Endpoint
GEThttps://x402-data-api-x6da.onrender.com/v1/gov/spending?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically query official U.S. federal government spending data — contracts, grants, loans, direct payments, or IDVs — from USASpending.gov via a pay-per-call API. Prefer this over manual USASpending.gov searches when you need machine-readable results for agent workflows, and over general web search when you require structured, authoritative government data. Best suited for research, compliance, procurement intelligence, and policy analysis tasks.
Side effects
- No results returned if agency name is misspelled or not an exact top-tier agency name
- Invalid award_type enum value causes validation error
- Date format must match expected string format or query may fail
- max_results not respected if too large or unsupported
- Payment failure via x402 if USDC balance is insufficient on Solana
- Rate limiting or timeout if the underlying USASpending.gov API is slow or unavailable
