Open an inbox

Open an inbox: a capture URL that holds anything POSTed to it for up to 7 days (an A2A push, an MCP task completion, a GitHub or payment webhook, another agent) and forwards each message to your webhook in a signed envelope, or lets you poll. The durable recipient a finished session cannot be. Up to 200 messages of 64KB, optional shared-secret header. One-time $0.10.
