# llms.txt

Webull OpenAPI documentation is published in machine-readable formats to support AI-assisted development. Large Language Models can reference the documentation directly — helping you generate more accurate integration code, troubleshoot faster, and explore the API with AI tools.

## Machine-Readable Documentation (llms.txt)

The documentation follows the [llms.txt](https://llmstxt.org/) standard — a lightweight format that gives LLMs a complete, structured reference of the API.

**Index file:**

[https://developer.webull.hk/apis/llms.txt](https://developer.webull.hk/apis/llms.txt)

## Markdown Access

Every documentation page has a Markdown variant. Append `.md` to any page URL to get the raw Markdown content, ideal for feeding into LLMs, RAG pipelines, or documentation crawlers.

| Page URL | Markdown URL |
|----------|-------------|
| `https://developer.webull.hk/apis/docs/about` | [about.md](https://developer.webull.hk/apis/docs/about.md) |
| `https://developer.webull.hk/apis/docs/trade-api/overview` | [trade-overview.md](https://developer.webull.hk/apis/docs/trade-api/overview.md) |

Fetch Markdown content from the command line:

```bash
curl https://developer.webull.hk/apis/docs/about.md
```

## Integration with AI Tools

### Claude

In [Claude](https://claude.ai), you can add the Webull OpenAPI documentation as a Project Knowledge source:

1. Create or open a **Project** in Claude.
2. In the Project settings, click **Add Content** → **Add from URL**.
3. Paste the llms.txt URL:
   ```
   https://developer.webull.hk/apis/llms.txt
   ```
4. Claude will use the documentation as context for all conversations within that project.

### Cursor

In [Cursor](https://www.cursor.com):

1. Open the command palette (`Command + Shift + P`) and select **Add New Custom Docs**.
2. Paste the llms.txt URL:
   ```
   https://developer.webull.hk/apis/llms.txt
   ```
3. In any AI conversation, use **@Add Context** → **docs** to attach the Webull OpenAPI reference. The AI will use it as context for code generation and Q&A.

### Kiro

In [Kiro](https://kiro.dev), you can add the llms.txt as a steering file or reference it directly in chat using `#URL` to give the AI full context of the Webull OpenAPI documentation.

### ChatGPT

In [ChatGPT](https://chatgpt.com), you can provide the documentation via file upload or custom instructions:

1. Download the llms.txt file or copy its content.
2. In a conversation, click the **attachment** icon and upload the file — or paste the content directly into the chat.
3. For persistent access, add the llms.txt URL to your **Custom Instructions** or use it within a **GPT** as a knowledge source.

### Gemini

In [Google Gemini](https://gemini.google.com), you can reference the documentation directly:

1. Upload the llms.txt file as an attachment in a conversation.
2. Alternatively, paste the raw content or specific sections into the chat for targeted questions.

### More AI Models / Tools

The llms.txt URL works with any tool that accepts external documentation as context — including RAG pipelines, MCP servers, and general-purpose AI coding assistants.
