# Latest benchmark commodity price with the prior value + %...

`GET /api/econ/commodity`

## Request

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

Latest benchmark commodity price with the prior value + % change. Pass commodity for one, or omit for all. Commodities: wti, brent, natural-gas, gasoline, diesel, heating-oil, propane, copper, aluminum, corn, wheat, sugar — i.e. crude oil (WTI + Brent), natural gas, gasoline, diesel, heating oil, propane, gold, copper, aluminum, corn, wheat, sugar. Each result names the FRED series ID + unit ($/barrel, $/gallon, $/troy oz, $/metric ton...). Daily benchmarks report a daily date; global-price series are monthly. Source: EIA / LBMA / IMF via FRED (St. Louis Fed).

## Query parameters

- `commodity` 'wti' | 'brent' | 'natural-gas' | 'gasoline' | 'diesel' | 'heating-oil' | 'propane' | 'copper' | 'aluminum' | 'corn' | 'wheat' | 'sugar'

## 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.
