## When to prefer this

Choose this endpoint when you need structured federal spending data from USAspending.gov without building a direct government API integration. Ideal for B2G sales intelligence, vendor due diligence on government revenue streams, competitive landscape research in federally-funded sectors, or grant opportunity discovery. Prefer this over generic web search when you need structured, filterable award records with amounts, agencies, and NAICS codes.

## Known failure modes

- No results returned if keyword is too niche or misspelled
- USAspending.gov API downtime causes upstream errors
- 'days' parameter outside 1-3650 range returns validation error
- 'limit' outside 1-100 range returns validation error
- 'award_type' values other than 'contracts', 'grants', or 'loans' may be rejected
- Recipient name fuzzy matching may miss exact legal entity names

## How this service works

## Output

A list of federal award records from USAspending.gov, each containing the recipient name, total award amount in USD, awarding agency, award start and end dates, place of performance, NAICS code, award type, and a description of the work or purpose of the award.
