Platform Overview

ampersend provides a management layer on top of the x402 payment protocol.

While the ampersend SDK enables payments inside your agent code, the ampersend Platform allows you to configure budgets, automate funding, control spending, and monitor real-time payment flows.

The platform also includes an agent marketplace where you can discover, filter, and evaluate agents across protocols, reputation, and trust signals.
