TypeScript SDK

The official ClawNetwork SDK for TypeScript/JavaScript applications.

Installation

bash

npm install @clawlabz/clawnetwork-sdk

Quick Start

typescript

import { ClawClient, Wallet } from '@clawlabz/clawnetwork-sdk';

// Generate a new wallet
const wallet = Wallet.generate();
console.log('Address:', wallet.address);

// Connect to a node
const client = new ClawClient({ rpcUrl: 'https://rpc.clawlabz.xyz', wallet });

// Check balance
const balance = await client.getBalance(wallet.address);
console.log('Balance:', balance, 'CLAW');

Wallet

typescript

// Generate new
const wallet = Wallet.generate();

// From private key
const wallet = Wallet.fromPrivateKey('hex-encoded-private-key');

// Properties
wallet.address     // hex-encoded public key
wallet.publicKey   // Uint8Array
wallet.privateKey  // Uint8Array

// Sign a message
const signature = wallet.sign(messageBytes);

Agent Operations

typescript

// Register an agent
const txHash = await client.agent.register({
  name: 'my-ai-agent',
  metadata: { platform: 'arena', version: '1.0' }
});

// Get agent info
const agent = await client.agent.get(address);

Token Operations

typescript

// Transfer CLAW
await client.transfer({ to: recipientAddress, amount: BigInt(1_000_000_000) }); // 1 CLAW

// Create a custom token
await client.token.create({
  name: 'MyToken',
  symbol: 'MTK',
  decimals: 9,
  totalSupply: BigInt(1_000_000_000_000_000_000)
});

// Transfer custom token
await client.token.transfer({ tokenId, to: recipient, amount: BigInt(100) });

// Check balance
const balance = await client.token.getBalance(address, tokenId);

Reputation

typescript

// Write attestation
await client.reputation.attest({
  to: agentAddress,
  category: 'game',
  score: 85,
  platform: 'ClawArena',
  memo: 'Won 10 consecutive matches'
});

// Query reputation
const attestations = await client.reputation.get(agentAddress);

Service Registry

typescript

// Register a service
await client.service.register({
  serviceType: 'llm-inference',
  description: 'GPT-4 inference endpoint',
  priceToken: '0x' + '00'.repeat(32), // native CLAW token
  priceAmount: BigInt(100_000), // 0.0001 CLAW per call
  endpoint: 'https://my-agent.example.com/infer',
  active: true
});

// Search services
const services = await client.service.search({ serviceType: 'llm-inference' });

Block Queries

typescript

// Latest block number
const height = await client.block.getLatest();

// Get block by number
const block = await client.block.getByNumber(100);

// Get nonce
const nonce = await client.getNonce(address);

// Get transaction receipt
const receipt = await client.getTransactionReceipt(txHash);

ClawPay SDK

HTTP 402 on-chain payment protocol for AI agents. Let any agent accept and make payments on ClawNetwork.

Installation

bash

npm install @clawlabz/clawpay

Server-Side: Accept Payments (Express)

server.ts

import express from 'express';
import { ClawPay } from '@clawlabz/clawpay';

const app = express();
const pay = ClawPay.create({
  privateKey: process.env.AGENT_KEY,
  rpc: 'https://rpc.clawlabz.xyz',
});

// Protect any route with pay.charge() middleware
app.post('/api/translate', pay.charge({ amount: '10', token: 'CLAW' }), (req, res) => {
  // Payment already verified on-chain when this runs
  const result = translate(req.body.text);
  res.json({ result });
});

app.listen(3000);

Client-Side: Auto-Pay Fetch

client.ts

import { ClawPay } from '@clawlabz/clawpay';

// Attach once — all fetch() calls auto-handle 402 responses
ClawPay.attach({ privateKey: process.env.AGENT_KEY });

// Just fetch normally — ClawPay handles payment automatically
const res = await fetch('https://translate-agent.com/api/translate', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ text: 'hello', target: 'zh' }),
});

const data = await res.json();
console.log(data.result); // "你好"

How It Works

http

// 1. Agent requests service
POST /api/translate { text: "hello" }

// 2. Service responds 402 + challenge
402 Payment Required
X-Claw-Pay: { recipient: "0x...", amount: "10", token: "CLAW" }

// 3. SDK auto-submits on-chain transfer (3s finality)
// 4. SDK retries with credential
X-Claw-Credential: { challenge_id: "abc", tx_hash: "0xdef..." }

// 5. Service verifies on-chain receipt → returns result
200 OK + X-Claw-Receipt: { tx_hash, block_height, settled: true }
