US federal government spending awarded to a public company (sourced from USAspending). Pass ticker and optionally a from/to window (YYYY-MM-DD; defaults to ~2 years); returns each award with the recipient (and parent), awarding agency/sub-agency, obligated/outlayed/potential/total values in USD, action date, and period of performance. Use it to see how much federal money flows to a company. Data by Finnhub.
/api/stocks/gov-spendingPAYMENT-SIGNATURE.The gov spending API is a pay-per-call stocks endpoint built for AI agents and autonomous software. US federal government spending awarded to a public company (sourced from USAspending).
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in gov spending data source for an agent tool-use loop, an MCP host, or a backend that needs stocks data on demand without onboarding to yet another vendor portal.
