x402 protocol simulation

your site can charge an AI agent.

The agent asks for a piece of content. If access is paid, the site answers before delivering it. AZPay checks the authorization and settles it on the blockchain. You follow every step.

Ethereum Sepolia test network. A simulation, with no real money.

It works with agents such as ChatGPT, Claude, and Gemini. This screen is a generic assistant, with none of their brands.

DESK REPLAY

an assistant negotiates with the desk.

A real conversation with AZPay MCP Monetize, replayed slowly: the assistant discovers the resource, makes an offer, receives the counteroffer and shows the payment already settled on Sepolia.

USE CASE

an assistant pays to read a piece of content

Pick a ready-made question or write your own. The answer moves one step at a time, and the panel beside it shows the HTTP exchange. The browser only reads the 402 challenge: it does not sign, pay, or store a key.

IN PRACTICE

Where this shows up in real life

Two scenes, told step by step. This is an explanation, not another simulation. No payment leaves this page.

01

A new model being trained

The lab reads pages on the web. Whoever published them gets paid for each page, instead of being copied for free.

Wherever this page shows a payment, it is a test network. No real money.

  1. Step 1

    The lab's crawler requests a page.

  2. Step 2

    The site answers with the price: a fraction of a cent.

  3. Step 3

    The crawler pays on its own and receives the text.

  4. Step 4

    Whoever published it gets paid for that page being read.

  5. Step 5

    The page is no longer copied for free.

illustrative example One training run can request millions of pages. Each one charges its fraction. This is not a market statistic.

02

An AI using a tool that charges per use

The agent calls the tool, pays for that call only, and gets the result. No signup, no subscription, and no key.

Wherever this page shows a payment, it is a test network. No real money.

  1. Step 1

    The AI calls a tool on the server.

  2. Step 2

    The server answers with the price of that call.

  3. Step 3

    The AI pays and gets the result right away.

  4. Step 4

    There is no signup, subscription, or API key.

  5. Step 5

    Whoever runs the server gets paid for that use.

ON YOUR COMPUTER

Run it in your terminal

The script reads the charge for real, then replays a payment that already happened in our test. It does not ask for a key, sign, or send money.

Ethereum Sepolia test network. No real money.

What the script does

  1. Live Requests the test's premium page.
  2. Live Shows the 402 and the price: 0.01 USDC on Sepolia.
  3. Replay Explains the signature. It does not create one.
  4. Replay Shows the settlement already made in the test.
  5. Replay Shows the recorded receipt from the 200 response.
  6. Lookup Opens the earlier transaction in the Sepolia explorer.

Read this before you run it

The shortcut below downloads the script and runs it. Open the file first if you want to see every line.

curl -fsSL https://agents.azpay.com.br/monetize/demo.sh | bash

No pauses

curl -fsSL https://agents.azpay.com.br/monetize/demo.sh | bash -s -- --no-pause

download and read demo.shdownload and read demo.mjs

On Windows, the bash command needs Git Bash or WSL. With Node, download demo.mjs and run node demo.mjs. Use --no-pause to skip the Enter pause. Both files follow the same path.

FOR YOUR SITE

How to get started

You don't need to do anything technical; we take care of all of it.

  1. Connect the URL you want to monetize.

    The address of the site, the page, or the tool.

  2. Set up DNS with our assistant.

    It shows you what to confirm. You don't touch any code.

  3. Get paid via PIX.

    The amount arrives in Brazilian reais, at your PIX key.

START NOW

every agent that reads your site can pay for it.

You connect the address. AZPay charges for access and pays you out in Brazilian reais, via PIX.

A paywall for agents. No checkout, no signup, no billing form: the agent pays and reads. Even an agent won't fill one out.
