About beamrpc.com
Beam is an independent, third-party provider of a free, public JSON-RPC endpoint for the Arc mainnet. Designed for straightforward access, its service requires no API key or signup: users can copy the endpoint or add Arc to a compatible wallet. Beam supports standard JSON-RPC over HTTPS and WebSocket, including subscriptions to new heads and logs through eth_subscribe, making it suitable for wallets, scripts, and decentralized applications.
The service advertises a limit of 300 requests per second per IP and says read requests are handled by a node it operates at the tip of the chain, close to the network. Beam also provides a live status page with the current block height and observed block time, along with documentation and privacy information. For manual wallet configuration, it lists the network name as Arc, chain ID 5042, and currency symbol USDC, as well as the HTTPS and WebSocket URLs.
