Why pay $0.0200?
Use this when deciding whether to buy, list, price, or benchmark an x402 endpoint.
The public page shows the market summary; the paid response gives route-specific decision fields.
You are paying for normalized comparison, price position, payer/call density, GMV estimate, confidence, and source trail.
