context7
Retrieve up-to-date documentation for software libraries, frameworks, and components via the Context7 API. This skill should be used when looking up documentation for any programming library or framework, finding code examples for specific APIs or features, verifying correct usage of library functions, or obtaining current information about library APIs that may have changed since training.
Best use case
context7 is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

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 Use it instead of relying on potentially outdated training data.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