Developer Tools No Auth Free & Open developer_tools

The Engine API is an HTTP API served by Docker Engine. It is the API the Docker client uses to communicate with the Engine, so everything the Docker client can do can be done with the API. Most of the client's commands map directly to API endpoints (e.g. `docker ps` is `GET /containers/json`). The notable exception is running containers, which consists of several API calls. # Errors The API uses standard HTTP status codes to indicate the success or failure of the API call.

GET Monitor events

Stream real-time events from the server. Various objects within Docker report events when something happens to them. Containers report these events: `attach`, `commit`, `copy`, `create`, `destroy`, `detach`, `die`, `exec_create`, `exec_detach`, `exec_start`, `export`, `health_status`, `kill`, `oom

Returns a list of networks. For details on the format, see [the network inspect endpoint](#operation/NetworkInspect). Note that it uses a different, smaller representation of a network than inspecting a single network. For example, the list of containers attached to the network is not propagated in

What can you build with Docker Engine API?

Docker Engine API is a Developer Tools API. Developers commonly use developer tools APIs for:

automating code review and quality checks
integrating CI/CD pipelines and build systems
managing feature flags and A/B tests
monitoring errors and application performance
generating and validating test data

No authentication required. This API is open — no signup or key needed. Ideal for quick prototypes and public-facing features. Docker Engine API is free to use, making it a low-risk choice to experiment with.
