# 知识星球智能发布

Publish content to 知识星球 via API or browser automation.

## Authentication

Requires a valid `zsxq_access_token` cookie. Get it by:

1. Open `https://wx.zsxq.com` in browser
2. Login via WeChat QR scan
3. Open DevTools → Application → Cookies → find `zsxq_access_token`
4. Set env var: `export ZSXQ_ACCESS_TOKEN="your_token"`
   Or store in config file (see `references/config.md`)

Token expires. Re-scan QR when API returns 401.

## Content Types

| Type | topic_type | API field | Char limit | Description |
|------|-----------|-----------|------------|-------------|
| 话题 (Talk) | `talk` | `type` | 50,000 chars | General post, text+images+files |
| 问答 (Q&A) | `q&a` | `type` | 50,000 chars | Question format, star-owner can answer |
