## 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 nih-reporter-grant-search-9c1069f7 -d '<json body>'
```

Example prompt: Can you search the NIH RePORTER grant database for federally funded research on Parkinson's disease and tell me which organizations received awards, which NIH institutes administered them, and what the grant titles and award IDs are?

## When to prefer this

Choose this endpoint when you need structured metadata about federally funded NIH biomedical research grants — especially for grant discovery, competitive landscape analysis, or identifying funding organizations and award IDs. Prefer it over general web search when you need structured, reliable grant-level data across all disease areas and disciplines. Best suited for agents that need programmatic access to NIH RePORTER data without scraping the NIH website directly.

## Known failure modes

- No matching grants found for very narrow or misspelled query terms
- Stale results if the NIH RePORTER snapshot is not current
- Overly broad queries returning too many results with insufficient filtering
- Grants outside the bounded snapshot date range may not be returned
- Malformed POST body or missing required fields returns a validation error

## How this service works

Search a bounded NIH RePORTER snapshot for federally funded biomedical research grants -- title, funded organization, administering NIH institute, award identifiers, and dates -- across every disease area and biomedical discipline, not one narrow field. Metadata only.

## Output

Returns metadata for matching NIH grant records including grant title, funded organization name, administering NIH institute, award identifiers, and relevant dates (e.g. project start/end). No full-text content or financial breakdowns — metadata only.
