RPC for 4 blockchains with one API key

Every request is served by a full node we run ourselves. One gateway host, one path per chain, each chain in its native protocol — metered in Compute Units.

QuickstartSupported chains
Request
curl https://rpc.nodes.koshelek.ru/eth \
  -H "apikey: $YOUR_API_KEY" \
  -H "content-type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,
       "method":"eth_blockNumber",
       "params":[]}'

Same host for every chain — only the path changes.
