  title: Lithic 3DS Responder Endpoints API
  description: The Lithic API is a card issuing and issuer-processor platform for issuing virtual and physical cards, authorizing and clearing transactions, moving money across ledgered financial accounts, and managing the full card lifecycle - KYC/KYB account holder onboarding, authorization rules and real-time Auth Stream Access (ASA) decisioning, disputes, tokenization into digital wallets, 3DS authentication, ACH payments, book transfers, external payments, settlement reporting, and fraud/transaction monitoring. This document curates the real, published Lithic OpenAPI 3.1 definitions (https://github.com/lithic-com/lithic-openapi) into the endpoint surface referenced by this apis.yml, expressed as OpenAPI 3.0.3 with lightweight response schemas. Requests are authenticated with an API key sent as the raw value of the Authorization header (not a Bearer token).
