# Context7

## Overview

This skill enables retrieval of current documentation for software libraries and components by querying the Context7 API via curl. Use it instead of relying on potentially outdated training data.

## Workflow

### Step 1: Search for the Library

To find the Context7 library ID, query the search endpoint:

```bash
curl -s "https://context7.com/api/v2/libs/search?libraryName=LIBRARY_NAME&query=TOPIC" | jq '.results[0]'
```

**Parameters:**
- `libraryName` (required): The library name to search for (e.g., "react", "nextjs", "fastapi", "axios")
- `query` (required): A description of the topic for relevance ranking

**Response fields:**
- `id`: Library identifier for the context endpoint (e.g., `/websites/react_dev_reference`)
- `title`: Human-readable library name
- `description`: Brief description of the library
- `totalSnippets`: Number of documentation snippets available

### Step 2: Fetch Documentation

To retrieve documentation, use the library ID from step 1:

```bash
curl -s "https://context7.com/api/v2/context?libraryId=LIBRARY_ID&query=TOPIC&type=txt"
```

**Parameters:**
- `libraryId` (required): The library ID from search results
- `query` (required): The specific topic to retrieve documentation for
- `type` (optional): Response format - `json` (default) or `txt` (plain text, more readable)

## Examples

### React hooks documentation

```bash
# Find React library ID
curl -s "https://context7.com/api/v2/libs/search?libraryName=react&query=hooks" | jq '.results[0].id'
# Returns: "/websites/react_dev_reference"

# Fetch useState documentation
curl -s "https://context7.com/api/v2/context?libraryId=/websites/react_dev_reference&query=useState&type=txt"
```

### Next.js routing documentation

```bash
# Find Next.js library ID
curl -s "https://context7.com/api/v2/libs/search?libraryName=nextjs&query=routing" | jq '.results[0].id'

# Fetch app router documentation
curl -s "https://context7.com/api/v2/context?libraryId=/vercel/next.js&query=app+router&type=txt"
```

### FastAPI dependency injection

```bash
# Find FastAPI library ID
curl -s "https://context7.com/api/v2/libs/search?libraryName=fastapi&query=dependencies" | jq '.results[0].id'

# Fetch dependency injection documentation
curl -s "https://context7.com/api/v2/context?libraryId=/fastapi/fastapi&query=dependency+injection&type=txt"
```

## Tips

- Use `type=txt` for more readable output
- Use `jq` to filter and format JSON responses
- Be specific with the `query` parameter to improve relevance ranking
- If the first search result is not correct, check additional results in the array
- URL-encode query parameters containing spaces (use `+` or `%20`)
- No API key is required for basic usage (rate-limited)
