MAKE AI AGENTS PAY TO SCRAPE
Universal paywall system that enforces on-chain payments from bots and AI agents using the x402 payment protocol
const express = require("express");
const { paywall } = require("ai-paywall");
const app = express();
app.use("/hidden/dog", paywall({
price: "0.01",
receiver: "0x...",
domain: "www.demo1.com"
}));AI IS SCRAPING YOUR PREMIUM CONTENT FOR FREE
Bots, crawlers, and AI agents are accessing your research, APIs, and datasets without permission or payment. There's no standard enforcement mechanism.
WITHOUT SUI2SCRAPE
- No way to monetize content accessed by bots and crawlers
- Your research and APIs become free training data for AI models
- Zero control over who accesses your content or how often
- Content theft with no recourse or attribution
WITH SUI2SCRAPE
- Pay-before-access enforcement via x402
- On-chain payment verification with AccessPass
- Configurable usage limits and rate control
- End-to-end content encryption via Seal
HOW IT WORKS
A seamless end-to-end flow from content upload to AI agent payment
SYSTEM ARCHITECTURE
UPLOAD & ENCRYPT
Content creator uploads premium content through the gateway. Automatically encrypted with Seal and stored on Walrus decentralized storage.
INTEGRATE MIDDLEWARE
Install the npm package and protect your routes with the paywall() wrapper. Configure price, receiver address, and access rules in one line.
AI AGENT REQUESTS
When an AI agent or bot tries to access protected content, they receive a 402 Payment Required response with payment instructions.
ON-CHAIN PAYMENT
Agent pays via Sui smart contract. AccessPass is minted with usage limits, expiration, and metadata. Payment is verified on-chain.
VERIFY & DECRYPT
Gateway verifies the AccessPass, decrements usage counter, fetches encrypted content from Walrus, and Seal decrypts it.
ACCESS GRANTED
Decrypted content is returned to the AI agent. All transactions are logged on-chain for complete audit trail and analytics.
INTEGRATE IN MINUTES, NOT DAYS
Add AI payment enforcement to your existing application with minimal code changes
INSTALL THE PACKAGE
npm install ai-paywallADD THE MIDDLEWARE TO YOUR ROUTES
const express = require("express");
const { paywall } = require("ai-paywall");
const app = express();
app.use("/hidden/dog", paywall({
price: "0.01",
receiver: "0x...",
domain: "www.demo1.com"
}));
app.get("/hidden/dog", (req, res) => {
res.send(req.paywall?.encryptedBlob);
});THAT'S IT! YOUR CONTENT IS NOW PROTECTED
AI agents will now receive payment instructions when they try to access your protected routes. After successful payment, they'll receive an AccessPass and gain access to your premium content.

POWERED BY SUI, WALRUS & SEAL
Blockchain payments, decentralized storage, and encryption working together to protect your content
SUI BLOCKCHAIN
Stores domain-to-content mappings and mints AccessPass objects when AI agents pay. Each AccessPass tracks usage limits and expiry, enabling pay-per-access enforcement.
WALRUS STORAGE
Holds encrypted premium content off-chain. When AccessPass is verified, the gateway fetches the encrypted blob from Walrus using the CID stored on Sui.
SEAL ENCRYPTION
Encrypts content at upload and only releases decryption keys when a valid AccessPass exists. Without payment, content remains encrypted and unusable.
