Uniblock Market Data API

openapi: 3.2.0
info:
  title: Uniblock Direct Direct Pass-Through Market Data API
  description: The Uniblock Direct API gives developers pass-through access to provider-specific endpoints exactly as offered by upstream blockchain data providers. Requests follow the pattern of specifying the provider and optional prefix in the URL path, while still benefiting from Uniblock's routing, retry, and failover infrastructure. Results are returned exactly as they would be if the first-party provider endpoint was called directly. This is intended for use cases where a specific method is not yet abstracted into the Unified API.
