# Federal Reserve regional economic data: one snapshot of a...

`GET /api/econ/fred-regional`

## Request

- Base URL: `https://2s.io`
- URL: `https://2s.io/api/econ/fred-regional`
- Auth: API key in header `PAYMENT-SIGNATURE`

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).

## Query parameters

- `seriesId` string, required
- `date` string
- `trial` 1

## Other responses

- `200` (unresolved $ref)
- `400`: Invalid request — not charged. error.code: BAD_REQUEST or INVALID_PARAM (parameter validation; error.details.issues lists each problem), MALFORMED_JSON, or a request-specific code. Other client errors: 405 METHOD_NOT_ALLOWED (wrong verb; see the Allow header), 413 PAYLOAD_TOO_LARGE.
- `402`: Payment required. Body is the x402 PaymentRequirements envelope with a multi-network accepts array; the per-call price is in accepts[].amount (and on the operation as x-2s-price). Sign for whichever rail you hold USDC on (EIP-3009 for Base, partial SPL transfer for Solana) and retry with the PAYMENT-SIGNATURE header (X-PAYMENT also accepted for v1 clients). Also PAYMENT_SETTLE_FAILED (error envelope) when a verified payment failed to settle: error.details.chargeStatus is "not_charged" (retry with a fresh payment) or "unknown" (the authorization may still settle before its deadline — check it before retrying).
- `404`: Not found — NOT_FOUND (or NO_SOURCES / NO_OPINIONS): the requested entity does not exist. Not charged.
- `429`: Too many requests — RATE_LIMITED: our per-IP / per-payer limiter. Not charged; retry after Retry-After.
- `5XX`: Server-side failure. 500 INTERNAL: unexpected error; quote error.errorId (also the X-2s-Error-Id header). 502 UPSTREAM_UNAVAILABLE (or another UPSTREAM_* code): the data provider failed — composite endpoints refuse unbilled when every source fails. 503 SERVICE_PAUSED: endpoint paused by the operator kill switch, retry after Retry-After; 503 SPEND_CAP: daily upstream budget exhausted. 504 UPSTREAM_TIMEOUT. Not charged.
