# Base API

Base endpoints use EVM JSON-RPC.

## Endpoint

| Item | Value |
| --- | --- |
| Network | Base Mainnet |
| Protocol | EVM JSON-RPC 2.0 |
| Chain ID | `8453` (`0x2105`) |
| Public HTTPS | `https://base-rpc.blockreq.com/v1/rpc/public` |
| Private HTTPS | `https://base-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000000` |
| WSS | `wss://base-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000000` when enabled |

## Core Methods

Base uses the shared [EVM JSON-RPC Methods](https://blockreq.com/docs/build/api-reference/evm-methods/index.md) catalog.

| Capability | Methods |
| --- | --- |
| Latest state | `eth_chainId`, `eth_blockNumber`, `eth_call`, `eth_getBalance` |
| Archive/proof | `eth_getProof`, old-block `eth_getCode`, old-block `eth_getStorageAt` |
| Logs | `eth_getLogs`, `eth_getFilterLogs` |
| Trace/debug | `trace_block`, `trace_filter`, `trace_transaction`, `debug_traceCall`, `debug_traceTransaction` |

Archive and trace methods require a route with matching provider capability.
