+# API Reference
+
+This page documents all of the API endpoints for each Druid service type.
+
+## Table of Contents
+ * [Coordinator](#coordinator)
+ * [Overlord](#overlord)
+ * [MiddleManager](#middlemanager)
+ * [Peon](#peon)
+ * [Broker](#broker)
+ * [Historical](#historical)
+
+## Common
+
+The following endpoints are supported by all nodes.
+
+### GET
+
+* `/status`
+
+Returns the Druid version, loaded extensions, memory used, total memory and
other useful information about the node.
+
+* `/health`
+
+An endpoint that always returns a boolean "true" value with a 200 OK response,
useful for automated health checks.
+
+* `/properties`
+
+Returns the current configuration properties of the node.
+
+## Coordinator
+
+HTTP Endpoints
+--------------
+
+The coordinator node exposes several HTTP endpoints for interactions.
+
+### GET
+
+#### Coordinator information
+
+* `/druid/coordinator/v1/leader`
+
+Returns the current leader coordinator of the cluster.
+
+* `/druid/coordinator/v1/isLeader`
+
+Returns a JSON object with field "leader", either true or false, indicating if
this server is the current leader
+coordinator of the cluster. In addition, returns HTTP 200 if the server is the
current leader and HTTP 404 if not.
+This is suitable for use as a load balancer status check if you only want the
active leader to be considered in-service
+at the load balancer.
+
+* `/druid/coordinator/v1/loadstatus`
+
+Returns the percentage of segments actually loaded in the cluster versus
segments that should be loaded in the cluster.
+
+ * `/druid/coordinator/v1/loadstatus?simple`
+
+Returns the number of segments left to load until segments that should be
loaded in the cluster are available for queries. This does not include
replication.
+
+* `/druid/coordinator/v1/loadstatus?full`
+
+Returns the number of segments left to load in each tier until segments that
should be loaded in the cluster are all available. This includes replication.
+
+* `/druid/coordinator/v1/loadqueue`
+
+Returns the ids of segments to load and drop for each historical node.
+
+* `/druid/coordinator/v1/loadqueue?simple`
+
+Returns the number of segments to load and drop, as well as the total segment
load and drop size in bytes for each historical node.
+
+* `/druid/coordinator/v1/loadqueue?full`
+
+Returns the serialized JSON of segments to load and drop for each historical
node.
+
+#### Metadata store information

+* `/druid/coordinator/v1/metadata/datasources`
+
+Returns a list of the names of enabled datasources in the cluster.
+
+* `/druid/coordinator/v1/metadata/datasources?includeDisabled`
+
+Returns a list of the names of enabled and disabled datasources in the cluster.
+
+* `/druid/coordinator/v1/metadata/datasources?full`
+
+Returns a list of all enabled datasources with all metadata about those
datasources as stored in the metadata store.
+
+* `/druid/coordinator/v1/metadata/datasources/{dataSourceName}`
+
+Returns full metadata for a datasource as stored in the metadata store.
+
+* `/druid/coordinator/v1/metadata/datasources/{dataSourceName}/segments`
+
+Returns a list of all segments for a datasource as stored in the metadata
store.
+
+* `/druid/coordinator/v1/metadata/datasources/{dataSourceName}/segments?full`
+
+Returns a list of all segments for a datasource with the full segment metadata
as stored in the metadata store.
+
+* POST `/druid/coordinator/v1/metadata/datasources/{dataSourceName}/segments`
+
+Returns a list of all segments, overlapping with any of given intervals, for
a datasource as stored in the metadata store. Request body is array of string
intervals like [interval1, interval2,...] for example
["2012-01-01T00:00:00.000/2012-01-03T00:00:00.000",
"2012-01-05T00:00:00.000/2012-01-07T00:00:00.000"]
+
+* POST
`/druid/coordinator/v1/metadata/datasources/{dataSourceName}/segments?full`
+
+Returns a list of all segments, overlapping with any of given intervals, for a
datasource with the full segment metadata as stored in the metadata store.
Request body is array of string intervals like [interval1, interval2,...] for
example ["2012-01-01T00:00:00.000/2012-01-03T00:00:00.000",
"2012-01-05T00:00:00.000/2012-01-07T00:00:00.000"]
+
+*
