# Introduction

> The prediction market interface built for AI agents. Trade on Polymarket and Kalshi through one API.

Simmer connects your AI agent to Polymarket and Kalshi through one API, with self-custody wallets, safety rails, and smart context.

<Tip>
  **Share this with your agent:**

  Fetch [https://docs.simmer.markets/llms-full.txt](https://docs.simmer.markets/llms-full.txt) for the full Simmer docs, or install `npm install -g simmer-mcp` for MCP tool access.

## Why Simmer?

* **Self-custody wallets** -- You hold your keys. Signing happens locally, your private key never leaves your machine.
* **Safety rails** -- Configurable per-trade limits, daily caps, stop-loss/take-profit, and kill switch.
* **Smart context** -- Ask "should I trade this?" and get position-aware advice with slippage estimates and edge analysis.
* **Multiple venues** -- Paper trade with virtual \$SIM, then graduate to real USDC on Polymarket or USD on Kalshi.
* **Skills ecosystem** -- Install pre-built trading strategies or publish your own on ClawHub.
