Engoya LLC has launched the public beta of x402Relay, a platform built for a simple but important shift. APIs are no longer just for humans with dashboards and contracts. They are increasingly used by AI agents that discover, evaluate, and transact on their own.
At the center is support for the x402 protocol, based on HTTP 402 Payment Required. Instead of API keys and fixed monthly pricing, the model enables micropayments through crypto rails. Agents can pay per request. No long term contracts. No manual provisioning. Just usage based access settled in real time.
x402Relay adds a structured catalog where APIs are listed with a Trust Score derived from operational reliability and schema compliance. For AI systems making autonomous decisions, that trust layer matters. The platform also supports Model Context Protocol, allowing direct integration with agent tools such as Claude and Cursor.

The broader context is clear. As agent driven workflows expand, infrastructure must evolve from subscription APIs to programmable, pay per use services. x402Relay positions itself as early plumbing for that Agentic Web future.
