This is the core underlying options data for many analytics. Although this data streams to Amberdata every 100ms this endpoint returns the first observation for each instrument in 1-minute, 1-hour or 1-day intervals. Note: Due to the density of data historical date ranges are limited to 60x 1-minute or 24x 1 hour intervals, per call. If no date range is passed, the most recent option chain will be returned. ## OpenAPI ````yaml get /analytics/volatility/level-1-quotes openapi: 3.1.0 info: title: derivatives-api version: '2' servers: - url: https://api.amberdata.com/markets/derivatives security: - sec0: [] paths: /analytics/volatility/level-1-quotes: get: summary: Level 1 Quotes description: >- This endpoint returns the Level 1 option chain with associated volatilities, greeks and underlying prices.
