities.
Output
A JSON object containing an array of matched funding opportunities (each with title, fit score 0–100, days until deadline, and award ceiling in USD), plus metadata: the number of opportunities evaluated, total upstream hits, and search diagnostics including resolved terms, agency codes, and any empty-result reasons.
Example use cases
Nonprofit grant discovery for program staff
“Search for the top 5 federal grants that fit our food bank — we're a 501(c)(3) in rural Mississippi focused on food access and nutrition education, and I want to see what USDA or HHS opportunities are open right now.”
Small business federal funding search
“Find up to 8 federal funding opportunities for our small manufacturing company in Ohio — we do advanced composites and workforce upskilling, and I want to know which ones have the best fit score and how many days until the deadline.”
Research institute grant matching
“Pull the top 3 federal opportunities matching a university research center focused on quantum computing and AI safety — include any DARPA or NSF programs, and show me the award ceiling for each match.”
Technical details
Endpoint
POSThttps://3ak4wnwmvtcimaemr2xqt5wkc4.srv.us/v1/funding/matchWhen to prefer
Use this endpoint when you need to surface ranked, live US federal funding opportunities against a specific organizational or project profile. It is ideal for grant discovery workflows where fit scoring and deadline urgency matter, and where you want to filter by agency or eligibility type. Prefer this over general web search when you need structured, scored results with award ceiling data rather than raw listings.
Side effects
- Profile too vague or short — returns low fit scores or empty matches with emptyReason populated in diagnostics
- Requested agency not found — resolvedAgencyCode will be null and results may be broad
- Limit out of range (must be 1–10) — returns validation error
- Profile or keywords exceed character limits — request rejected with schema error
- Payment not completed or insufficient USDC balance — 402 Payment Required response
- No live opportunities match the profile — matches array is empty with diagnostic context
