Creates a VPN monitor and queues its first check. Needs a role that can create monitors (Owner, Admin, or Manager), and room under the plan’s monitor limit.

The monitor tests from Any location. Choose specific locations in the dashboard. Monitors created through the API get no alert channels; pick them in the monitor’s settings in the dashboard.

The configuration fields depend on the protocol, so the body is one of the shapes below. protocol can be left out when url starts with a known scheme (vless://, vmess://, trojan://, ss://, hysteria2://, hy2://, tuic://).

Hosts in the IANA documentation ranges, such as example.com or 192.0.2.1, are refused with 422: use your own server’s address.

The 201 response always shows "tags": []. The tags are saved, in lowercase; read them back with Get monitor.

Tag names, saved in lowercase. A name the workspace doesn’t have yet creates the tag.

Array<string>
protocol

Optional when url starts with a known scheme.

string
Allowed values: vless vmess trojan shadowsocks hysteria2 tuic
url
required

The full share link, such as vless://… or ss://…. uri works as another name for it.

A usage limit was reached, or this IP address made too many requests with a wrong key.

Usage limits are per workspace and plan: per minute (Retry-After: 60), per day (Retry-After: 3600), and per month (no Retry-After). They use their own body shape. An IP address may send 10 wrong keys a minute; one more is allowed every 6 seconds. While that allowance is used up, every request from the address is refused, even one with a valid key.
