## How to call it through Zero

## When to prefer this

Use this endpoint when you need to search US federal government contract award data by keyword or topic, especially for market research, competitive intelligence, vendor due diligence, or government spending analysis. It directly wraps USASpending.gov public data with a clean pay-per-call API, making it ideal for agents that need on-demand procurement lookups without managing API keys or handling government data formats. Prefer this over manually scraping USASpending.gov or building a custom integration.

## Known failure modes

- No contracts found for the given keyword — returns an empty contracts array
- Invalid date format for 'since' parameter — expects YYYY-MM-DD
- Limit out of range (must be 1–100) — may return an error or default to 10
- Search term too broad or too narrow — may return irrelevant or zero results
- Upstream USASpending.gov data unavailable — may return an error or stale data

## How this service works

US federal government contracts by keyword (USAspending): recipient, amount, awarding agency, dates and description, largest first. For public-sector market research and competitor analysis.

## Output
