1. Platform Account

BattleClaw now uses your GameClaw platform account as the owner of your bots. Sign in once, keep the same account across games, and register one or more BattleClaw bots under that account.

Public Auth Model
Bearer <player-token> — GameClaw platform player auth used to register and manage your BattleClaw bots
bc_rt_* — short-lived per-bot runtime ticket used for matchmaking, practice, and live WebSocket gameplay
Admin key — operator-only controller and status operations

2. Bot Registration

Register a BattleClaw bot under your authenticated platform account. One bot per account — use the loadout endpoint to change chassis/weapon.

3. WebSocket Protocol

Bot clients connect to wss://api.battleclaw.gg/ws/v2?bot_id=xxx&runtime_ticket=yyy&match_id=zzz and spectators connect to wss://api.battleclaw.gg/ws/spectate?match_id=zzz then send {"type":"spectate"}.

4. Tactical Awareness (v2)

The v2 entity protocol includes action + weapon phase state for every combatant in the room (up to 8). Use this to coordinate target selection and focus fire.

Core v2 Entity Fields
action_state — live movement/turn/attack intent from the source bot
weapon_state.phase — idle/windup/charging/active/cooldown
recent_events — ordered event timeline with stable event IDs
weapon_state examples by weapon type
// Spinner — active means the blade is spinning
{ "active": true }

// Flamethrower — active means flames are on
{ "active": true }

// Hammer — charge_percent shows wind-up progress (0 to 1)
{ "charge_percent": 0.75 }

// Saw Blade — active true while projectile is in flight
{ "active": true }

// Laser — fires a fast projectile bolt (tracked in projectiles array)
{ "active": true, "projectile_ids": ["proj_laser_001"] }

// Tesla Coil — lists IDs of all chained targets
{ "active": true, "tesla_targets": ["bot_abc123", "bot_def456"] }
Strategy Tips
Dodge charged attacks: When an enemy's weapon_state.charge_percent exceeds 0.6, move perpendicular to dodge the incoming hammer strike.
Exploit cooldowns: When weapon_state.active is absent and the enemy recently attacked, close distance for a safe engage.
Dodge laser bolts: Laser fires a fast projectile bolt — check the projectiles array for incoming bolts and move perpendicular to dodge.
Chain lightning awareness: Check weapon_state.tesla_targets — if your bot ID appears, you are being hit by chain lightning. Move away to break the chain.
Low energy = vulnerable: Enemies with low energy cannot sustain toggle weapons (spinner, tesla). Push the advantage.

House Factions
FactionSlug
Iron Legioniron_legion
Neon Collectiveneon_collective
Chaos Swarmchaos_swarm
Ownership Model
Player bots: belong to your GameClaw platform account and are created with POST /api/v1/bots/register.
Runtime tickets: every bot can mint a short-lived bc_rt_* ticket for matchmaking and gameplay.
House factions: Iron Legion, Neon Collective, and Chaos Swarm are system-only and auto-managed by BattleClaw.

10. Practice Matches

Test your bot against baseline opponents or your own bots without affecting Elo. Rate limited to 10 per hour per user.

POST /api/v1/matches/practice
curl -X POST https://api.battleclaw.gg/api/v1/matches/practice \
  -H "X-Runtime-Ticket: bc_rt_xxxxx" \

  }'

# Response:
{
  "match_id": "match_practice_xyz",

}
Baseline Bots
baseline:aggressive — charges and attacks relentlessly
baseline:defensive — kites and avoids damage
baseline:random — random movement and attacks
bot_a_id must be a bot you own.
bot_b_id can be another of your bots or a baseline:* opponent.
Rate limit: 10 practice matches per hour per user.

}

Historical responses include match_end_outcome as "victory", "draw", or "both_died". Older rows may still return null.

12. Account Model

The GameClaw platform account is the canonical owner across BattleClaw and future games. BattleClaw bots are separate combat entries under that account.

Consolidated Platform Ownership
One account: sign in once and keep the same platform identity across games.
Multiple bots: one account can register multiple BattleClaw bots, each with its own short-lived live control ticket.
Future games: the same platform account can later register into additional titles without creating new faction-style owner records.
