# Context7 Documentation Lookup

Retrieve current documentation and code examples for any programming library directly from the source.

**Prerequisite:** Set `CONTEXT7_API_KEY` environment variable.

## API Quick Reference

| Endpoint | Purpose |
| -------- | ------- |
| `/api/v2/libs/search` | Find libraries by name |
| `/api/v2/context` | Get documentation for a library |

## Usage

### Search Libraries

```bash
curl "https://context7.com/api/v2/libs/search?libraryName=react&query=hooks" \
  -H "Authorization: Bearer $CONTEXT7_API_KEY"
```

Returns library IDs, descriptions, and metadata for matching libraries.

### Get Documentation

```bash
# JSON format (default)
curl "https://context7.com/api/v2/context?libraryId=/facebook/react&query=useEffect" \
  -H "Authorization: Bearer $CONTEXT7_API_KEY"

# Text format (for LLM prompts)
curl "https://context7.com/api/v2/context?libraryId=/facebook/react&query=useEffect&type=txt" \
  -H "Authorization: Bearer $CONTEXT7_API_KEY"

# Specific version
curl "https://context7.com/api/v2/context?libraryId=/vercel/next.js/v15.1.8&query=app%20router" \
  -H "Authorization: Bearer $CONTEXT7_API_KEY"
```

## Workflow

Think step-by-step when using Context7:

1. **Search first** - Find the correct library ID using the search endpoint
2. **Query docs** - Use the library ID with the context endpoint to get relevant documentation
3. **Refine if needed** - Use specific queries or version parameters to narrow results

## When to Use Each Endpoint

| Use `/libs/search` | Use `/context` |
| ------------------ | -------------- |
| Finding library IDs | Querying documentation |
| Exploring available libraries | Getting code examples |
| Unknown or ambiguous library name | You have a library ID |

## Common Library IDs

| Library | ID |
| ------- | -- |
| React | `/facebook/react` |
| Next.js | `/vercel/next.js` |
| Prisma | `/prisma/prisma` |
| Supabase | `/supabase/supabase` |
| TailwindCSS | `/tailwindlabs/tailwindcss` |
