context7

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 Use it instead of relying on potentially outdated training data. ### 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)
