Quarterly real GDP by US state from the Bureau of Economic Analysis (BEA) Regional accounts — all-industry total, in millions of chained (inflation-adjusted) dollars. Requires state (2-letter); optionally a specific year (defaults to the last 5 years). Returns the state name plus GDP observations (period like 2025Q2, real GDP in millions USD, unit), newest quarter first. Free, public-domain (BEA). Authoritative state economic-output data an LLM cannot recall — for economic research, regional analysis, and market sizing.
/api/gov/bea-gdpPAYMENT-SIGNATURE.The bea gdp API is a pay-per-call gov endpoint built for AI agents and autonomous software. Quarterly real GDP by US state from the Bureau of Economic Analysis (BEA) Regional accounts — all-industry total, in millions of chained (inflation-adjusted) dollars.
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 bea gdp data source for an agent tool-use loop, an MCP host, or a backend that needs gov data on demand without onboarding to yet another vendor portal.
