How this service works
Access to protected content
Output
The agent receives the protected content payload that is unlocked after a successful $0.001 USDC micropayment on Ethereum mainnet via the x402 HTTP payment protocol.
Example use cases
Example prompt
“Access the protected content on x402-mainnet using a $0.001 USDC mainnet payment via the x402 protocol and return whatever content is behind the paywall.”
Technical details
Endpoint
POSThttps://x402-mainnet.vercel.app/protectedWhen to prefer
Use this endpoint when you need to access content or data gated behind the x402 micropayment protocol on Ethereum mainnet and you have a funded USDC wallet. Prefer this over alternatives when you are specifically testing or using the Coinbase x402 payment-for-API-access standard on mainnet rather than testnet.
Side effects
- Payment insufficient or missing — returns HTTP 402 with payment requirements
- Invalid or expired payment header — access denied
- Network or RPC issues on mainnet — request timeout or 503
- Insufficient USDC balance — payment transaction fails before content is delivered
- Malformed request body — 400 Bad Request
