neurolink

English | 简体中文

neurolink is a Go Terminal UI for monitoring Apex Legends service health before or during play, with explicit on-demand Apex player stat lookup. It presents a Crypto-style surveillance dashboard focused on Apex service availability and quick pre-game inspection, not fake ICMP pings or background player tracking.

The app monitors service availability such as:

• Crossplay Auth
• Lobby / Matchmaking
• PC / Desktop Logins
• Player Accounts
• Apex Legends Status API health
• Recent community reports when the status payload includes them

The player view can query a player by name and platform (PC, PS4, or X1) using Apex Legends Status /bridge. Lookup only runs after a visible user action such as pressing Enter in the player view. PC lookup generally uses the Origin account name, even for Steam-linked accounts. neurolink does not continuously track players, query match history in the background, or hide telemetry.

Data Source

The primary data source is the Apex Legends Status public site/API ecosystem:

• Website: https://apexlegendsstatus.com/
• API docs/base: https://apexlegendsapi.com/
• API base: https://api.apexlegendsstatus.com/

The dashboard polls:

GET https://api.apexlegendsstatus.com/servers

The player view queries only on demand:

GET https://api.apexlegendsstatus.com/bridge?player=PLAYER_NAME&platform=PLATFORM

Both endpoints require an Apex Legends Status API key for live data. The app sends the key with the Authorization header and never hard-codes or logs sample tokens.

The /servers endpoint may return JSON with Content-Type: text/plain;charset=UTF-8, so the client sends Accept: */* and decodes the response body as JSON.

The normalized dashboard includes the core service cards above. Overall status is derived from playable game services; the Apex Legends Status API health card is shown separately so a status-site issue does not automatically mark Apex gameplay services as down.

The player lookup normalizes the /bridge response into identity, platform, UID, level, rank, selected legend, and tracker values. It intentionally avoids presenting continuous online/lobby tracking.

Install

From this checkout:

go install .

Or, when installing by module path:

go install github.com/Nesoriel/neurolink@latest

Run

Run with demo data:

neurolink

Run with live status polling as a one-off override:

neurolink --api-key "$YOUR_APEX_STATUS_API_KEY" --poll-interval 1m

The same flags work with go run . during development:

go run . --demo
go run . --lang zh-Hans

TUI Controls

• tab / shift+tab: switch views
• 1: dashboard
• 2: player lookup
• 3: config
• ?: help
• /: open player lookup and focus the player input
• enter: run player lookup from the player view
• p: cycle PC / PS4 / X1 when the player input is not focused
• r: request an immediate service status refresh
• q / ctrl+c: quit

Persistent Config

neurolink stores optional persistent settings in the cross-platform user config directory returned by Go's os.UserConfigDir():

<user-config-dir>/neurolink/config.json

Typical locations are ~/.config/neurolink/config.json on Linux, ~/Library/Application Support/neurolink/config.json on macOS, and %AppData%\neurolink\config.json on Windows.

Show the active config path:

neurolink config path

Persist settings:

neurolink config set api-key "$YOUR_APEX_STATUS_API_KEY"
neurolink config set language en
neurolink config set language zh-Hans
neurolink config set poll-interval 30s

You can also save multiple settings at once:

neurolink config set --api-key "$YOUR_APEX_STATUS_API_KEY" --lang zh-Hans --poll-interval 30s

Show saved settings. The API key is always masked:

neurolink config show

Unset saved settings:

neurolink config unset api-key
neurolink config unset language poll-interval
neurolink config unset all

Use a custom config path when needed:

neurolink --config ./local.config.json config show
neurolink --config ./local.config.json

Normal run precedence is:

defaults < config file < environment < flags

Environment Variables

• NEUROLINK_APEX_API_KEY: one-off API key override
• NEUROLINK_LANG: one-off language override, en or zh-Hans
• NEUROLINK_POLL_INTERVAL: one-off poll interval override, such as 30s or 1m
• NEUROLINK_CONFIG: config file path override

Flags still take final precedence:

NEUROLINK_APEX_API_KEY="$YOUR_APEX_STATUS_API_KEY" neurolink --poll-interval 1m
NEUROLINK_LANG=zh-Hans neurolink --lang en

Behavior Without an API Key

If no API key is available from the config file, environment, or --api-key, neurolink starts in demo mode. You can also force demo mode explicitly:

neurolink --demo

Demo mode uses deterministic sample data for UI preview and local development. The dashboard and player result cards label the source as DEMO and do not present sample data as live Apex service or player data.

Build and Test

Build:

go build ./...

Test:

go test ./...
go test -race ./...

Format:

gofmt -w .

Community Pulse

The top-right report panel is labeled Community Pulse. It shows recent community reports only when the /servers payload includes a report feed. If the feed is absent, the panel explains that the current /servers response does not include recent reports and keeps attribution to Apex Legends Status.

This panel is service-health context only. Player stats are available only through the explicit player lookup view.

Optional Ping Diagnostics

The older ICMP ping probe remains available only as an explicit diagnostics module. It is not the primary monitoring source and should not be presented as real Apex server monitoring unless concrete targets are configured.

On Linux, non-privileged ICMP diagnostics may require:

sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"

Current Limits and TODO

• The Apex Legends Status API payload shape may change; normalization handles common fields and core service aliases.
• Without an API key, only demo data is available.
• Recent community reports appear only when the /servers payload provides a report feed.
• Player lookup currently supports name + platform searches for PC, PS4, and X1; UID lookup is documented upstream but not exposed in this first TUI iteration.
• The player view summarizes stats from /bridge and avoids continuous online/lobby tracking.
• Ping diagnostics are not yet exposed as a dedicated TUI panel.
• Future work may add more service cards, richer status history, saved lookup defaults, and more granular desktop notifications.
