# Endpoint reference

This reference is generated from the same OpenAPI document published for clients. Expand an endpoint for parameters, request schema, examples where supplied, response schemas and authentication requirements. Schemas describe data; the linked guides explain workflow decisions.

Base URL: `https://stratatcg.com/connector`. Paths below append to that base. Personal API keys authenticate the public card routes; OAuth access tokens authenticate only the environment-specific agent gateway. Browser session and internal administration routes are not third-party APIs.

Use JSON content type on JSON POSTs and a stable `Idempotency-Key` for each billable logical request. Read per-item state even after HTTP 200. [Authentication](./get-started.md), [OAuth](./oauth.md), [errors and retries](./errors-retries.md), [OpenAPI JSON](/connector/openapi.json).
