How this service works
232 pay-per-call data APIs for AI agents: official statistics and economy (ECB, Fed, Eurostat, World Bank, SEC, BOE, INE), crypto prices and sentiment, Spanish public data, compliance (sanctions, VAT, IBAN, LEI), science, weather, web and developer tools and local AI text tools. Pay in USDC via x402.
Output
Returns a JSON object containing the search keyword, the since date, the data source attribution (USASpending.gov), and an array of matching contracts. Each contract includes: contract number, awarding agency name, awardee company name, contract start and end dates, total amount in USD, a description of the contract scope, and a direct link to the USASpending.gov award page.
Example use cases
AI contract competitive intelligence
“Find all US federal contracts related to 'artificial intelligence' awarded in the last year — I want to see who the awardees are, which agencies are spending, and how much each contract is worth.”
Vendor federal contract history
“Search for US government contracts awarded to 'Palantir' since 2022-01-01, up to 50 results, so I can see their federal revenue sources and which agencies they work with.”
Government cloud spending research
“Look up US federal contracts with 'cloud computing' in the description from the past 2 years — give me up to 30 results including the contract number, agency, awardee, and amount.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/us-federal-contracts?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
