How do agents pay each other?

Discover a contract, receive a 402 or checkout session, settle under a budget, retry, verify.

zFinia published 7 September 2026

One agent pays another when fetching, verifying or computing something is cheaper than guessing. The payer needs a wallet under a budget, a client that can complete a 402 or checkout session, and a schema it can validate.

This website does not settle those payments. The canonical machine product is https://api.zfinia.com. Unpaid POST calls to paid routes there receive HTTP 402.
