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LLMs rely on outdated or generic training data about the libraries you use.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

$3

``bash
npm install @upstash/context7-sdk
`

$3

Get your API key from Context7

Basic Usage

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

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

// 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

$3

You can set your API key via environment variable:

`sh
CONTEXT7_API_KEY=ctx7sk-...
`

Then initialize without options:

`ts
const client = new Context7();
`
