BitGo Express API

openapi: 3.0.1

  title: BitGo Platform API
  description: >-
    Representative specification of the BitGo Platform REST API v2 for
    institutional digital-asset custody. Covers wallets, addresses,
    transactions and transfers, keychains, webhooks, wallet policies, staking,
    trading and settlement over the Go Network, and enterprise / user surfaces.
    Most endpoints are namespaced under a coin (for example `btc`, `eth`,
    `hteth`) via the `{coin}` path parameter. Authentication uses a Bearer
    access token. Transaction-signing operations that require private-key
    material are typically issued against a self-hosted BitGo Express proxy.
