Archive EVM JSON-RPC Example

Archive-capable EVM routes support deep state, proof, log, debug, and trace workloads according to plan and chain capability.

curl "https://arbitrum-one-rpc.blockreq.com/v1/rpc/public" \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_getProof","params":["0x0000000000000000000000000000000000000000",[],"0x1"],"id":1}'

Use paid endpoints for `debug_*`, `trace_*`, and other heavy archive methods; Free endpoints do not include debug, trace, or txpool access.

Every method counts as 1 Request: eth_getProof and trace_block cost the same as eth_blockNumber.

Manage RPC access from one dashboard

Create endpoints, rotate keys, and monitor usage across supported chains without hardcoding chain support into the frontend.
