# HTTP API

EMQX Edge provides a set of HTTP APIs for integration with external systems. These APIs allow you to:

- Query broker statistics
- Retrieve client connection information
- View topic subscription details
- Restart the broker using a new configuration file
- Managing multi-channel bridging

By default, the HTTP API service listens on port `8081`, which can be changed in the configuration file at `etc/nanomq.conf`.

> All API endpoints are prefixed with `/api/v4`.

Currently, EMQX Edge supports a single version of the HTTP API. Refer to the following link for detailed API documentation:
