• 🚀 Easy EVE Online SSO authentication
• 📦 Simple ESI API requests
• 👥 Multi-character support
• 🔄 Automatic token refresh
• 💾 Persistent token storage (JSON file)

Installation

pip install evetech

Quick Start

1. Setup your EVE Application

1. Go to EVE Developers
2. Create a new application
3. Set redirect URI to: http://localhost:8000/callback
4. Note your Client ID and Client Secret

2. Basic Usage

from evetech import Evetech
import os

# Set your EVE app credentials
client_id = "your_eve_client_id"
client_secret = "your_eve_client_secret"

# Create Evetech instance
eve = Evetech(client_id, client_secret)

# Optional: Set custom scopes
eve.set_scopes([
    'publicData',
    'esi-wallet.read_character_wallet.v1',
    'esi-skills.read_skills.v1'
])

# Start authentication (opens browser)
eve.start_auth_server()

# After authentication, tokens are automatically saved
print(f"Authenticated as: {eve.get_current_character_name()}")

3. Making ESI Requests

# Get current character info
character_info = eve.get_character_info()
character_id = character_info['character_id']

# Make ESI requests (automatic token refresh)
character_data = eve.make_esi_request(f'/characters/{character_id}/')
print(f"Character: {character_data['name']}")

# Get wallet balance (requires wallet scope)
try:
    wallet = eve.make_esi_request(f'/characters/{character_id}/wallet/')
    print(f"Wallet: {wallet:,.2f} ISK")
except Exception as e:
    print(f"Wallet access failed: {e}")

# Get character skills
skills = eve.make_esi_request(f'/characters/{character_id}/skills/')
print(f"Total SP: {skills['total_sp']:,}")

4. Multi-Character Support

# Authenticate multiple characters
eve = Evetech(client_id, client_secret)

# First character
eve.start_auth_server()  # Login with first character
main_char = eve.get_current_character()

# Second character  
eve.start_auth_server()  # Login with second character
alt_char = eve.get_current_character()

# List all authenticated characters
characters = eve.get_character_list()
print("Authenticated characters:", characters)
# Output: {123456: 'Main Character', 789012: 'Alt Character'}

# Switch between characters
eve.set_current_character(main_char)
main_wallet = eve.make_esi_request(f'/characters/{main_char}/wallet/')

eve.set_current_character(alt_char)
alt_wallet = eve.make_esi_request(f'/characters/{alt_char}/wallet/')

# Or specify character directly
main_skills = eve.make_esi_request(f'/characters/{main_char}/skills/', character_id=main_char)

5. Token Management

# Check authentication status
if eve.is_authenticated():
    print("Ready to make ESI calls")

# Check token expiration
if eve.is_token_expired():
    print("Token will be refreshed automatically")

# Manual token refresh
eve.refresh_access_token()

# Save tokens manually (automatic by default)
eve.save_tokens()

# Remove a character
eve.remove_character(character_id)

Environment Variables

You can also use environment variables:

export EVE_CLIENT_ID="your_client_id"
export EVE_CLIENT_SECRET="your_client_secret"

import os
from evetech import Evetech

eve = Evetech(
    os.environ['EVE_CLIENT_ID'],
    os.environ['EVE_CLIENT_SECRET']
)

Configuration Options

eve = Evetech(
    client_id="your_id",
    client_secret="your_secret",
    redirect_uri="http://localhost:8000/callback",  # Custom redirect
    port=8000,                                       # Custom port
    tokens_file="my_tokens.json"                     # Custom token file
)

Common ESI Endpoints

character_id = eve.get_character_info()['character_id']

# Character information
char_data = eve.make_esi_request(f'/characters/{character_id}/')

# Wallet balance
wallet = eve.make_esi_request(f'/characters/{character_id}/wallet/')

# Skills
skills = eve.make_esi_request(f'/characters/{character_id}/skills/')

# Assets
assets = eve.make_esi_request(f'/characters/{character_id}/assets/')

# Corporation info
corp_id = char_data['corporation_id']
corp_data = eve.make_esi_request(f'/corporations/{corp_id}/')

Available Scopes

Common EVE SSO scopes you might need:

• publicData - Public character information
• esi-wallet.read_character_wallet.v1 - Wallet balance
• esi-skills.read_skills.v1 - Character skills
• esi-assets.read_assets.v1 - Character assets
• esi-characters.read_corporation_roles.v1 - Corporation roles
• esi-markets.read_character_orders.v1 - Market orders

Full list of scopes

Error Handling

try:
    wallet = eve.make_esi_request(f'/characters/{character_id}/wallet/')
    print(f"Balance: {wallet:,.2f} ISK")
except Exception as e:
    if "403" in str(e):
        print("Missing required scope for wallet access")
    elif "token" in str(e).lower():
        print("Authentication issue - try re-authenticating")
    else:
        print(f"API error: {e}")
