# Arc API

Arc endpoints use the EVM JSON-RPC Core API over HTTPS and WSS.

## Endpoint

| Item | Value |
| --- | --- |
| Network | Arc Mainnet |
| Protocol | EVM JSON-RPC 2.0 |
| Chain ID | `5042` (`0x13b2`) |
| Public HTTPS | `https://arc-rpc.blockreq.com/v1/rpc/public` |
| Private HTTPS | `https://arc-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000000` |
| Public WSS | `wss://arc-rpc.blockreq.com/v1/rpc/public` |
| Private WSS | `wss://arc-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000000` |

These URLs use the product path `/v1/rpc` plus `/public` or `BRQ1P0000000000000000000000000000000000000000000000000000000`. Callers use BlockReq HTTP and WSS on this host.

## Core Methods

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

BlockReq does not currently document or guarantee `eth_getProof`, `debug_*`, or `trace_*` on Arc.
