Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 nsf-awards-search-api-0b33bee3
```

Example prompt: Search NSF awards for the keyword 'quantum computing' and return up to 10 results with links to each award page.

## When to prefer this

Choose this endpoint when you need to search or discover NSF-funded research awards by keyword, topic, or organization, especially in automated agent workflows requiring programmatic access with per-call micropayment via x402/USDC on Base. Prefer over directly calling the NSF public API when you need a normalized, slim JSON response with UI links bundled in, or when you are operating in a context where x402 payment rails are already integrated.

## Known failure modes

- HTTP 402 if payment is not included — USDC payment on Base required
- Missing required 'keyword' query parameter returns a validation error
- No results returned if keyword or awardee name matches no NSF records
- Invalid ROR ID format may return empty or error response
- Rate limiting or server errors from upstream NSF API propagating as 5xx

## How this service works

Paid public-data feeds. Unpaid requests return HTTP 402. Prices are USDC on Base.

## Output

Returns a slim JSON object containing an array of NSF award records matching the query, each with award metadata and a uiLink to the NSF award page. The response includes a source path and a descriptive label indicating it is an NSF Award Search result.
