All endpoints are served from https://api.marketdata.app/v1 and return JSON (or CSV) responses. Most endpoints require only a ticker symbol as a path parameter. Requests are authenticated with a Bearer token generated in the Market Data dashboard. Coverage spans stock candles and quotes (single and bulk), corporate earnings and news, full options chains with per-contract quotes, expirations, strikes and OCC symbol lookup, index candles and quotes, and market open/closed status. Note that Market Data may return HTTP 203 Non-Authoritative Information (instead of 200 OK) when a response is served from its caching tier; clients must treat 203 as success.\n\nContact Support:\n
