  title: Bakkt Crypto Solutions Accounts Instruments API
  version: '2.0'
  description: The Bakkt Crypto Solutions API is a REST-based API that provides a platform for clients, so their investors can purchase, hold, sell, and transfer digital assets. Clients must have authorization to use the APIs, secure endpoints, and facilities to ensure safe, fast execution and tracking of orders. Users must specify all date and time units using epoch time in UTC. The URL path includes a version number to indicate major versions which retain backward compatibility to other URLs with the same version prefix. This document is reconstructed by the API Evangelist enrichment pipeline from the per-endpoint OpenAPI fragments Bakkt publishes on its ReadMe developer hub (bakkt.readme.io); it merges the Crypto Solutions (/apex-crypto/api/v2) and Fiat/Partner (/partner/v1) endpoint families.
