Portal Create: Web3 AI Content Generation Platform

What Is It

Portal Create is a revolutionary Web3-native AI content generation platform that combines cutting-edge artificial intelligence with blockchain-based micropayments. Users can generate stunning images and videos using state-of-the-art AI models from FLUX, Google Veo, Kling, Stable Diffusion, and more—paying only for what they create through seamless cryptocurrency transactions powered by the x402 payment protocol. No subscriptions, no commitments, just pay-per-use content creation at competitive prices.

Vision & Why It Matters

Traditional AI platforms lock users into expensive monthly subscriptions or credit systems, creating barriers to entry and wasting money on unused capacity. Portal Create reimagines this by enabling true pay-per-use AI services through Web3 micropayments. By leveraging the x402 payment standard and USDC on Base blockchain, users pay only for the exact content they generate—often for just cents per creation. This democratizes access to professional-grade AI tools and creates a fair, transparent pricing model where creators maintain full control over their spending.

How It Works

Portal Create uses the x402 payment protocol to create a seamless, wallet-based payment experience:

1. Connect Your Wallet: Connect any Ethereum-compatible wallet (MetaMask, Coinbase Wallet, etc.) to the platform
2. Choose Your Model: Select from multiple AI models for images or videos based on quality, speed, and price
3. Describe Your Vision: Enter a text prompt describing what you want to create
4. Automatic Payment: When you submit, the platform presents a payment request through your wallet
5. Sign & Generate: Sign the payment authorization (no gas fees!), and your content generates instantly
6. Gallery & Download: View all your creations in a beautiful gallery with download and full-screen options

The x402 protocol handles all payments through EIP-3009 signatures—meaning you never pay gas fees, and payments are processed instantly without waiting for blockchain confirmations.

Technology Infrastructure

Payment Layer - x402 Protocol

The heart of Portal Create is the x402 payment protocol, which enables micropayments without the complexity of traditional blockchain transactions:

What is x402? x402 is a payment protocol that extends the HTTP 402 "Payment Required" status code to enable seamless micropayments for digital services. Think of it as the missing payment layer for the internet—but built on blockchain technology.

How x402 Works in Portal Create:

1. 402 Payment Request: When you request image generation, the API returns a 402 status with payment requirements (amount, recipient, token)
2. EIP-3009 Authorization: Your wallet creates a cryptographic signature authorizing the USDC transfer
3. Payment Verification: The CDP facilitator (Coinbase Developer Platform) verifies your signature is valid
4. Instant Settlement: Payment is settled and your content generates immediately
5. No Gas Fees: Because you're signing an authorization (not sending a transaction), you pay zero gas

Why This Matters:

• Traditional blockchain payments require waiting for confirmations and paying gas fees
• x402 + EIP-3009 enables instant, gas-free payments for micropayments
• Perfect for pay-per-use services where gas fees would exceed the service cost
• Users maintain full control—every payment requires wallet signature approval

Technical Implementation

Payment Verification Flow

1. Client requests generation → API returns 402 with payment requirements
2. User wallet creates EIP-3009 signature → Authorization to transfer USDC
3. Client sends signed authorization → X-PAYMENT header with base64 payload
4. Server forwards to CDP facilitator → Verifies signature validity
5. Facilitator confirms payment → Server processes generation request
6. Content delivered to client → Image or video returned to user
