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
Returns a JSON object with the search keyword, start date filter, data source attribution (USAspending.gov), and an array of contracts sorted by award amount descending. Each contract includes: contract ID, recipient name, awarding agency, start and end dates, a description of the work, the total award amount in USD, and a direct link to the USAspending.gov award page.
Example use cases

Technical details
Endpoint
POSThttps://api.vextorium.com/contratos-eeuu-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, ranked data on US federal government contract awards from the authoritative public source (USAspending.gov), especially for market research, competitive analysis, or identifying which companies are winning federal work in a given domain. Prefer this over general web search when you need structured fields (amounts, agencies, dates, recipients) rather than news articles or press releases about government spending.
Side effects
- No contracts found for obscure or misspelled keywords — returns empty contracts array
- USAspending.gov API unavailable or rate-limited — may return error or empty results
- Date format errors if 'desde' is not in YYYY-MM-DD format
- Limit out of range (must be 1-100) — may return validation error
- Very broad keywords may return noisy or loosely related results
