KeyID.ai – Free email and phone infrastructure for AI agents

Summary: KeyID.ai provides AI agents with real email addresses, phone numbers, and verification handling via a single API call without human setup or API keys. Agents self-provision using Ed25519 keypairs to send and receive emails, extract OTP codes, follow verification links, complete signups with browser state persistence, and generate TOTP 2FA codes.

What it does

KeyID.ai enables AI agents to self-provision communication credentials and manage multi-step signup flows including email and SMS verification and TOTP generation through an API. It supports integration with Claude, Cursor, Windsurf, and offers JS and Python SDKs.

Who it's for

It is designed for developers building AI agents that require real email and phone infrastructure to automate service signups and verifications.

Why it matters

It solves the lack of free, automated infrastructure for AI agents to obtain and manage real communication credentials during multi-step registration processes.
