API Documentation

The ORATS API is organized around REST. Our API is designed to have predictable, resource-oriented URLs and to use HTTP response codes to indicate API success and errors. You can use our API to access options data in our database.

Getting started

To get started, purchase an API token through our website, then go to your dashboard to view your token and interact with the endpoints. To access live data, you'll need an active Tradier brokerage account. You can link your account to ORATS here.
