- name: SpruceID Sign-In with Ethereum (SIWE) API
  description: Sign-In with Ethereum (SIWE) enables Ethereum accounts to authenticate with off-chain services by signing a
    standardized message format (EIP-4361). SpruceID's SIWE library provides client and server implementations in TypeScript
    for integrating Ethereum wallet-based authentication into web applications. The SIWE-OIDC component wraps SIWE in an OpenID
    Connect Identity Provider, enabling drop-in integration with OAuth 2.0 and OIDC flows. Supported wallets include MetaMask,
    Coinbase Wallet, and any WalletConnect-compatible wallet. ENS domain resolution is included for human-readable usernames.

- name: SpruceID SSI Core Library API
  description: The SpruceID SSI (Self-Sovereign Identity) core library provides a comprehensive Rust API for signing, issuing,
    and verifying W3C Verifiable Credentials and JSON Web Tokens. It supports VC Data Model 1.1 and 2.0, JWT-VC, Data Integrity
    proofs, BBS+ selective disclosure, and a wide range of cryptographic signature suites including EdDSA, secp256k1, P-256,
    and more. The library has undergone a Trail of Bits security audit and serves as the foundation for DIDKit and other SpruceID
    tooling.

  description: SpruceID's OID4VCI (OpenID for Verifiable Credential Issuance) Rust library implements the OpenID4VC credential
    issuance protocol, enabling credential issuers to deliver W3C Verifiable Credentials to holder wallets. The protocol extends
    OAuth 2.0 with credential endpoint flows including pre-authorized code flow and authorization code flow. Supported credential
    formats include JWT-VC, LDP-VC, SD-JWT VC, and ISO/IEC 18013-5 mobile documents (mDL). Used as the issuance layer in the
    SpruceKit mobile SDK.

    protocol, enabling verifier applications to request and receive verifiable credentials from holder wallets. The library
    handles presentation definitions, selective disclosure, and cryptographic proof verification. Supported credential formats
    include JWT-VC, LDP-VC, SD-JWT VC, and ISO/IEC 18013-5 mobile driver's licenses (mDL) for offline presentation. Integrates
    with SpruceKit mobile SDKs for iOS and Android wallet apps.
