What is x402 RPC Aggregator?

API gateway that intelligently routes RPC calls across multiple blockchain providers with automatic micropayment settlement, priced dynamically from USD to SOL or USDC

⚡

Multi-Provider Aggregation

Single API endpoint routes to 8+ RPC providers across Solana, Ethereum, and Base chains

🎯

Intelligent Routing

Automatically selects best provider based on cost, latency, priority, or custom preferences

💳

Micropayment Settlement

Pay-per-call with x402 protocol. No API keys, no subscriptions, just autonomous payments

How It Works

1

Call Unified API

POST /rpc with your RPC method

2

Intelligent Routing

System selects best provider (health, cost, latency)

3

Pay Automatically

Amount auto-converts from USD to SOL/USDC based on live pricing

4

Get RPC Result

Receive data with payment receipt

Simple Integration

Get started in 3 lines of code 

import { X402Agent } from '@x402/client';

const agent = new X402Agent('https://x402labs.cloud');
const result = await agent.callRPC('getSlot', [], 'solana');

// Agent handles payment automatically!
console.log('Current slot:', result.result);
// Payment converted from USD to SOL based on live oracle price
// Provider: Auto-selected
// Settlement: <1s

What Happened:

  • Agent called unified API endpoint
  • System selected Helius (highest priority, active)
  • Micropayment settled automatically (USD → SOL/USDC conversion)
  • RPC result returned with payment receipt
