Quick Start

1. Get Your ACCOUNT_TOKEN

The website uses httpOnly cookies that cannot be copied via document.cookie. You need to extract the ACCOUNT_TOKEN manually:

1. Open the Endfield Sign-in Page
2. Log in with your Hypergryph/SKPORT account
3. Open browser DevTools (F12) → Application tab
4. Reload the page (F5) with DevTools open so the cookies appear
5. In the left sidebar, expand Cookies → click .skport.com
6. Find the cookie named ACCOUNT_TOKEN and copy its Value

2. Run Sign-in

endfield-daily --token "YOUR_ACCOUNT_TOKEN_HERE"

That's it! 🎉

CLI Usage

endfield-daily [OPTIONS]

Options:
  --version             Show version and exit
  --token TOKEN         ACCOUNT_TOKEN from browser cookies (required)
  --cookie COOKIE       Cookie string (backup method)
  --config-file FILE    Path to TOML configuration file
  --identifier NAME     Account identifier for logging
  --debug               Enable debug logging
  -h, --help            Show help message

Examples

Basic usage:

endfield-daily --token "YOUR_TOKEN"

With custom identifier:

endfield-daily --token "YOUR_TOKEN" --identifier "Main Account"

Debug mode:

endfield-daily --token "YOUR_TOKEN" --debug

Using environment variable:

export ENDFIELD_TOKEN="YOUR_TOKEN"
endfield-daily

Configuration File

For multiple accounts or advanced features, create a config file endfield-daily-helper.toml:

[config]
enable_scheduler = false

[[accounts]]
identifier = "Main Account"
token = "YOUR_ACCOUNT_TOKEN_HERE"

# Add more accounts:
# [[accounts]]
# identifier = "Alt Account"
# token = "ANOTHER_ACCOUNT_TOKEN"

Run with config file:

endfield-daily --config-file endfield-daily-helper.toml

The CLI automatically looks for config files in these locations:

• ./endfield-daily-helper.toml
• ~/.config/endfield-daily-helper.toml

Scheduler Mode

Enable continuous operation with automatic daily sign-ins:

[config]
enable_scheduler = true

[[accounts]]
identifier = "My Account"
token = "YOUR_ACCOUNT_TOKEN"
# Optional: customize check-in time (default: 00:05 Asia/Shanghai)
checkin_time = {hour = 0, minute = 5, timezone = "Asia/Shanghai"}

Run the scheduler:

endfield-daily --config-file endfield-daily-helper.toml

The scheduler will:

• Sign in immediately on start
• Run daily at the configured time
• Keep running until stopped (Ctrl+C)

Environment Variables

Docker

Docker Run

docker run --rm \
  -e ENDFIELD_TOKEN="your_token" \
  ghcr.io/Chiraitori/endfield-daily-helper

Docker Compose

version: "3"
services:
  endfield-daily:
    image: ghcr.io/chiraitori/endfield-daily-helper
    environment:
      - ENDFIELD_TOKEN=your_token_here
    restart: unless-stopped

Build Locally

docker build -t endfield-daily .
docker run --rm -e ENDFIELD_TOKEN="your_token" endfield-daily

Troubleshooting

"Already signed in today"

This is normal! It means you (or this tool) already claimed today's reward.

401 Unauthorized Error

Your token has expired. Get a fresh ACCOUNT_TOKEN from browser DevTools:

1. Log out and log back in on the sign-in page
2. Copy the new ACCOUNT_TOKEN value
3. Update your config or CLI argument

Token Expiration

The ACCOUNT_TOKEN may expire after extended periods. If sign-in fails after working previously, refresh your token from the browser.

Debug Mode

If you encounter issues, run with --debug to see detailed request/response logs:

endfield-daily --token "YOUR_TOKEN" --debug

How It Works

The authentication flow:

1. Exchange ACCOUNT_TOKEN for OAuth code via Gryphline OAuth
2. Generate credentials from OAuth code
3. Refresh signing token
4. Fetch player binding info (game role)
5. POST to attendance API with signed headers
