# Biomedical Grant Search

> Biomedical Grant Search is a paid API for AI agents from biomedical-grants.use.x402atlas.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Search NIH-funded research projects by keyword, fiscal year, institute, state, organization, activity code, or award size, returning grant details including investigators, funding amounts, and dates.

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 biomedical-grant-search-59d2a77f
```

Example prompt: Search NIH grants for projects on mRNA vaccine delivery, filtered to SBIR/STTR mechanism, fiscal years 2023 and 2024, and show me the top 20 results sorted by award amount.

## When to prefer this

Use this endpoint when you need to search NIH-funded research grants by topic keywords with flexible filtering — especially when you want to identify funded investigators, compare award sizes, find SBIR/STTR small-business recipients, or scope out NIH funding in a specific institute, state, or organization. Prefer this over the Biomedical Funding Trend endpoint when you need individual grant-level details rather than aggregate year-over-year totals, and over the New Awards Feed when you want historical search rather than recent additions.

## Known failure modes

- Missing required 'query' parameter returns a 400 validation error
- Overly broad or empty keyword query may return irrelevant or too many results
- Fiscal year or institute abbreviation typo returns zero results
- Requesting pages beyond available results returns empty awards array
- Rate limiting or payment failure (x402) returns 402 Payment Required
- NIH RePORTER data lag may mean very recent awards are not yet indexed

## How this service works

NIH-funded project search — find grants by words in the title, abstract or research terms, filtered by fiscal year, NIH institute, organisation, state, activity code, SBIR/STTR mechanism or award size, with the fiscal-year award amount, investigators, organisation and dates for each. Use to see who NIH funds on a topic, how much, and which small companies.

## Output

Returns a paginated list of NIH grant awards matching the query, each including the project title, abstract excerpt, fiscal-year award amount in USD, principal investigator name(s), funded organization name and state, NIH institute, activity code, grant dates, and total count of matching results. Also includes metadata such as the query parameters used, data source, and as-of date.
