⚠️ Work in Progress: This SDK is currently under active development. The API is subject to change and may introduce breaking changes in future releases.

@upstash/context7-sdk is an HTTP/REST based client for TypeScript, built on top of the Context7 API.

Why Context7?

LLMs rely on outdated or generic training data about the libraries you use. This leads to:

Code examples based on year-old training data
Hallucinated APIs that don't exist
Generic answers for old package versions

Context7 solves this by providing up-to-date, version-specific documentation and code examples directly from the source. Use this SDK to:

Build AI agents with accurate, current documentation context
Create RAG pipelines with reliable library documentation
Power code generation tools with real API references

Quick Start

Install

npm install @upstash/context7-sdk

Get API Key

Get your API key from Context7

Basic Usage

import { Context7 } from "@upstash/context7-sdk";

const client = new Context7({
  apiKey: "<CONTEXT7_API_KEY>",
});

// Search for libraries in the Context7 database
const libraries = await client.searchLibrary("react");
console.log(libraries.results);

// Query the documentation with specific topics
const filteredDocs = await client.getDocs("/facebook/react", {
  topic: "hooks",
  limit: 10,
  page: 1,
});

// Get documentation as JSON by default
const docs = await client.getDocs("/vercel/next.js");
console.log(docs.snippets);

// Get documentation as TXT
const codeDocs = await client.getDocs("/mongodb/docs", {
  format: "txt",
  mode: "code",
});
console.log(codeDocs.content);

Configuration

Environment Variables

You can set your API key via environment variable:

Then initialize without options:
