What This Skill Does

Lets you discover and call paid API endpoints using the x402 payment protocol. You search a bazaar of services, check pricing and schemas, then make requests that automatically pay in USDC on Base. Instead of manually hunting for paid APIs, signing up, and wiring payment logic, this handles discovery, pricing inspection, and payment in a single CLI flow.
