# Futures price history

`GET /api/v2/futures/{root}/historical`

OHLCV history for a futures root. Returns the continuous front-month series by default, or a specific dated contract when 'expiration' (YYYY-MM) is supplied. Use period OR start/end, not both.

## Path parameters

- `root` string, required — Futures root symbol.

## Query parameters

- `period` string, nullable — 1d, 5d, 1mo, 3mo, 6mo, 1y, 2y, 5y, 10y, ytd, max
- `start` string, nullable — YYYY-MM-DD
- `end` string, nullable — YYYY-MM-DD
- `interval` string — 1m, 5m, 15m, 1h, 1d, 1wk, 1mo
- `expiration` string, nullable — Dated contract expiration month (YYYY-MM). Omit for continuous front-month.

## Response `200`

OHLCV bars for the continuous or dated futures series.

- EnvelopeFuturesHistoricalResponseV2
  - `data` FuturesHistoricalResponseV2, required
    - `root` string, required — Futures root symbol.
    - `contract` string, required — Contract series: 'continuous' (front-month) or 'dated'.
    - `expiration` string, nullable — Delivery month (YYYY-MM) for a dated contract; null for continuous.
    - `interval` string, required — Reporting interval.
    - `currency` string, nullable — Quote currency (ISO 4217).
    - `exchange` string, nullable — Listing exchange.
    - `timezone` string — Timezone identifier (IANA).
    - `data` FuturesHistoricalRowV2[] — OHLCV bars.
      - `date` string, required — Observation date (YYYY-MM-DD) or datetime (ISO 8601) for intraday.
      - `open` number, nullable — Period opening price.
      - `high` number, nullable — Period high price.
      - `low` number, nullable — Period low price.
      - `close` number, nullable — Period closing price.
      - `volume` integer, nullable — Period trading volume.
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
