Endpoints

How to connect to EthSync over HTTPS and live WebSocket for every chain.

How it works

Connect

Point your app at our JSON-RPC endpoint over HTTPS, or use the live WebSocket streams — all three chains, one door.

Get your key

Authenticate with an x-api-key header. Free keys open at launch — no card required to start.

Go fast

Dedicated bare-metal nodes, low-latency peering and high availability for Robinhood Chain, Ethereum and ApeChain.

RPC Access

JSON-RPC over HTTPS and live WebSocket for every chain. Authenticate with an x-api-key header — free keys at launch.

Try the public endpoint — live now

curl https://rpc.ethsync.xyz/rh \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

# latest block — Robinhood Chain (with your key)$ curl https://rpc.ethsync.xyz/rh \
  -H "Content-Type: application/json" \
  -H "x-api-key: <YOUR_KEY>" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

Authentication goes in the x-api-key header.
