Federal Reserve regional economic data: one snapshot of a FRED regional series across ALL its geographies (every U.S. state, county, or metro area) for a single period. Pass a regional series id (e.g. WIPCPI = per-capita personal income by state, or a state/county unemployment series) and get each region's name, FIPS region code, value, and per-region FRED series id, plus the group's units, frequency, and available date range. Add a date (YYYY-MM-DD) for a point-in-time cross-section; omit it for the latest. Authoritative St. Louis Fed (GeoFRED) data agents can't recite — per-state income, county unemployment, regional GDP — keyed by exact region codes. Free, public-domain. Companion to econ.fred (national series), econ.fred-categories (discover series ids), and census.demographics (ACS survey).
/api/econ/fred-regionalPAYMENT-SIGNATURE.The fred regional API is a pay-per-call econ endpoint built for AI agents and autonomous software. Federal Reserve regional economic data: one snapshot of a FRED regional series across ALL its geographies (every U.S.
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 fred regional data source for an agent tool-use loop, an MCP host, or a backend that needs econ data on demand without onboarding to yet another vendor portal.
