# SiteCheck Company Records – SBIR/STTR Government Grants Search

> SiteCheck Company Records – SBIR/STTR Government Grants Search is a paid API for AI agents from api.companyrecords-api.workers.dev, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-24).

## 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 sitecheck-company-records-sbir-sttr-government-grants-search-f580e034
```

Example prompt: Search SBIR.gov for small-business R&D grants related to 'battery technology' and show me the first page of results with full details — award amounts, company addresses, contract numbers, and whether any are woman-owned or HUBZone businesses.

## When to prefer this

Use this endpoint when you need to search the official US government SBIR/STTR award database by keyword and retrieve structured grant data including financials, company identifiers, and diversity flags. Prefer this over general web search when you need structured, machine-readable award data directly from the SBA's authoritative source. Ideal for competitive intelligence, grant research, vendor discovery, and market analysis of federally funded R&D.

## Known failure modes

- Missing required 'query' parameter returns an error
- Page number out of range (1-100) may return empty results or error
- SBIR.gov upstream unavailability causes fetch failures
- Low result counts for very niche keywords
- Enrichment from award pages may partially fail if individual award pages are slow or unavailable
- details parameter out of range (0-10) may cause validation error

## How this service works

Pay-per-call company registry, government, legal and B2B data tools for AI agents, from official registers and public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.

## Output

Returns a paginated JSON response (10 awards per page) with total result count and source URL. Each item includes award title, company name, agency, program (SBIR/STTR), phase, year, and award URL. For the top N results (configurable, default 5), additional enriched fields are included: award amount in USD, contract number, UEI, solicitation number, start/end dates, company address, and woman-owned/HUBZone flags. Also includes abstract excerpt and agency tracking number.
