## 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 script-master-labs-sbir-grants-search-api-7074ca2b
```

Example prompt: Search for SBIR grants related to 'autonomous vehicles' from DOD, phase 2 only, and return the top 10 results.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to U.S. SBIR/STTR federal grant data filtered by technology keyword, agency, and phase, especially in agentic workflows that use x402 micropayment settlement on Base. Prefer this over manual SBA portal searches when automating grant discovery, competitive research, or proposal preparation pipelines.

## Known failure modes

- Missing required 'keyword' parameter returns a 400 validation error
- Payment not settled in USDC on Base results in a 402 Payment Required response
- Invalid agency abbreviation may return empty results rather than an error
- Overly broad or common keywords may return noisy or truncated result sets
- Service unavailability on the hosted render.com instance may cause 503 errors

## 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

A list of SBIR/STTR grant records matching the keyword and optional filters, including award details, agency, phase, and recipient information sourced from U.S. federal grant data.
