One Trading Futures API

  title: One Trading Fast Funding Futures API
  version: '1.0'
  description: 'REST API for the One Trading exchange ("Fast API"). Public market-data endpoints (currencies, instruments, order book, candlesticks, market ticker, fees, funding rates, server time) require no authentication. Account, trading and futures endpoints require a Bearer API token with the appropriate permission scope (Read / Trade / Withdraw / SUBACCOUNT_TRANSFER).

    Provenance: this specification was reconstructed by API Evangelist from the provider''s public documentation index (https://docs.onetrading.com/llms.txt) and from live responses of the public endpoints. Request/response schemas for public endpoints reflect real observed payloads; authenticated operations are modeled from the documented operation catalog. It is not the provider''s official machine-readable contract.'
