Ethereum API

Ethereum endpoints use the EVM JSON-RPC Core API over HTTPS and, when enabled for the route, WSS.

Endpoint

Item	Value
Network	Ethereum Mainnet
Protocol	EVM JSON-RPC 2.0
Chain ID	`1` (`0x1`)
Public HTTPS	`https://ethereum-rpc.blockreq.com/v1/rpc/public`
Private HTTPS	`https://ethereum-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000`
WSS	`wss://ethereum-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000` when enabled

Core Methods

Use the EVM JSON-RPC Methods catalog for request shapes and Request Counting for billing.

Category	Methods
Chain and blocks	`eth_chainId`, `eth_blockNumber`, `eth_getBlockByNumber`, `eth_getBlockByHash`
State and archive	`eth_getBalance`, `eth_getCode`, `eth_getStorageAt`, `eth_call`, `eth_getProof`
Logs and transactions	`eth_getLogs`, `eth_getTransactionByHash`, `eth_getTransactionReceipt`
All history / execution replay	`debug_traceCall`, `debug_traceTransaction`, `debug_traceBlockByNumber`, `trace_block`, `trace_call`, `trace_filter`, `trace_transaction`
Subscriptions	`eth_subscribe`, `eth_unsubscribe` over WSS

Archive and All History

Ethereum historical state calls require an archive-capable route. This includes old-block eth_call, old-block balance/code/storage/nonce reads, eth_getProof, and debug_* or trace_* replay methods. eth_getLogs is history-oriented but is usually served by log/index-capable lanes rather than full archive state.

Debug and Trace

debug_*, trace_*, and txpool_* are available on every paid plan when the Ethereum route supports the method. The Free grant does not include them.
