Arcfeed Documentation
Arcfeed is real-time cryptocurrency market data infrastructure. It aggregates normalized trade data from 10+ exchanges and delivers it to your application via two products:
- Stream API — a server-side streaming gRPC (Connect RPC) endpoint at
stream.arcfeed.finance:443. Subscribe to any combination of trading pairs and exchanges. Receive trades as they happen. - BigQuery — direct access to historical trade data in your own GCP project. Standard SQL, ML-ready schemas, no ETL pipelines to maintain.
