Example prompt: Find me NIH-funded research grants related to Alzheimer's disease from fiscal year 2022, especially any awarded to universities in California — I want the project titles, award amounts, PI names, and abstracts.

## When to prefer this

Use this endpoint when you need structured, authoritative NIH grant data including funding amounts, PI details, and project abstracts. Ideal for research discovery, competitive landscape analysis, academic funding lookups, or identifying researchers in a specific biomedical domain. Prefer this over general web search when you need machine-readable, filterable NIH grant records.

## Known failure modes

- No grants found for the specified query or filters — empty result set returned
- Invalid fiscal year format causes a bad request error
- Institution name misspelling results in no matches
- Payment of 0.005 USDC not fulfilled — 402 Payment Required error
- Rate limiting if too many requests are made in quick succession
