View on GitHubWhat 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.
When to use it
- Finding a paid sentiment analysis API when you don't have one set up
- Checking the price of an x402 endpoint before committing to a call
- Calling a paid weather API with automatic USDC payment
- Browsing available paid services in the x402 bazaar by keyword
- Setting a max payment cap before making an expensive API request
