Machine-readable pricing

Agents can discover the same commercial surface directly from the provider catalogue, OpenAPI contract and x402 well-known document.

Prices shown are service fees only. Network or facilitator costs, if any, are outside zFinia's listed per-call price. Never send a seed phrase or private key to zFinia.
