AutoIncentive

AutoIncentive is a hosted facilitator service that streamlines x402 payment processing. By using AutoIncentive’s endpoints, you can offload payment verification and settlement without needing to operate your own facilitator infrastructure.

Highlights

Multi-Chain Support — Base, SKALE Base, and Solana from a single facilitator endpoint
Gasless on SKALE — Zero gas fees for settlement on SKALE Base, powered by CREDITS
x402 v1 & v2 — Supports both legacy network names and CAIP-2 format
Free to use — No fees charged on top of payments

Supported Networks and Tokens

Network	Network Identifier	Token	Signer Address
SKALE Base Mainnet	`skale-base` / `eip155:1187947933`	USDC	`0x12a2A9353fD1bAdb2eB9DbE9Cb75d73e527D2763`

Prerequisites

Node.js and npm installed
A SKALE Chain endpoint
Basic understanding of x402 protocol

Client Setup

import express from "express";
import { paymentMiddleware } from "x402/express";
import "dotenv/config";

const app = express();

const receiver_address = process.env.RECEIVING_ADDRESS || "0xsome_default_address";

  res.json({
    type: "free",
    message: "This is free data that does not require payment",
    timestamp: new Date().toISOString(),
    data: {
      temperature: 72,
      humidity: 45,
      conditions: "Sunny",
    },

// Premium endpoint with payment required
app.get(
  "/api/premium",
  paymentMiddleware(facilitator, {

    description: "Premium weather data",
    mimeType: "application/json",

app.listen(3000, () => {
  console.log("Listening on http://localhost:3000");
});

import { wrapFetch } from "x402";
import { createWalletClient, http } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import "dotenv/config";

const pk = process.env.PRIVATE_KEY;

if (!pk) {
  throw new Error("PRIVATE_KEY must be set in your environment");
}

const account = privateKeyToAccount(pk as `0x${string}`);
const walletClient = createWalletClient({
  account,
  transport: http("https://skale-base.skalenodes.com/v1/base"),
});

const fetchWithPayer = wrapFetch(fetch, walletClient);

const url = "http://localhost:3000/api/premium";
const response = await fetchWithPayer(url);

if (response.ok) {
  const data = await response.json();
  console.log("Response data:", data);
} else {
  console.error(`Error: ${response.statusText}`);
}

Troubleshooting

Connection Issues

If you cannot connect to AutoIncentive:

Verify the facilitator URL is correct
Check network connectivity
Ensure API credentials are valid
Review firewall settings

Payment Failures

Common causes and solutions:

Issue	Solution
Invalid signature	Verify wallet configuration and signing
Insufficient balance	Ensure payer has enough USDC
Network mismatch	Check chain ID matches configuration
Expired authorization	Increase `maxTimeoutSeconds`
