## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability scriptmasterlabs-sbir-grants-search-api-72010a0b
```

Example prompt: Search for SBIR grants related to machine learning — show me up to 10 results from NIH, phase 1 only.

## When to prefer this

Use this endpoint when an agent or user needs to discover current federal SBIR or STTR grant opportunities filtered by technology keyword, specific agency (e.g. DOD, NIH, NASA, NSF, DOE), and phase. Ideal for startup founders, researchers, or grant writers seeking pay-per-use access without a subscription. Best suited for keyword-driven federal grant discovery rather than broad procurement or contract searches.

## Known failure modes

- Missing required keyword parameter returns validation error
- Payment not provided or invalid results in HTTP 402 response requiring x402 payment or API key
- Invalid agency abbreviation may return empty results
- Phase value outside allowed enum ('1' or '2') causes input validation failure
- Limit exceeding 25 or below 1 is rejected
- Service unavailable on free render hosting during cold start or downtime

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

Returns a list of SBIR/STTR grant opportunities matching the search criteria, including grant details such as agency, phase, title, and funding information, up to the requested limit (max 25).
