Context7

1---2name: context73description: 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.4---5 6# Context77 8## Overview9 10This 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 Use it instead of relying on potentially outdated training data.11 12## Workflow13 14### Step 1: Search for the Library15 16To find the Context7 library ID, query the search endpoint:17 18```bash19curl -s "https://context7.com/api/v2/libs/search?libraryName=LIBRARY_NAME&query=TOPIC" | jq '.results[0]'20```21 22**Parameters:**23- `libraryName` (required): The library name to search for (e.g., "react", "nextjs", "fastapi", "axios")24- `query` (required): A description of the topic for relevance ranking25 26**Response fields:**27- `id`: Library identifier for the context endpoint (e.g., `/websites/react_dev_reference`)28- `title`: Human-readable library name29- `description`: Brief description of the library30- `totalSnippets`: Number of documentation snippets available31 32### Step 2: Fetch Documentation33 34To retrieve documentation, use the library ID from step 1:35 36```bash37curl -s "https://context7.com/api/v2/context?libraryId=LIBRARY_ID&query=TOPIC&type=txt"38```39 40**Parameters:**41- `libraryId` (required): The library ID from search results42- `query` (required): The specific topic to retrieve documentation for43- `type` (optional): Response format - `json` (default) or `txt` (plain text, more readable)44 45## Examples46 47### React hooks documentation48 49```bash50# Find React library ID51curl -s "https://context7.com/api/v2/libs/search?libraryName=react&query=hooks" | jq '.results[0].id'52# Returns: "/websites/react_dev_reference"53 54# Fetch useState documentation55curl -s "https://context7.com/api/v2/context?libraryId=/websites/react_dev_reference&query=useState&type=txt"56```57 58### Next.js routing documentation59 60```bash61# Find Next.js library ID62curl -s "https://context7.com/api/v2/libs/search?libraryName=nextjs&query=routing" | jq '.results[0].id'63 64# Fetch app router documentation65curl -s "https://context7.com/api/v2/context?libraryId=/vercel/next.js&query=app+router&type=txt"66```67 68### FastAPI dependency injection69 70```bash71# Find FastAPI library ID72curl -s "https://context7.com/api/v2/libs/search?libraryName=fastapi&query=dependencies" | jq '.results[0].id'73 74# Fetch dependency injection documentation75curl -s "https://context7.com/api/v2/context?libraryId=/fastapi/fastapi&query=dependency+injection&type=txt"76```77 78## Tips79 80- Use `type=txt` for more readable output81- Use `jq` to filter and format JSON responses82- Be specific with the `query` parameter to improve relevance ranking83- If the first search result is not correct, check additional results in the array84- URL-encode query parameters containing spaces (use `+` or `%20`)85- No API key is required for basic usage (rate-limited)
