About AgentInbox
AgentInbox provides disposable email addresses that software can create on demand. It targets AI agents, QA teams and CI pipelines that need to sign up for services, receive verification emails and carry on with an automated workflow without a human opening a mailbox.
Inboxes are created through a REST API, a Node SDK or MCP tools. Each incoming message is read by an AI-based extractor that isolates one-time passcodes and magic links, supports several languages, and attaches a confidence score so agents and tests only act on data they can trust. Real-time webhooks push events to your own stack, signed with HMAC, and scoped API keys limit access. A dashboard shows volume, latency and extraction accuracy. AgentInbox is a commercial hosted service with a free starting tier and paid plans for higher volume. It is meant for developer workflows rather than everyday personal email.
