CuteMarkets TypeScript SDK for Real-Time and Historical Options Data

The official TypeScript SDK for CuteMarkets. Use it to access a real-time and historical options data API from Node, server-side Next.js, and modern JavaScript runtimes.

This package focuses on the workflows developers actually search for: options chain API access, historical contracts with as_of, quotes, trades, aggregates, expirations, and lightweight utilities for earnings research and scanner construction.

Use Cases

• Build an options chain scanner in Node or Next.js.
• Reconstruct historical contracts with as_of.
• Estimate implied move around earnings from the ATM straddle.
• Pull quotes, trades, and aggregates into a research or alerting workflow.

Installation

npm install cutemarkets-typescript

Quick Start

import { CuteMarketsClient } from "cutemarkets-typescript";

const client = new CuteMarketsClient({ apiKey: process.env.CUTEMARKETS_API_KEY });

const chain = await client.options.chain("SPY", { limit: 5 });
for (const contract of chain.results) {
  console.log(contract.details?.ticker, contract.implied_volatility);
}

console.log(client.lastRequestId, client.lastRateLimit?.remaining_minute);

Why this SDK instead of raw fetch calls

Raw fetch works, but most developers end up rebuilding the same plumbing in every project: authentication, query serialization, path escaping, response typing, and error handling. This SDK gives you a small typed surface so your application code can focus on chain filtering, historical contract reconstruction, and event-study logic.
