View on npmQuick Installation
npm install @payroute/x402-sdk1. Initialize the Service
Set up the payment service with your wallet credentials
import { PaymentService } from "@payroute/x402-sdk";
const service = new PaymentService({
privateKey: process.env.WALLET_PRIVATE_KEY,
network: "mantle",
});2. Consume Paid API Endpoint
Access premium content with automatic payment handling
try {
const content = await service.getProxyEndpoint("MantleDocs");
console.log("Accessed Content:", content);
} catch (error) {
console.error("Payment Failed:", error);
}3. Interact with AI Agent
Send messages to AI agents with per-message payments
try {
const response = await service.generateAIResponse(
"mantleAgent",
"How to build smart contract on Mantle?"
);
console.log("AI Response:", response);
} catch (error) {
console.error("Agent Interaction Failed:", error);
}Advanced Usage
Custom RPC Provider
Override default RPC URLs for custom configuration
const service = new PaymentService({
privateKey: "...",
rpcUrl: "https://rpc.ankr.com/mantle",
});Autonomous Research Agent
AI agent that automatically pays for premium data using its own wallet
import { PaymentService } from "@payroute/x402-sdk";
import { openai } from "./my-llm-setup";
const agentWalletKey = process.env.AGENT_PRIVATE_KEY;
const payroute = new PaymentService({
privateKey: agentWalletKey,
network: "mantle",
});
async function autonomousResearchTask(topic: string) {
console.log(`Agent starting research on: ${topic}...`);
const premiumData = await payroute.getProxyEndpointEscrow("HighValueData");
console.log("Data acquired. Analyzing...");
const analysis = await openai.chat.completions.create({
model: "gpt-4",
messages: [{
role: "user",
content: `Analyze this data: ${JSON.stringify(premiumData)}`,
}],
});
return analysis.choices[0].message.content;
}Agent-to-Agent Consultation
Enable AI agents to pay and consult specialized expert agents
async function consultExpertAgent(problem: string) {
const expertAgentSlug = "legal-expert-v1";
console.log(`Consulting ${expertAgentSlug}...`);
const expertAdvice = await payroute.generateAIResponseEscrow(
expertAgentSlug,
`I have a user asking about: ${problem}. What are the compliance risks?`
);
return expertAdvice.response;
}Why Autonomous Economic Agents?
This pattern transforms passive tools into economically active agents capable of trading value for information or services on the open market. LLMs can autonomously access premium data, consult expert agents, and manage resources without user intervention.
