# context7.com URL Patterns

## Topic-Specific URLs (Priority #1)

**Pattern:** `https://context7.com/{path}/llms.txt?topic={keyword}`

**When to use:** User asks about specific feature/component

**Examples:**
```
shadcn/ui date picker
→ https://context7.com/shadcn-ui/ui/llms.txt?topic=date

Next.js caching
→ https://context7.com/vercel/next.js/llms.txt?topic=cache

Better Auth OAuth
→ https://context7.com/better-auth/better-auth/llms.txt?topic=oauth

FFmpeg compression
→ https://context7.com/websites/ffmpeg_doxygen_8_0/llms.txt?topic=compress
```

**Benefits:** Returns ONLY relevant docs, 10x faster, minimal tokens

## General Library URLs (Priority #2)

**GitHub repos:** `https://context7.com/{org}/{repo}/llms.txt`

**Websites:** `https://context7.com/websites/{normalized-path}/llms.txt`
