Get started monetizing your private IPFS files with x402 in just a few minutes. With x402, you monetize your private files by setting payment requirements. Payments go directly to your wallet. You control the price and receive the funds.
x402 is available on paid Pinata accounts. Upgrade your account to access x402 monetization features.

​
Prerequisites

  • Paid Pinata account
  • Pinata SDK installed
  • Ethereum wallet address to receive payments

​
Step 1: Upload a Private File

First, upload a file to Private IPFS: 
import { PinataSDK } from "pinata";

const pinata = new PinataSDK({
  pinataJwt: process.env.PINATA_JWT!,
  pinataGateway: "your-gateway.mypinata.cloud",
});

const file = new File(["file contents"], "your-file.pdf", {
  type: "application/pdf",
});
const upload = await pinata.upload.private.file(file);
const cid = upload.cid;
Save the returned cid for the next step.

​
Step 2: Create a Payment Instruction

Define your payment requirements: 
const instruction = await pinata.x402.createPaymentInstruction({
  name: "Premium Content Access",
  description: "One-time payment for file access",
  payment_requirements: [
    {
      asset: "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913", // USDC on Base
      pay_to: "YOUR_WALLET_ADDRESS", // YOU receive payments here
      network: "base",
      description: "Access fee",
      amount: "10000", // $0.01 in USDC
    },
  ],
});
const instructionId = instruction.data.id;
Understanding Payment Amounts: The amount uses USDC’s smallest unit. USDC has 6 decimals, so to convert USD to the token amount, multiply by 1,000,000:
USD AmountamountCalculation
$0.01"10000"$0.01 × 1,000,000
$0.10"100000"$0.10 × 1,000,000
$1.00"1000000"$1.00 × 1,000,000
$5.00"5000000"$5.00 × 1,000,000
$10.00"10000000"$10.00 × 1,000,000
Formula: USD Amount × 1,000,000 = token amount Networks:
  • Production: Use "base" (or "eip155:8453") with 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
  • Testing: Use "base-sepolia" (or "eip155:84532") with 0x036CbD53842c5426634e7929541eC2318f3dCF7e
Save the returned id for the next step.

​
Step 3: Attach CID to Payment Instruction

Link your private file to the payment instruction: 
await pinata.x402.addCid(instructionId, cid);

​
Step 4: Share Your Monetized Content

Your file is now monetized! Share this URL with requesters: 
https://your-gateway.mypinata.cloud/x402/cid/{cid}
Replace your-gateway.mypinata.cloud with your actual dedicated Pinata gateway domain (e.g., my-gateway.mypinata.cloud), and {cid} with your file’s CID.

​
Step 5: Test the Payment Flow

When a requester accesses your URL without payment, the gateway returns a 402 response with payment requirements: 
const response = await fetch(
  `https://your-gateway.mypinata.cloud/x402/cid/${cid}`
);
const paymentRequirements = await response.json();
console.log(paymentRequirements);
Response: 
{
  "x402Version": 1,
  "accepts": [{
    "scheme": "exact",
    "network": "base",
    "maxAmountRequired": "10000",
    "asset": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",
    "payTo": "YOUR_WALLET_ADDRESS",
    "resource": "https://your-gateway.mypinata.cloud/x402/cid/{cid}"
  }],
  "error": "Provide a valid X-Payment header to access this content"
}
After payment is made, requesters can access the file by including the payment proof in the X-Payment header.

​
Next Steps

  • Manage Multiple Files: Attach multiple CIDs to the same payment instruction
  • Update Pricing: Use updatePaymentInstruction
  • Monitor Access: Check your gateway analytics to track paid downloads
  • Requester Guide: Learn how requesters access paid content in the Accessing Paid Content guide

​
Common Issues

404 Not Found: Verify the CID is private and correctly attached to a payment instruction 403 Forbidden: Check that your API key has the required permissions 409 Conflict: If deleting a payment instruction fails, remove all CID attachments first Need help? Contact [email protected]
