This reference covers the two REST APIs that the Daytona SDKs call. The Daytona API manages platform resources: sandboxes, images, snapshots, volumes, secrets, registries, organizations, projects, and API keys. The Toolbox API runs inside each sandbox and exposes its environment: processes, sessions, files, Git, language servers, and computer use.

Both APIs return errors as JSON with an error code, a message, and the error source. This reference is generated from the OpenAPI specification of each API.

| **Concept**               | **Description**                                                                                     |
| ------------------------- | --------------------------------------------------------------------------------------------------- |
| **Daytona API**           | The API for managing sandboxes and other platform resources.                                        |
| **Toolbox API**           | The API served inside a running sandbox for processes, files, Git, language servers, and more.      |
| **Project API key**       | The credential for workload operations, scoped to one project and limited to the permissions set at creation. |
| **Proxy**                 | The regional service that authenticates Toolbox API requests and routes them to the sandbox.        |
| **Toolbox proxy URL**     | The base URL of a sandbox's Toolbox API, returned in the `toolbox_proxy_url` field of the [sandbox](/docs/sandboxes#get-a-sandbox). Examples write it as `{toolboxProxyUrl}`, followed by the sandbox ID. |
| **Sandbox daemon**        | The agent inside each sandbox that serves the Toolbox API.                                          |
| **OpenAPI specification** | The machine-readable definition of each API, available for download below.                          |

## OpenAPI specifications [#openapi-specifications]

Each API has an OpenAPI 3.1 specification in JSON format. A specification lists every operation with its path, parameters, request and response schemas, and error responses. The Daytona API specification also names the permission that each operation requires. Use a specification to generate a client in your language or to import the API into an HTTP client.
