About context7

context7 is a skill for retrieving current software library documentation through the Context7 API. It guides agents through finding a library and requesting topic-specific documentation instead of relying on potentially outdated training data.

Key features

  1. 01Search for library identifiers
  2. 02Fetch topic-specific documentation
  3. 03Use curl and jq examples

Use cases

  1. 01Check current React hooks documentation
  2. 02Look up Next.js routing guidance
  3. 03Retrieve FastAPI dependency injection details

Install

Copy the command and run it in a terminal.

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 Use it instead of relying on potentially outdated training data.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:

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:

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
# 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
# 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
# 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)
