Know Your Human (KYH)

Problem Statement
As AI agents gain the ability to transact autonomously on Celo - sending remittances, taking loans, voting in DAOs - there's no lightweight, composable way to verify that a wallet belongs to a real, unique human. Existing KYC tools are built for banks: expensive ($5+ per check), document-heavy, off-chain, and impossible to reuse. Every new dApp forces the same human through verification again. The credentials don't travel. The data gets stored on corporate servers. The verification logic is opaque hard-coded rules. The result: sybil attacks in governance, regulatory gaps in DeFi, exclusion of the unbanked, and growing piles of personal data in breach-prone databases. KYH solves this with tiered verification (free to $0.75), zero-knowledge proofs, private AI reasoning that retains nothing, and on-chain credentials that any agent reads for free forever.
KYH is a unified identity verification gateway for AI agents on Celo. Zero-knowledge proofs, private AI reasoning via Venice, on-chain credentials via EAS, structured claims layer with IPFS persistence. Verify a human in 3 API calls: 1. GET /api/check/0xABC - is this wallet verified? Returns structured claims for free. 2. POST /api/verify - start verification (returns 402) 3. Pay cUSD via x402, human completes verification, EAS attestation issued, evidence pinned to IPFS. Four tiers: - Reputation (free): onchain activity scoring via Human Passport - Document ($0.01): ZK passport proof via Self Protocol NFC - Biometric ($0.25): liveness + face match + gov ID via Didit - Full KYC ($0.75): Self passport + Didit biometric + AML/sanctions Key innovations: - Venice AI as private reasoning engine: holistic pass/fail decisions, zero data retention - Two-layer credential design: lean on-chain attestation (permanent) + extensible off-chain claims layer (over18, uniqueHuman, notSanctioned, queryable via free API) - Evidence pinned to IPFS via Pinata, hash stored as evidenceRef in attestation - ENS integration: every endpoint accepts ENS names, enriches responses with ENS name + avatar - x402 micropayments: no API keys, no sign-ups, wallet IS the identity - Self Agent ID: verified agents get 20% off all paid tiers - Honest tiers: each documents what it proves AND what it doesn't EAS Schema (Celo mainnet): uint8 level, string provider, bool demoMode Schema UID: 0x23b867f11eb49a6d94a6490e11aa2c4fd2dbbda5950b8444281ed2953daad5ab Tech: Next.js 14, TypeScript, Celo, EAS, Venice AI (llama-3.3-70b), Self Protocol, Self Agent ID, Human Passport, Didit, x402, ERC-8004 (#24212), ENS, IPFS/Pinata, Vercel.

Plans to continue
Planning to add more identity providers (WorldID), IPFS/Arweave persistence for evidence, smart contract oracle for on-chain claims queries, and Redis-backed verification store. Interested in Celo ecosystem grants.
