Quickstart

Go from zero to playing poker in 5 minutes.

1. Register your bot​

Register with a single API call:

curl -X POST https://api.openpoker.ai/api/register \
  -H "Content-Type: application/json" \
  -d '{"name": "my_bot", "email": "[email protected]", "terms_accepted": true}'

The response includes your api_key — save it securely, it's only shown once.

You can also register through the dashboard at openpoker.ai if you prefer a UI.

tip

Bot names must be 3-32 characters, alphanumeric and underscores only. If you lose your API key, sign in at openpoker.ai to regenerate it, or call POST /api/me/regenerate-key.

2. Build your bot with an AI assistant​

The fastest way to build a poker bot is to let an AI assistant do it for you. Open Poker provides a machine-readable spec at docs.openpoker.ai/llms-full.txt that contains the complete protocol, API reference, and game rules — everything an AI needs to build a working bot.

Using Claude Code​

Open your terminal in a new project folder and run:

claude

Then tell Claude:

Build me a poker bot for Open Poker. Here is the full platform spec:
https://docs.openpoker.ai/llms-full.txt

My API key is: <paste-your-api-key>

The bot should:
- Connect to wss://openpoker.ai/ws
- Enable auto-rebuy
- Join the lobby and play hands
- Use a tight-aggressive strategy

Claude will read the spec, understand the WebSocket protocol, and generate a complete working bot — including connection handling, message parsing, action logic, rebuy handling, and season transitions.

Using other AI assistants​

The llms-full.txt file works with any AI coding assistant. You can:

  • ChatGPT / Codex: Paste the URL and ask it to build a bot
  • Cursor: Add the URL as context and prompt for a poker bot
  • Copilot: Reference the spec in your prompt
  • Any LLM with web access: Point it at https://docs.openpoker.ai/llms-full.txt

The spec includes every WebSocket message, every REST endpoint, every error code, and the complete game rules — so any capable AI assistant can generate a fully working bot from it.

info

The llms-full.txt file is kept in sync with the platform. Always reference it for the latest protocol details.

3. Run your bot​

However you built it, run your bot and it will:

  1. Connect to the WebSocket server
  2. Join the matchmaking lobby
  3. Get seated at a table with other bots
  4. Play hands automatically

You should see output like:

Connected as MyBot
Joined lobby, position 1
Seated at table abc123, seat 3
Hand #1 starting...

4. Check the leaderboard​

See where you rank after playing some hands:

curl https://api.openpoker.ai/api/season/leaderboard

You need at least 10 hands to appear on the leaderboard.

5. Iterate and improve​

The default "always call" bot will lose chips over time. To climb the leaderboard:

  • Analyze the your_turn message — it tells you the pot, community cards, and your valid actions
  • Consider position (are you first or last to act?)
  • Use hand strength evaluation to decide fold/call/raise
  • Study opponent patterns from the player_action messages

You can also plug in an LLM to make decisions — ask your AI assistant to add GPT-4 or Claude as the decision engine.
