This document describes the PiKVM API. Since the system consists of microservices, here is a common API with a common entry point provided by Nginx. The below examples use curl and websocat with the -k option disables SSL certificate verification, since the self-signed certificateis are used in the default installation.
+
There is a third-party library for using the PiKVM API. Please note that this is an unofficial library, so use it carefully.
+
+
Authentication
+
All APIs are restricted to authentication. To make requests, you either need to auth each request individually, or get a token and pass it as a cookie with each request.
+
With enabled 2FA, you will need to add the one-time code to the password without spaces. That is, if the password is foobar and the code is 123456, then you need to use foobar123456 as the password.
+
The code can be generated using any TOTP library, for example in Python:
+
import requests
+import pyotp
+
+user = "admin"
+passwd = "admin"
+secret = "3OBBOGSJRYRBZH35PGXURM4CMWTH3WSU" # Can be found in /etc/kvmd/totp.secret
+
+print(requests.get(
+ url="https://pikvm/api/info",
+ verify=False, # For self-signed SSL certificate
+ headers={
+ "X-KVMD-User": user,
+ "X-KVMD-Passwd": passwd + pyotp.TOTP(secret).now(),
+ },
+).text)
+
+
Since in the borderline case of the 2FA code lifetime, the code may be invalid,
+it makes sense to either handle error 403 by repeating the request in seconds.
+
A more correct way is to combine this method and check the remaining lifetime
+and postpone the request if there is a second or so left. You can find out how much
+time is left in this way:
+
totp = pyotp.TOTP(secret)
+now = int(time.time())
+remaining = now - (now % totp.interval)
+
+
Single-request authentication
+
There are two options here:
+
+-
+
Using X-headers. Just pass X-KVMD-User and X-KVMD-Passwd with the request:
+$ curl -k -H X-KVMD-User:admin -H X-KVMD-Passwd:admin https://<pikvm-ip>/api/auth/check
+
+-
+
Using HTTP Basic Auth. Please note: contrary to the standard, this method DOES NOT use the WWW-Authenticate header. HTTP Basic Auth in this implementation is intended only for compatibility with other systems, such as Prometheus.
+$ curl -k -u admin:admin https://<pikvm-ip>/api/auth/check
+
+
+
Session-based cookie auth
+
+-
+
Get the access token for the user using POST /api/auth/login:
+$ curl -k -v -X POST --data user=admin --data passwd=admin https://pikvm/api/auth/login
+...
+< Set-Cookie: auth_token=796cb83b11de4fcb749bc1bad14a91fb06dede84672b2f847fef1e988e6900de; Path=/
+...
+
On success the cookie auth_token will be received with 200 OK. On invalid user or password you will get 403 Forbidden.
+
+-
+
The handle GET /api/auth/check can be used for check the auth status. Return of 200 OK will signal that user is authenticated. If the token or any of the single-request auth methods are missing, 401 Unauthorized will be returned. In case of incorrect credentials or token, 403 Forbidden will be returned.
+
+-
+
The handle POST /api/auth/logout can be used to invalidate session token. The response codes will be similar to the previous handle.
+
+
+
+
You can submit PiKVM credentials from another site and go directly to the KVM page by passing the redirect parameter as follows:
+
<html>
+<body>
+ <form method="POST" action="https://pikvm/api/auth/login">
+ <input name="user" value="admin">
+ <input name="passwd" value="admin">
+ <input name="expire" value="0">
+ <input name="redirect" value="/kvm/"> <!-- Available since KVMD 4.108 -->
+ <button type="submit">Open PiKVM</button>
+ </form>
+</body>
+<html>
+
+
+
WebSocket events
+
Most of the data during the user's work with PiKVM is transmitted over WebSocket. This includes mouse events, keyboard input, and changing the state of the various subsystems (such as ATX and Mass Storage Drive). Each event type will be described in the corresponding paragraph for its component. When connecting via WebSocket, the client receives current states as separate events. Then, as the states change, it will receive new events.
+
In a normal situation, opening a socket session triggers the video streamer to start. The streamer works as long as there is at least one client connected via WebSocket. After the last connection is closed and the client timeout expires, the streamer will also be terminated.
+
It is possible create a session that will not start the streamer and will not be counted when counting clients to stop the streamer. To do this, use the URL parameter stream=0:
+
$ websocat -k wss://<pikvm-ip>/api/ws?stream=0 -H X-KVMD-User:admin -H X-KVMD-Passwd:admin
+

+{"event_type": "loop", "event": {}}
+
+
After connecting the client receives a bundle of states of all KVMD subsystems. After the batch is completed, it sends a loop event, which means that the websocket has entered event loop mode. Now it will send new states and respond to client's requests.
+
Another type of event is ping, which can be sent by the client: {"event_type": "ping", "event": {}}. If the server is running, it will respond with pong: {"event_type": "pong", "event": {}}.
+
+Sending key events using Python
+For keypresses, set event_type to key and fill in the event structure with key and state, where key is the key from mapping and state is boolean that determines if the key is pressed or released:
+# python, install websocket-client
+import websocket
+import ssl, time
+uri = "wss://10.0.0.7/api/ws?stream=0"
+headers = {"X-KVMD-User": "admin", "X-KVMD-Passwd": "admin"}
+ws = websocket.WebSocket(sslopt={"cert_reqs": ssl.CERT_NONE})
+ws.connect(uri, header=headers)
+# Key codes: https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/code/code_values
+ws.send('{"event_type": "key", "event": {"key": "Enter", "state": true}}')
+time.sleep(0.05)
+ws.send('{"event_type": "key", "event": {"key": "Enter", "state": false}}')
+ws.close()
+

Switch
+
The PiKVM Switch API provides handles to control the PiKVM Switch: get information, set active ports, and control beacons.
+
The API heavily relies on specifying ports on the PiKVM Switch. There are two ways to do that: with continuous numbering or with float numbers. Both options are equally valid and supported.
+
+- With continuous numbering, ports enumeration starts at 0 and ends at 19, because you can create up to 20 ports by adding more PiKVM Switch devices to the first Switch's downlink.
+- If you use a float value, the integer part specifies the number of the unit in the downlink, while the fractional part specifies the number of the port on that unit.
