Inkbox provides a persistent identity layer for AI agents, assigning each a unique email address, phone number, and zero‑knowledge encrypted vault. Developers can integrate mail, voice call, and secret‑storage APIs via Python, TypeScript SDKs or CLI, enabling agents to communicate through real channels and manage credentials securely without prior accounts.

Problem
AI agents often operate without a persistent, verifiable identity, limiting their ability to communicate via standard channels, manage credentials securely, or maintain consistent interactions across sessions.
Solution
Inkbox supplies an identity layer that assigns each AI agent a dedicated email address, phone number, and encrypted vault. Agents can self‑register without a pre‑existing API key, receiving an API key and mailbox after a simple human verification step. The platform offers SDKs for Python, TypeScript, and a CLI, enabling developers to integrate email, voice call, and secret‑storage capabilities directly into their applications. Communication is handled through real email and telephony services, while the vault provides zero‑knowledge encryption for storing API keys, SSH keys, and other sensitive data. Inkbox also supports skill installation for popular coding assistants such as Claude Code and Cursor, allowing agents to instantly access the identity services.
Target Audience
Inkbox is aimed at developers and product teams building AI agents, coding assistants, and enterprise automation solutions that require reliable communication channels and secure secret management.
