TickerLayer gives ChatGPT live and historical market data across crypto, forex, stocks, indices, ETFs, commodities, and government bond yields. Users can ask how any instrument is doing right now, pull OHLCV history between dates, discover valid symbols, check whether a market is open, and look up trading sessions and holiday calendars. All data is read-only, indicative, and non-exchange-sourced; the app never executes trades or gives investment advice. Requests run under the user's own TickerLayer account via OAuth, with the account's plan limits applying.
