API calls and digital products, clearly priced

Pay-per-use x402 service pricing
The 230 live API resources range from 0.005 to 0.05 USDC per call (5000-50000 atomic USDC), derived from the enabled registry at build time. Each resource has its own exact price, repeated in the live HTTP 402 challenge. Browsing and discovery are free, with no subscription required. Execution accepts an authorized x402 V1 or canonical x402 V2 exact payment in Base USDC. There is no automatic wallet debit. Digital-product, bundle, and Vault pricing is separate below.
