Output
A humanity score integer between 0 and 255, an optional boolean 'passes' field indicating whether the wallet meets the requested minimum score, and per-method boolean verdicts for the named verification methods (e.g. telegram, apple, g2fa) — no raw verification data is returned, only ZK-style verdicts.
Example use cases
Example prompt
“Check whether the wallet 0x4a8f...c3d2 is a real human using Twin3's KYA — I want a humanity score out of 255 and need it to pass a minimum score of 105, also check if they've verified via telegram and apple.”
Technical details
Endpoint
POSThttps://kya.twin3.ai/v1/human?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify whether an EVM wallet address belongs to a real human — especially for sybil resistance in airdrops, DAO voting, or gating access to Web3 services. It is the right choice when you want a numeric humanity score with optional threshold check, or want to confirm specific verification methods (Telegram, Apple ID, 2FA) without needing to enumerate the full verification stack. Prefer it over generic on-chain reputation checks because it is backed by 141,871 Soulbound Tokens and a canonical off-chain humanity registry that never exposes raw verification data.
Side effects
- Invalid or malformed EVM wallet address returns an error
- Unknown or unsupported check method name returns an error or null verdict
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Wallet not found in registry returns score of 0 and passes=false
- Rate limiting or quota exceeded returns a 429 error
