How this service works
Human verification for AI agents — proof of humanity, sybil resistance, and 'is this wallet a real person' answers in one paid call. Returns two ZK-style outputs about any EVM wallet: (1) total humanity score 0-255 (15 = baseline reCAPTCHA, 45 = + Google OAuth, 70 = + Apple ID, 105 = + 2FA, 255 = full stack), with optional `min_score=N` for a yes/no `passes` verdict; (2) per-method verification check via `check=telegram,apple,g2fa,...` — buyer must NAME the methods to ask about, we never enumerate the full set. Backed by 141,871 Twin Matrix Soulbound Tokens on BNB Chain plus the canonical humanity registry off-chain. The underlying verification list never leaves Twin3 — only verdicts.
Output
Returns a JSON object containing: (1) a humanity score integer 0-255 reflecting the depth of verification (15=reCAPTCHA, 45=+Google OAuth, 70=+Apple ID, 105=+2FA, 255=full stack); (2) optionally a `passes: bool` if min_score was set; (3) a `verifications` map of {method: bool} for each explicitly requested verification method (e.g. telegram, apple, g2fa, worldid); (4) optionally `verified_at` SBT mint timestamp and `dimensions_filled` profile completeness count. No raw verification data is exposed — only verdicts.
Example use cases
Example prompt
“Can you check if the wallet 0x1234567890abcdef1234567890abcdef12345678 is a real human — give me their humanity score and whether they pass a minimum score of 45, and also check if they've verified with Google and Telegram?”
Technical details
Endpoint
GEThttps://human.twin3.ai/v1/human?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify whether an EVM wallet belongs to a real, unique human — especially in airdrop gating, DAO voting, DeFi access control, or anti-bot workflows. Prefer it over social-proof-only checks when you need a numeric humanity score backed by on-chain Soulbound Tokens. Choose it when minimal-disclosure is required — you get only verdicts, never raw personal data. It is the right choice when you need to combine multiple verification signals (reCAPTCHA, OAuth, Apple ID, 2FA, Worldcoin) into a single score in one API call.
Side effects
- Invalid wallet address format (not 0x-prefixed 40 hex chars) → 400 Bad Request
- Wallet not found in Twin3 registry → score of 0 or empty verifications
- min_score value outside 0-255 range → 400 validation error
- Unrecognized check method names → partial or empty verifications map
- Payment not provided or insufficient USDC → 402 Payment Required
- Rate limiting or upstream registry unavailability → 429 or 503
