The Klutch Public API is a GraphQL API for the Klutch programmable credit card. It exposes enriched transaction history with filtering, cursor pagination and group-by aggregation; user-defined transaction categories; virtual and physical card lifecycle (create, activate, edit, lock, unlock, cancel); server-side transaction rules (accumulating over a period, accumulating between dates, decline-based-on-filter, day of week, time of day); account balance and revolving loan limits; ACH card payments and transfer sources; and Mini App panel rendering. Authentication is a bearer session token minted from a developer client id and secret key, or OAuth 2.1 authorization code with PKCE for user-consented agents.
