If the exact page cannot be found, you can still retrieve the information using the documentation query interface.

### Option 1 — Ask a question (recommended)

Perform an HTTP GET request on the documentation index with the `ask` parameter:

```
GET https://docs.bit-bank.io/confidential-futures-and-exchange-platform-tech-docs/futures/fee-structure.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

### Option 2 — Browse the documentation index

Full index: https://docs.bit-bank.io/sitemap.md

### Option 3 — Retrieve the full documentation corpus

Full export: https://docs.bit-bank.io/llms-full.txt

Use this to access all content at once and perform your own parsing or retrieval. It will be more expensive.
