The platform

Six primitives.
One credential.

Every tool you need to build on proof of humanity — from a single npm install to enterprise ZK infrastructure.

OAuth 2.0

Sign in with HumanLayer

Like Sign in with Google — but instead of proving you have an email, you prove you're human. Drop in one button. Get back a signed JWT with wallet, score, and tier.

humanlayer.network/verify

REST API

Human Verification API

One endpoint. Pass a wallet address, get back a verified human status, Human Score, and tier. Works with any stack. Open CORS. No API key needed for free tier.

/v1/verify/:wallet

Score API

Reputation Layer

Portable trust and identity scoring. Every verified human has a Human Score from 0–144. Gate access by tier, filter by score, or build reputation-weighted systems.

/api/identity/:wallet/rank

Privacy layer

ZK Infrastructure

UltraPlonk zero-knowledge proofs verified on zkVerify. Users prove they meet a threshold without revealing their score. Mathematically private by design.

One line of HTML. Show a verified human badge next to any wallet address on explorers, trading apps, or your own platform. Free, no API key, open CORS.

/v1/badge/:wallet
