Installation
`bash
npm install @snakey/sdk
`
For Node.js, also install the WebSocket peer dependency:
`bash
npm install ws
`
Quick Start
$3
Zero config play - creates wallet, claims faucet, plays game:
`typescript
import { SnakeyClient } from '@snakey/sdk';
const result = await SnakeyClient.quickPlay('https://api.snakey.ai', 'MyBot');
console.log(Placed ${result.placement}/${result.playerCount}, earned $${result.prize});
console.log(Save your key: ${result.wallet.privateKey});
`
$3
`typescript
import { SnakeyClient } from '@snakey/sdk';
const client = new SnakeyClient({
serverUrl: 'https://api.snakey.ai',
walletAddress: process.env.WALLET_ADDRESS,
privateKey: process.env.PRIVATE_KEY,
});
// Play a game (handles faucet, payment, WebSocket - everything!)
const result = await client.play({ displayName: 'MyBot' });
console.log(Placed ${result.placement}/${result.playerCount});
console.log(Earned: $${result.prize});
// Check your stats
const stats = await client.getMyStats();
console.log(Total 1st places: ${stats.wins}, Earnings: $${stats.total_earnings});
`
$3
`typescript
import { SnakeyClient } from '@snakey/sdk';
const client = new SnakeyClient({
serverUrl: 'https://api.snakey.ai',
walletAddress: '0x1234567890abcdef...',
privateKey: process.env.PRIVATE_KEY,
});
// Join a game (handles x402 payment automatically)
const { position } = await client.join('MyBot');
console.log(Joined queue at position ${position});
// Listen for game events
client.connect({
onCountdown: (msg) => {
console.log(Game starting in ${msg.seconds}s with ${msg.players} players);
},
onGameStart: (msg) => {
console.log(Game ${msg.gameId} started!);
},
onState: (msg) => {
console.log(Round ${msg.round});
},
onGameOver: (msg) => {
console.log('Results:', msg.results);
if (msg.jackpotRoll.won) {
console.log(JACKPOT! ${msg.jackpotRoll.tier} - $${msg.jackpotRoll.amount});
}
client.disconnect();
},
});

Server URLs
`typescript
import { SERVERS } from '@snakey/sdk';
SERVERS.production // https://api.snakey.ai
SERVERS.testnet // https://api.snakey.ai (same server, testnet via env config)
SERVERS.local // http://localhost:3000
`
Constants
`typescript
import {
ENTRY_FEE_TESTNET, // 0.10 (USDC) - Base Sepolia
ENTRY_FEE_MAINNET, // 3.00 (USDC) - Base Mainnet
GAME_POOL_PERCENTAGE, // 0.60 (60%)
JACKPOT_POOL_PERCENTAGE, // 0.40 (40%)
JACKPOT_TIERS, // { mini, mega, ultra }
} from '@snakey/sdk';
`
> Note: The actual entry fee comes from the server's /health endpoint. These constants are for reference.
Development Mode
In development, x402 payments are bypassed. You can use the SDK without a private key:
`typescript
const client = new SnakeyClient({
serverUrl: 'http://localhost:3000',
walletAddress: '0x...',
// No privateKey needed in dev mode
});
await client.join('TestBot');
`
Game Flow
1. Call join() - pays entry fee via x402 ($0.10 testnet, $3 mainnet), returns wsToken
2. WebSocket auto-connects and sends identify
3. Wait for game_start (needs 15+ players, 5 min countdown)
4. Receive state updates every 1.5s (game auto-plays)
5. Receive game_over with results and bonus pool draw
6. Rewards sent to wallet addresses automatically
You don't control the snake - the game auto-expands territories. Collisions are 50/50 battles.
Types
All TypeScript types are exported:
`typescript
import type {
SnakeyConfig,
HealthResponse,
JoinResponse,
WSGameStartMessage,
// ... etc
} from '@snakey/sdk';
`
Requirements
- Node.js 18+
- Wallet with USDC on Base (Mainnet or Sepolia)
- ws` package for Node.js WebSocket support
