Give grant workflows asource of truth.

Genuine Good Grants API turns current Grants.gov public records into structured search, official detail, transparent mission-fit signals, sourced briefs, and deterministic shortlist checks. It is built for x402-compatible agents and software that needs useful grant data without an account or an API-key dance.

Useful enough to automate. Honest enough to verify.

One contract.

Five focused tools share one account-free x402 contract: search, detail, fit, brief, and shortlist preflight.

Sources stay attached.

Results preserve official Grants.gov links, normalized fields, dates, provenance, and the questions a human still needs to check.

Pay for the call.

Each successful tool call is $5 USDC on Base. Repeated workflows can use a non-renewing $15 pass for 30 days or 1,000 calls.

01 / DISCOVER

Read the live terms first.

Call any paid route without a payment header. The API returns HTTP 402 with the exact Base USDC terms for that request.

Open the x402 manifest
02 / AUTHORIZE

Let x402 handle payment.

Use an x402-compatible EVM client with USDC on Base, then retry the identical request with the signed payment header.

const response = await paidFetch(
  "https://genuinegood.online/v1/grants/search",
  {
    method: "POST",
    headers: { "content-type": "application/json" },
    body: JSON.stringify({ keyword: "rural clean water", rows: 5 }),
  },
);
03 / VERIFY

Keep the evidence.

Use the returned structured data, official notice link, and payment receipt together. A fit signal is research support, not an award prediction.

Inspect the sample. Then make one useful call.

See the output free, bring one to five opportunity IDs or a search question, and pay only when the API returns the tool you asked for.

Important limit. Genuine Good Grants is independent of Grants.gov and every U.S. agency. The API is a discovery aid; verify the complete official notice before acting.
