# Brand API reference

Use this reference with the [integration guide](https://docs.creatorgeo.ai/custom-ecommerce/integration/index.md). Requests target Brand API contract `2026-10` at `https://api.creatorgeo.ai/brand/2026-10`. Confirm that this contract is available for your integration before making requests. Each endpoint has a short request example in cURL, Python, Node.js, Ruby, Java, and Go. Set `DELIVERY_API_KEY` in your environment and replace the example article IDs with IDs from your responses. For change-feed examples, set `DELIVERY_CHANGE_CURSOR` to the `change_cursor` returned by the article list. Live request testing is disabled. Keep your delivery key on your server; never enter it into a documentation page.
