The Dataerai REST API gives you programmatic access to the platform — organizations, projects, collections, assets and their content, datasets, transfers, permissions, groups, allocations, and grants. The pages in this section are generated from the API's OpenAPI specification, and each endpoint has an interactive playground you can call from your browser. ## Base URL The API is served by your Dataerai deployment, with endpoints under `/api`. Use your deployment's host: ``` https:///api ``` Don't hardcode a host in shared code — the CLI and SDKs use a `DATAERAI_SERVER` setting (see the [CLI overview](/cli/overview)), and the API playground lets you set the server. ## Requests and responses * Requests and responses use `application/json`. * List endpoints are **paginated** — most page through results with the `page` and `page_size` query parameters and return the total count and next/previous links in the response body. Check each endpoint's page for its exact parameters. * Authentication is required for most endpoints — see [Authentication](/api-reference/authentication). ## OpenAPI specification The reference in this section is generated from the API's OpenAPI specification, published alongside these docs at [`openapi.yaml`](/api-reference/openapi.yaml). You can feed that file to your own code generator or HTTP client. ## Prefer a client? For uploads, downloads, and metadata, the [CLI](/cli/overview) and [SDKs](/sdks/python) handle authentication, multipart transfers, and resumes for you. Use the REST API directly when you need full control or are integrating another system. ## Next steps How to authenticate your API requests.
