How this service works
The insurance booth for AI agents, with Mini's Agent Supply Store on the side of the road. One hundred checkpoints: pre-transaction safety lanes (honeypot, approval-risk, rug-score, receipt-check, tx-dryrun, permit-scan, airdrop-verdict, deployer-history, wallet-watch, secret-scan at $0.02 USDC per call; the protection tier — /contract-check, /approval-screen, /tx-plain-english, /honeypot-check, /tx-simulate, /redteam, /skill-scan, /verdict, /egress-audit, /tool-gate, /airlock, /repo-scan, /prove, /task-scope — at $0.10; the one-call /shield don't-get-rugged screen at $0.25; the full /preflight bundle at $0.05), bounty intel (bounties, fresh, verdicts, deadlines, sweepstakes, opportunities) at $0.02 USDC per call, trader intel (/prices and /quant at $0.02; /enrich and /token-check at $0.05; /contract-check and /honeypot-check at $0.10; /sec-facts at $0.05), market intel (/markets and /search at $0.05; /grants at $0.02), DeFi intel (/yields and /new-pairs at $0.05; /gas and /defi at $0.02), AI intel (/models at $0.02), agent-ops intel (/prompt-cost, /model-picks, /rpc-speed, /terms-tldr, /scrape, /gigs, /retry-verify, /idempotency, /verify-independent at $0.02; /site-watch, /wallet-check, /code-run, /regulatory-pack, /sage, /cron-watch, /caveat-check, /tripwire, /escrow, /trust, /bridge-fees, /dao-votes, /dev-activity, /dex-arb, /dydx-perps, /funding-rates, /gas-predict, /hack-tracker, /long-short-ratio, /lp-yields, /mev-scan, /open-interest, /perp-basis, /polymarket-odds, /rwa-watch, /sentiment, /stablecoin-flows, /tokenomics, /top-movers, /whale-watch, and /yield-stable at $0.05; /approval-screen, /tx-plain-english, /tx-simulate, and /task-scope at $0.10; /scam-scan deep scan at $5.00 or 30-day subscription at $30.00), supply store (/road-pack combo meal at $0.05; curated datasets, the /audit-prep pre-audit review, and the /prove-state symbolic-execution run at $1.00; the /audit AI-agent audit at $25.00). Every lane answers before money moves — heuristic verdicts, not audits. Don't get rugged.
Output
Returns a JSON object with the searched keyword, a count of matching opportunities, and a list of federal grant records each containing the opportunity title, agency name, grant number, close date, award ceiling, and a URL to the full listing on Grants.gov. Data is sourced live from Grants.gov.
Example use cases
Nonprofit renewable energy funding search
“Search for currently posted federal grants related to 'solar energy' — I need the agency names, close dates, and maximum award amounts so I can see which ones to apply for.”
Startup finding AI research grants
“Look up open federal grant opportunities with the keyword 'artificial intelligence' and tell me which agencies are offering them and when they close.”
Grant deadline tracking for a specific agency
“Can you find posted federal grant opportunities from NASA using the keyword 'space technology'? I want to see award ceilings and close dates.”
Technical details
Endpoint
GEThttps://mini-tollbooth.onrender.com/grants?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to search live, real-time federal grant opportunities from Grants.gov by keyword, optionally filtered by agency or status. Prefer it over static grant databases when freshness matters. It costs only $0.02 USDC per call and is ideal for agents that need to discover funding opportunities programmatically without scraping Grants.gov directly.
Side effects
- Missing required 'keyword' query parameter returns an error
- No matching opportunities returns an empty list with count 0
- Grants.gov upstream outage may cause stale or unavailable data
- Invalid 'status' enum value may return unexpected results or an error
- Payment of $0.02 USDC required per call; unpaid requests are rejected with 402
