# Dwellir

> Enterprise-grade blockchain infrastructure platform providing RPC endpoints for 150+ networks with 99.99% uptime SLA. Authenticate HTTP and WebSocket connections with X-Api-Key or a key in the endpoint URL path. Use lowercase x-api-key metadata for gRPC.

HTTP and WebSocket header authentication: X-Api-Key: YOUR_API_KEY
HTTP and WebSocket URL path authentication: https://api-{network}.n.dwellir.com/YOUR_API_KEY
gRPC metadata authentication: x-api-key: YOUR_API_KEY
