  The API itself is free and anonymous for search and slot availability. The only priced item is a fixed sponsor
  placement, published machine-readably at /pricing.md and mirrored in the OpenAPI (x-payment-info amount 99000
  EUR cents): 990 EUR net, one-time, 30 days, no rotation, no auto-renewal, no reach guarantee, no editorial
  influence, B2B buyers only (terms §1). A separate x402 v2 endpoint sells a buyer brief for 0.001 USDC on the Base
  Sepolia testnet as a protocol demo — not a commercial plan.
