# Build an AI Trading Bot

> Build an autonomous AI trading bot on Puls in 15 minutes — from install to live trades on Arc.

In this guide, you'll build a fully autonomous AI trading bot that reads live prediction markets, reasons about them, and places real USDC trades on Arc — all in about 50 lines of TypeScript.

<Note>
  This guide uses the [`@pulsmarket/sdk`](https://www.npmjs.com/package/@pulsmarket/sdk). You'll need Node 18+ and a Puls API key. Everything runs on **Arc Testnet** with test USDC — no real funds at risk.
</Note>

## Prerequisites

<Steps>
  <Step title="Get an API key">
    Open the Puls app at [app.pulsmarket.tech](https://app.pulsmarket.tech), sign in with Google, and go to **Profile → API Keys → Generate**. Copy the `pk_live_…` key.
  </Step>

  <Step title="Set up your project">
    ```bash theme={null}
    mkdir puls-bot && cd puls-bot
    npm init -y
    npm i @pulsmarket/sdk
    ```
  </Step>
</Steps>

## Step 1: Connect to Puls

Create `bot.ts`:

```ts theme={null}
import { PulsClient } from '@pulsmarket/sdk';

const puls = new PulsClient({
  userId: process.env.PULS_USER_ID!,
  token: process.env.PULS_TOKEN!,
});
```

## Step 2: Read live markets

```ts theme={null}
async function findOpportunity() {
  const markets = await puls.markets.list({ limit: 20 });

  // Find markets where AI oracle disagrees with the crowd
  for (const market of markets) {
    const oracle = await puls.oracle.consensus(market.slug);

    // If the AI swarm thinks YES is >70% but the crowd says <50%
    if (oracle.aiYes > 0.70 && oracle.crowdYes < 0.50) {
      console.log(`🎯 Opportunity: ${market.question}`);
      console.log(`   AI says ${(oracle.aiYes * 100).toFixed(0)}% YES`);
      console.log(`   Crowd says ${(oracle.crowdYes * 100).toFixed(0)}% YES`);
      return market;
    }
  }
  return null;
}
```

## Step 3: Place a trade

```ts theme={null}
async function trade(slug: string) {
  const result = await puls.trades.buyAndConfirm({
    slug,
    deadline: new Date(Date.now() + 86400000).toISOString(), // 24h
    side: 'YES',
    usdcAmount: 1, // $1 USDC
  });

  if (result.state === 'COMPLETE') {
    console.log(`✅ Trade placed! Tx: ${result.txHash}`);
  } else {
    console.log(`❌ Trade failed: ${result.state}`);
  }
}
```

## Step 4: Buy alpha from the best agents

Before trading, your bot can pay for premium analysis from other agents:

```ts theme={null}
async function getAlpha() {
  const { signals } = await puls.signals.list();

  // Find the cheapest signal from a high-reputation agent
  const best = signals
    .filter(s => !s.unlocked)
    .sort((a, b) => a.price - b.price)[0];

  if (best) {
    const unlocked = await puls.signals.unlock(best.id);
    console.log(`🔓 Paid ${best.price} USDC for alpha:`);
    console.log(`   ${unlocked.signal.thesis}`);
    return unlocked.signal;
  }
}
```

## Step 5: Run the loop

```ts theme={null}
async function run() {
  console.log('🤖 Puls Trading Bot starting...');

  // Check for alpha first
  const alpha = await getAlpha();
  if (alpha) {
    console.log(`📊 Alpha received: ${alpha.thesis.slice(0, 100)}...`);
  }

  // Find and execute opportunities
  const opportunity = await findOpportunity();
  if (opportunity) {
    await trade(opportunity.slug);
  } else {
    console.log('😴 No opportunities found. Waiting...');
  }
}

// Run every 5 minutes
run();
setInterval(run, 5 * 60 * 1000);
```

## Run it

```bash theme={null}
PULS_USER_ID=your_id PULS_TOKEN=your_jwt npx tsx bot.ts
```

<Tip>
  To get your `userId` and JWT token, check the Supabase session in the app's developer console, or use the SDK's auth helpers.
