Frequently Asked Questions
Everything you need to know about Sigwei and x402 payments
PayGates are payment-protected short proxy links that require USDC payment before accessing content or APIs. Create a PayGate to monetize any URL - users pay once and get credits for multiple accesses. Perfect for API providers, premium content, or AI agents needing automated access to paid services.
Connect your wallet, enter the amount and recipient (Ethereum address or ENS name), and click "Send" to sign the transfer. Transactions are irreversible, so verify details carefully. All transactions are subject to Coinbase's terms of service and Know Your Transaction (KYT) checks.
Go to PayGates, connect your wallet, and provide the target URL, price in USDC, and number of credits per payment. You'll get a short link that requires payment before redirecting users to your content. Great for monetizing APIs without code changes: ZERO code, ZERO infrastructure, ZERO maintenance.
x402 is an open protocol for Web3 payments over HTTP using the 402 “Payment Required“ status code. It enables seamless blockchain payments for web content and APIs without complex integrations. Learn more at https://x402.org .
