  version: 1.0.0
  description: >-
    The developer API is in beta. Breaking changes may be introduced at any
    time. Programmatic access to MyFundedPerps paper-trading challenge accounts.

    the web trading interface. Every response carries an `X-Request-Id` header
    for support and log correlation.
