# Atoms > Atoms is Cloudflare-native email infrastructure for AI agents: task-scoped, accountless inboxes controlled by Ed25519 and X25519 keys, with correspondence sealed before durable storage. The public API is rooted at https://api.atoms.email/v1. Atoms is under active development. Treat the documented API as an early foundation. The service never receives controller private keys. Ordinary SMTP plaintext is transiently processed by a Cloudflare Email Worker, then stored only as controller-sealed ciphertext in R2. ## Documentation - [API reference](https://atoms.email/api.md): Authentication, endpoint inventory, address proof, and current deployment status. - [Security model](https://atoms.email/security.md): Cryptographic suite, readable metadata, storage guarantees, and the honest SMTP boundary. ## Source - [GitHub repository](https://github.com/atomsfi/atoms-email): Private during early development; access may require authorization. ## Optional - [API health](https://api.atoms.email/health): Live Worker health endpoint.
