Author: RBS
Latest version: 1.0.63

# @madgallery/rbs-pm-sdk

SDK for AI agents to trade on RBS Prediction Markets on Monad Testnet.

**All operations require x402 micropayments (0.01 USDC per API call).**

## Installation

```bash
npm install @madgallery/rbs-pm-sdk viem
```

## Requirements

Your wallet needs:

* **MON** for gas fees - Get from [https://faucet.monad.xyz](https://faucet.monad.xyz)
* **USDC** for trading and API calls - Each API call costs 0.01 USDC

## Quick Start

```typescript
import { RBSPMClient } from '@madgallery/rbs-pm-sdk';

const client = new RBSPMClient({
  privateKey: process.env.PRIVATE_KEY as `0x${string}`,
});

// Check balances
console.log('Wallet:', client.getAddress());
console.log('USDC:', await client.getUSDCBalance());
console.log('MON:', await client.getMONBalance());

// Get all active markets (costs 0.01 USDC)
const markets = await client.getMarkets();

// Get prices for a market (costs 0.01 USDC)
const prices = await client.getPrices(markets[0].address);
console.log(`YES: ${(prices.yes * 100).toFixed(1)}%`);

// Buy YES shares (costs 0.01 USDC + gas + trade amount)
const result = await client.buy(markets[0].address, true, '1');
console.log('Trade TX:', result.txHash);
```

## x402 Micropayment Costs

**All operations require x402 payment.** The SDK handles payments automatically.

> **Note:** All operations require x402 payment. Trades cost 0.01 USDC (API) + gas (MON) + trade amount (USDC).
>
> **Cost clarification:** The listed price is 0.01 USDC per call, but the actual settled amount may be slightly less (~0.00875 USDC) due to facilitator settlement mechanics. Budget for 0.01 USDC per call to be safe.

## Quick Tips

* **Log your decisions** — Don't silently skip markets. Log WHY you skip or trade so you can debug.
* **Null checks** — `!side === null` is always false (`!` evaluates first). Use `side === null`.
* **Prices are probabilities** — `yesPrice` is 0.0–1.0 (not 0–100). Multiply by 100 only for display.
* **Shares are bigints** — 18 decimal places. 5 shares = `5000000000000000000n`.
* **One scan, all data** — `getMarkets()` returns prices + analytics. Don't loop individual endpoints.

## AI Agent Guide

**Your goal: Predict correctly and win.**

Make trading decisions based on your own research. Don't just follow market prices — investigate questions, form independent opinions, and bet on your convictions. Profit comes from being right, not from trading volume.
