Prices are intended for display only. For real-time trading prices, use the [Soft Attestation Quote](https://docs.ondo.finance/api-reference/attestations/request-a-soft-attestation-quote) API. We do not recommend using the price feeds as an oracle for these assets. An official oracle is in development and will be documented when available. For questions, contact [support@ondo.finance](mailto:support@ondo.finance). The `interval` parameter determines the bucket size for data points, while the `range` parameter determines how far back historically to look for price data. See below for valid interval/range pairs. Valid `interval`/`range` pairs: - 1min/1day *(rolling 24-hour period of open market data)* - 5min/1day - 15min/1day - 1hour/1month - 4hour/1month - 12hour/3month - 1day/3month - 1day/6month - 1day/1year - 1day/all *(all historical data)* For caching details on this endpoint, please see: [Endpoint Caching](https://docs.ondo.finance/api-reference/endpoint-caching). ## OpenAPI ````yaml /gm-be-api-spec.json get /v1/assets/{symbol}/prices/ohlc openapi: 3.0.4 info: title: GM Backend API description: An API spec for the Ondo GM Backend API. version: 1.0.0 servers: - url: https://api.gm.ondo.finance description: GM Backend API security: [] tags: - name: Attestations description: Get Mint and Redeem Attestations - name: Assets description: Get Asset Price Information - name: Tickers description: Get Ticker Information - name: Chains description: Get On Chain Data - name: Limits description: Get Trading Limits - name: Status description: Get Market and Trading Statuses paths: /v1/assets/{symbol}/prices/ohlc: get: tags: - Assets summary: Get OHLC (Open, High, Low, Close) Data for an Asset description: > This endpoint retrieves historical Open, High, Low, Close (OHLC) price data for both the primary market (on-chain token) and underlying market (off-chain stock) for a specified asset.
