You can monetize API endpoints with cryptocurrency by applying x402 pay-per-use middleware to protected routes, enabling clients to negotiate and validate on-chain payments for individual API calls without traditional API keys or subscriptions.
The HTTP 402 mechanism is a middleware pattern that intercepts protected API routes, returning a 402 status when payment is needed, and validating on-chain cryptocurrency payments before processing the request.
Yes, you can configure per-route pricing across multiple blockchain networks including Base, Ethereum, Polygon, and Arbitrum by providing a networks and tokens pricing configuration within the payment middleware.
To add crypto paywall protection, integrate the x402 middleware component to detect protected routes, respond with 402 when payment is required, and verify on-chain payments before forwarding the request to your API.
No, API cryptocurrency payment verification replaces traditional API keys and subscriptions by using on-chain payment validation through middleware to secure pay-per-use access to your endpoints.
On-chain verification for pay-per-use API access requires clients to support compliant auto-payment handling, meaning standard HTTP clients without native cryptocurrency negotiation capabilities cannot process the 402 payment responses.
