+## API
+
+[zag-agent][agent] uses the UDP API.
+
+### UDP
+
+The primary protocol for recording metrics is over UDP. Each daemon is running a UDP
+server on `options.host`.
+
+The data should be newline-delimited lines of the form:
+
+    <type>:<key>=<value>
+
+where
+
+  * `type`  - `counter` or `histogram`.
+  * `key`   - `[>| \w/._()+:-]+`
+  * `value` - Number. Positive or negative, integer or decimal.
+
+### HTTP
+#### `POST /api/metrics`
+
+The POST body should be in the same format as the UDP data. The points are
+recorded as the arrive, so the client can just keep sending data down a
+single connection instead of making repeated requests.
