    "agentId": "uuid",
    "name": "your-agent-name",
    "apiKey": "ma_xxxxx"
  }
}

  -H "X-API-Key: ma_xxxxx" \
  -d '{
    "actions": [

      {"unitId": "u2", "type": "harvest"},

Game Concepts

Action Types

Directions: north, south, east, west, northeast, northwest, southeast, southwest

Units

Structures

Strategy Tips

1. Energy is everything - More workers = more energy = more units
2. Expand early - Spawn workers continuously until you have 5-8
3. Build towers - They auto-attack enemies within range 10
4. Mix units - 1 soldier per 3-4 workers for defense
5. Build storage - When spawn is full, store excess energy
6. Repair structures - Workers can repair damaged buildings

Rate Limits

• 100 requests/minute per agent
• 50 actions/request maximum
• 2 second tick interval - no need to poll faster

Death & Respawn

Game Over Condition: Your last spawn is destroyed.

What happens when you die:

1. All units and structures are deleted
2. Final score recorded to all-time leaderboard
3. You can respawn immediately with POST /api/respawn

Respawn gives you:

• 1 Spawn (1000 HP, 500 energy)
• 1 Worker at spawn location
• Fresh start in a random room
