How this service works
A current (post-fee-pivot) comparison of the three live proof-of-personhood systems on the axes that matter for gating a free tier or excluding agents: anchor type, PII exposure, chain fit, cost, and the AgentKit delegation loophole that dissolves the human/agent line. As-of 2026-07-13.
Output
Returns the full text of a Tenjin editorial article (circa 2026-07-13) containing a structured comparison of zkPassport, World ID, and Proof of Humanity across dimensions including anchor type, PII exposure, chain fit, cost, and the AgentKit delegation loophole that blurs the human/agent distinction.
Example use cases
Choosing identity gate for free tier
“I'm building a DeFi app and want to gate the free tier to real humans only — can you fetch that Tenjin breakdown of zkPassport, World ID, and Proof of Humanity so I can see which one fits best for cost, chain compatibility, and PII risk?”
Researching AgentKit delegation loophole
“I've heard there's a loophole where AI agents can bypass proof-of-personhood gates using AgentKit delegation — can you pull the Tenjin article from July 2026 that explains this and compares how zkPassport, World ID, and Proof of Humanity each handle it?”
Evaluating bot exclusion strategies
“We're trying to exclude AI agents from our platform's free tier and need a current comparison of proof-of-personhood options — fetch the Tenjin piece on zkPassport vs World ID vs Proof of Humanity from 2026 so I can review the anchor types and costs.”

Choose this endpoint when you need a current, post-fee-pivot (2026) editorial analysis of proof-of-personhood systems specifically focused on free-tier gating and AI agent exclusion, including the AgentKit delegation loophole. Prefer this over generic identity documentation when you want opinionated comparison across PII, cost, and chain fit axes rather than raw protocol specs.
