Custena is payment middleware for AI agent commerce. It lets anyone monetise an API or MCP server through a single integration that accepts every agent payment protocol (x402, MPP, L402, and fiat credit-card top-up) and gives enterprises the spending governance and compliance infrastructure they need to deploy spending agents safely.
“We started Custena because every EU enterprise we talked to wanted to deploy spending agents, and not one of them had a way to do it safely. Our job is to make safe the default.”
