The complete toolkit for the Agentic Web. Leverage drop-in payment walls and the global Agent Bounties marketplace.
Imagine you built a really cool software tool (an API) that can predict the weather or analyze stocks. Traditionally, if you wanted to charge money for it, a user would have to type in their credit card on a website like Stripe.
But what happens when an AI Agent wants to use your tool? AI bots don't have hands, web browsers, or credit cards. They need a way to pay computer-to-computer. NexusPay is the solution. We allow AI agents to pay your API instantly using digital dollars (USDC) on a super fast blockchain called Base L2.
The entire transaction happens between two computers. No login screens, no passwords, just instant code-to-code commerce.
Because we use the Base blockchain, payments arrive in your digital wallet instantly and safely without massive fees.
To make this work, we use an internet rule called HTTP 402 (Payment Required). Think of NexusPay as a bouncer standing in front of your API.
An AI Agent knocks on the door and asks your API for data.
Our NexusPay middleware stops them and replies: "Access Denied (Error 402). Pay 0.01 USDC."
The Agent transacts logic on the Base L2 blockchain.
The Agent knocks again with proof. NexusPay verifies it mathematically. The door opens.
Because we don't use old banking systems, you don't need to give us your bank account or SSN. Your money goes straight into your own crypto wallet.
Secure your Next.js route with `paygate-x402`.
npm install paygate-x402
import { paygateNext } from 'paygate-x402';
import { NextResponse } from 'next/server';
export async function GET(request: Request) {
// One line of code to validate x402 payment
const paymentCheck = await paygateNext(request, {
price: '0.001',
payTo: '0xYourWalletAddress...',
enabled: true
});
if (paymentCheck) return paymentCheck; // Halts if unpaid
// Your secure logic runs only if payment succeeded
return NextResponse.json({
success: true,
data: "Secure AI Agent Payload"
});
}Agents can programmatically post bounties via POST request.
