--- title: "Robinhood Chain Mainnet API" description: "Robinhood Chain Mainnet JSON-RPC 端点与方法参考" url: "https://blockreq.com/docs/zh-cn/build/api-reference/robinhood/" --- # Robinhood Chain Mainnet API Robinhood Chain Mainnet 端点使用 EVM JSON-RPC Core API。可以先用公开端点试用方法；[创建端点](https://blockreq.com/docs/zh-cn/getting-started/create-endpoint/index.md)即可获得带 API 密钥的私有 URL。 ## 端点 | 项目 | 值 | | --- | --- | | 网络 | Robinhood Chain Mainnet（主网） | | Chain ID | `4663`（`0x1237`） | | 公开 HTTPS | `https://robinhood-mainnet-rpc.blockreq.com/v1/rpc/public` | | 私有 HTTPS | `https://robinhood-mainnet-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000000` | | 公开 WSS | `wss://robinhood-mainnet-rpc.blockreq.com/v1/rpc/public` | | 私有 WSS | `wss://robinhood-mainnet-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000000` | 这些 URL 使用产品路径 `/v1/rpc`，后接 `/public` 或你的 API 密钥。各方法如何计数见 [Request Counting](https://blockreq.com/docs/zh-cn/pricing/request-counting/index.md)。 ##
