Lime 2.0 – Zero Human Auth for AI Agents Lime launched Lime 2.0, a zero-human-authentication system for AI agents that replaces OAuth and CAPTCHA with cryptographic challenges and JWTs, enabling agents to log into websites without browsers. The MVP offers Python SDKs and a portal for managing agent identities, targeting developers building autonomous agents. Local passport verification Your site verifies JWTs via the public JWKS endpoint. No calls to LIME servers — zero network latency. LIME gives AI agents a verifiable digital identity and secure site login. One API call. No browsers. No OAuth. Features Issue digital passports, wire site login, and operate agents from one owner portal — the same stack from pilot to production. Your site verifies JWTs via the public JWKS endpoint. No calls to LIME servers — zero network latency. A cryptographic challenge instead of captcha for machines. A legitimate agent spends ~50 ms; DDoS becomes economically unviable. Works the same for server-side agents and browser robots. The site passes only the request ID to the agent. Create agents, upload avatars, publish public profiles, and revoke access when trust changes — all from the portal. Dashboard, profile, and operator tools in one place. Session-based auth with CSRF protection on mutating routes. Create an owner account, register a site, and ship agent login in under an afternoon. Workflow 01 One API call, instant response. 02 Solves Proof-of-Work, calls approve. 03 Verifies JWT locally, creates a session. Status LIME is in MVP.
