Polygon ID Verifier SDK is one of 17 APIs that [Polygon ID](https://apis.io/providers/polygon-id/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Verification, Zero-Knowledge Proofs, Authentication, On-chain Verification, and Off-chain Verification. The published artifact set on APIs.io includes API documentation and a GitHub repository.

The Verifier SDK enables web2 and web3 applications to authenticate users based on verifiable credentials without accessing the underlying personal data. Verifiers compose ZK queries using the Query Builder, generate QR codes or Universal Links, and receive zero-knowledge proofs from user wallets. Supports both off-chain verification (server-side) and on-chain verification via Polygon smart contracts.
