Once you have a scoped API key, you're ready to call the API. The complete, interactive API reference — every endpoint, its parameters, and response shapes — is published in-app.
Open the API documentation from your workspace (the developer/API docs link) to browse and try endpoints. Authenticate your requests with the Authorization: Bearer ariyes_… header described in API overview and authentication, and start with a read-scoped key while you're testing so a mistake can't change data.
