# 为您的项目创建区块链 API

##  区块链 API 端点

JSON-RPC 端点

```
http://api.chainup.net/<PROTOCOL>/<NETWORK>/<TOKEN>
```

Websocket 端点

```
ws://api.chainup.net/ws/<PROTOCOL>/<NETWORK>/<TOKEN>
```

## 专用节点端点

SON-RPC 端点

```
http://<YOUR-NODE-ID>.blockchain.info/<TOKEN>
```

Websocket 端点

```
ws://<YOUR-NODE-ID>.blockchain.info/ws/<TOKEN>
```

## 使用项目 ID

&#x20;以太坊 API 要求在您的请求流量中包含有效的项目 ID。此标识符必须附加到请求 URL。以下示例显示了如何针对 HTTPS 或 WebSocket 请求执行此操作：

{% tabs %}
{% tab title="HTTP" %}

```
curl http://api.chainup.net/ethereum/mainet/<TOKEN> \
    -X POST \
    -H "Content-Type: application/json" \
    -H "CONSISTENT-HASH: true" \
    -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
```

{% endtab %}

{% tab title="WebSocket" %}

```
wscat -c ws://api.chainup.net/ws/ethereum/mainet/<TOKEN>
> {"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}
```

{% endtab %}
{% endtabs %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.chainupcloud.com/zhong-wen/qu-kuai-lian-api/overview/create-blockchain-api-for-your-project.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
