# Agent HTTP API

The Consul agent is capable of running an HTTP server that
exposes various API's in a RESTful manner. These API's can
be used to both query the service catalog, as well as to
register new services.

The URLs are also versioned to allow for changes in the API.
The current URLs supported are:

* /v1/catalog/register : Registers a new service
* /v1/catalog/deregister : Deregisters a service or node
* /v1/catalog/datacenters : Lists known datacenters
* /v1/catalog/nodes : Lists nodes in a given DC
* /v1/catalog/services : Lists services in a given DC
