Cloud API

The Cloud API allows users to access the bloXroute Blockchain Distribution Network (BDN) without installing or maintaining a local Gateway. It’s ideal for applications that require fast, reliable access to transaction and block data at scale.

Endpoints

Transaction Submission Use: https://api.blxrbdn.com DNS automatically routes requests to the instance closest to your application.

Streaming Data Use a regional endpoint based on your deployment:

• Ethereum: <REGION>.eth.blxrbdn.com

• BSC: <REGION>.bsc.blxrbdn.com

Available Regions

These apply to streaming endpoints and are resolved automatically unless specified:

Region Name	DNS Prefix	Location
US - Virginia	virginia	US East (AWS)
England - London	uk	Europe (AWS)
Singapore	singapore	Asia Pacific (AWS)
Germany	germany	Europe Central (AWS)

Recommended: gRPC Streaming

For each region, streaming is available via WebSocket (WS) or gRPC. gRPC may provide better performance and lower latency compared to WebSocket.

Example (Virginia – Ethereum):

• WebSocket: wss://virginia.eth.blxrbdn.com/ws

• gRPC: virginia.eth.blxrbdn.com:5005
