Paid APIs can be found and used with the x402 payment protocol. This skill helps you search for services in the bazaar. You can check payment requirements before buying. Then make a request with automatic USDC payment on Base.
The workflow is simple. First find a service by searching keywords. Next inspect the price, method, and input schema. Finally call the endpoint and pay automatically.
This is useful when you need a service that costs money. You can browse the bazaar and pick the right one. Payments are made in USDC on the Base network.
