Upstash Context7 SDK

⚠️ 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LLMs rely on outdated or generic training data about the libraries you use.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
const libraries = await client.searchLibrary(
  "I need to build a UI with components",
  "react"
);
console.log(libraries[0].id); // "/facebook/react"

// Get documentation as JSON array (default)
const docs = await client.getContext("How do I use hooks?", "/facebook/react");
console.log(docs[0].title, docs[0].content);

// Get documentation context as plain text
const context = await client.getContext(
  "How do I use hooks?",
  "/facebook/react",
  { type: "txt" }
);
console.log(context);

Configuration

Environment Variables

You can set your API key via environment variable:

Then initialize without options:
