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. We invite the first partners for pilot integrations. Join early access and help shape the product with us.

Integration

Python SDK for AI agents. Confirm login in one line.

pip install lime-agents-sdk Python SDK for sites. Auto SSE dispatcher, on_login handlers, passport verify.
