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.

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 Use it instead of relying on potentially outdated training data.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

What it does

Queries the Context7 API to fetch current documentation for software libraries and frameworks, bypassing potentially stale training data. Useful for looking up API signatures, code examples, and feature documentation for any programming library from React to FastAPI.

Generated from the current SKILL.md.

Frequently asked

Does this skill work offline or require internet access?
The skill requires internet access to query the Context7 API. It cannot function without a live connection to context7.com.
What libraries and frameworks does Context7 support?
The skill can search any library indexed by Context7, including React, Next.js, FastAPI, Axios, and others. Use the search endpoint to check if a specific library is available.
Do I need an API key to use this skill?
No API key is required for basic usage, though requests are rate-limited. The skill queries the Context7 API directly via curl.
How current is the documentation retrieved by this skill?
Documentation freshness depends on Context7's update frequency for each library. The skill fetches whatever version Context7 currently hosts, which is typically more current than training data.
