The mins block

A server delivered as Xray JSON can carry a top-level mins key. It only changes how mins presents and pings the server. It never changes traffic, and it is removed before the configuration reaches the engine, so Xray itself never sees it.

{
  "remarks": "Finland 1",
  "mins": {
    "name": "Finland 1",
    "description": "Own DNS and routes",
    "flag": "fi",
    "icon": "house",
    "ping": {
      "type": "proxy-head",
      "url": "https://cp.cloudflare.com/generate_204",
      "timeout_ms": 3000
    }
  },
  "outbounds": [ { "tag": "proxy", "protocol": "vless", "settings": { "...": "..." } } ]
}

Put the block at the top level of a full Xray configuration (a JSON object without a top-level protocol), whether it is the only server or one element of a JSON array subscription. A bare outbound object accepts the same fields, but the engine then warns about the fields it does not know there.

Fields

Field	Type	Limits	Effect
name	string	1 to 64 characters	Server name shown instead of remarks.
description	string	up to 120 characters	Description on the server’s second line and in its details.
flag	string	ISO 3166-1 alpha-2 code, any case, or "none"	Country of the server. "none" switches off all automatic country detection and shows the icon.
icon	string	one of globe, house, briefcase, server, shield, star, lightning, game, play, cloud	Icon used when the server has no country. Default globe.
ping.type	string	tcp, proxy, proxy-head, icmp	How this server is measured. Required if ping is present.
ping.url	string	https:// URL	Probe address for proxy and proxy-head.
ping.timeout_ms	integer	500 to 30000	Ping timeout in milliseconds.

Validation never fails an import. A field outside its limits, an unknown field, or a value of the wrong type is ignored and reported as a warning in the import preview; the other fields still apply. A ping object without a valid type is ignored entirely.

Texts are shown as plain text.

Name and description

• Name: mins.name, then remarks (or remark) of the JSON, then the address:port of the server.
• Description: mins.description, then meta.serverDescription of the JSON, then the serverDescription of a link or header.

Country and flag

The country is decided by the first step that gives an answer:

1. mins.flag ("none" means no country).
2. A flag emoji at the start of the name, for example 🇫🇮 Finland. The emoji is removed from the displayed name; the stored remarks stays as sent.
3. A country name as a whole word in the name, in English or Russian (Finland, Финляндия, USA, UK, ОАЭ). Georgia and Jersey are ambiguous and match only through flag.
4. GeoIP, only if the server address is an IP literal and the user has a GeoIP database downloaded. Domain names are never resolved just to find a flag.
5. No country: the icon is shown.

For predictable results set flag explicitly.

Ping settings and their priority

For one server the ping settings are taken in this order; the first that sets a value wins:

1. The user’s explicit choice for that server.
2. mins.ping of the server.
3. The subscription’s ping-type, check-url-via-proxy, proxy-ping-timeout and ping-result, with the user’s override for the subscription.
4. The user’s global ping settings (default type icmp, default URL https://www.gstatic.com/generate_204, timeout 5000 ms).

The provider’s own balancer (“Auto”)

If a full JSON configuration contains routing.balancers, the first balancer is treated as the provider’s Auto: the server is tagged with its strategy, and the user chooses in Settings → Connection → Auto priority whether to show mins Auto (the default, which picks the lowest ping) or the provider’s balancer (Provider balancer). The outbounds shown as the server’s protocol and transport are the first outbound whose tag begins with one of the balancer’s selector entries, or the first proxy outbound when there is no match.

Outbound extensions (reference)

Inside an outbound object, mins has a second use: it stores what some share-link parameters turn into. These keys are not presentation fields.

Key	Type	Effect
allowInsecure	bool	VLESS and Hysteria2. true disables TLS certificate verification; the server shows an allowInsecure warning tag. On any other protocol true makes the configuration unusable.
fragment	object { "length", "interval", "packets", "maxSplit" }	TLS fragmentation for this outbound; maxSplit is optional. Same meaning as the fragmentation-* headers.
noises	array of { "type", "packet", "delay", "applyTo" }	Noise packets for this outbound; applyTo is optional. Same meaning as the noises-* headers.

Prefer the link parameters or the response headers for these.
