# Get open interest history (Deprecated)

`GET /v1/openinterest/{symbol}`

## Request

- Base URL: `https://api.0xarchive.io`
- URL: `https://api.0xarchive.io/v1/openinterest/{symbol}`
- Auth: API key in header `X-API-Key`

> **Deprecated.**

**Deprecated:** use `/v1/hyperliquid/openinterest/{symbol}`, which serves the same Hyperliquid data. Responses carry `Deprecation: true` and `Link: </v1/hyperliquid/>; rel="successor-version"`. No removal date is set.

Get historical open interest data with associated market context (mark price, oracle price, volume, etc.).

## Path parameters

- `symbol` string, required

## Query parameters

- `start` union: An instant: Unix milliseconds, or an RFC 3339 string such as `2026-01-01T00:00:00Z` (encode a `+` offset as `%2B`). An unparsable value answers 400 `invalid_time_range`.
  - integer: Unix milliseconds.
  - string, date-time: RFC 3339 instant.
- `end` union: An instant: Unix milliseconds, or an RFC 3339 string such as `2026-01-01T00:00:00Z` (encode a `+` offset as `%2B`). An unparsable value answers 400 `invalid_time_range`.
  - integer: Unix milliseconds.
  - string, date-time: RFC 3339 instant.
- `cursor` string
- `limit` integer

## Response `200`

Open interest data

- ApiResponseOpenInterestArray
  - `success` boolean
  - `data` OpenInterest[]
    - `symbol` string, required: Trading pair symbol
    - `coin` string, required: Trading pair symbol (deprecated, use symbol instead)
    - `timestamp` string, date-time, required: Snapshot timestamp (UTC)
    - `open_interest` string, required: Total open interest in contracts
    - `mark_price` string, nullable: Mark price used for liquidations
    - `oracle_price` string, nullable: Oracle price from external feed
    - `day_ntl_volume` string, nullable: 24-hour notional volume
    - `prev_day_price` string, nullable: Price 24 hours ago
    - `mid_price` string, nullable: Current mid price
    - `impact_bid_price` string, nullable: Impact bid price for liquidations
    - `impact_ask_price` string, nullable: Impact ask price for liquidations
  - `meta` ResponseMeta: Response metadata. Every 2xx JSON response carries `meta.request_id`; list payloads add `count`; cursor-paged routes add `has_more` and, when another page follows, `next_cursor`; per-symbol routes add `symbol` and `venue`. Fields that do not apply to a route are omitted.
    - `count` integer: Number of records returned
    - `has_more` boolean: Cursor-paged routes: whether another page follows. `next_cursor` is present exactly when this is `true`. A final page can be empty when the previous page was exactly full; `has_more` is `false` on it.
    - `next_cursor` string: Opaque cursor for the next page, present exactly when `has_more` is `true`. Pass it back unchanged as `cursor` with the same filters. Do not parse or construct it.
    - `request_id` string, uuid, required: Unique request ID for support
    - `symbol` string: Per-symbol routes: the canonical public symbol the response describes (for example `BTC`, `xyz:TSLA`, `HYPE-USDC`, `#0`).
    - `venue` 'hyperliquid' | 'hip3' | 'hip4' | 'spot' | 'lighter' | 'rh-lighter': Per-symbol routes: the venue the response describes.
    - `coverage_from` string, date-time: Earliest coverage for the requested symbol and data type. Present only when the requested window ends before coverage begins.
    - `notice` string: Human-readable advisory about the response. Used when the requested window ends before coverage begins for the symbol, and on CVD responses that are one page of several; may carry other advisories in future.
    - `finalized_through` string, date-time: Two-tier datasets (Lighter trades): data at or before this instant is final; later data is preliminary.
    - `requested_end` string, date-time, nullable: The `end` the request asked for, echoed when it was clamped to `finalized_through`.
    - `clamped_to` string, date-time, nullable: The boundary the request's `end` was clamped to, when clamping occurred.
    - `preliminary_row_count` integer, nullable: Number of preliminary rows in this response, on routes that intentionally serve preliminary data (Lighter `/recent`).

## Other responses

- `400`: Invalid request: a parameter, symbol, interval, cursor or time range failed validation. See `error_code`.
- `401`: Authentication required: the API key is missing or invalid.
- `403`: The request is outside the plan's history window or per-request span, or the key is not allowed to make it.
- `429`: Rate limit, concurrency limit or monthly credits exceeded. See `error_code`.
- `default`: Any other error. The body is an `ErrorResponse`; branch on `error_code`. A 503 (`upstream_unavailable`) carries `Retry-After`.
