Historical Options Data API Comparison: Features, Coverage, and Pricing
1. Massive Options Market Data API

Market Coverage
Massive provides a comprehensive range of options chain data, including Greeks, implied volatility, and trade-level details. This data spans U.S. exchanges, dark pools, OTC markets, and global indices. However, the platform doesn’t specify the full geographic scope of its options data just yet.
Historical Depth and Granularity
For those diving into historical market trends, Massive offers options data going back to 2014. The platform delivers trade-level detail with tick-level precision and supports intraday queries using minute-level aggregation. This makes it a valuable tool for conducting detailed market analyses.
Pricing Model

2. TagX Stock Market API

Market Coverage
TagX’s documentation leaves much to be desired when it comes to market coverage. It doesn’t clearly outline the geographic regions or specific markets it supports, creating uncertainty for potential users.
Historical Depth and Granularity
Another significant gap in the documentation is the lack of information about historical data.

This omission makes it tough for users to assess how well the API aligns with their needs.
Data Types
When it comes to options data, the documentation falls short again. It doesn’t clarify whether elements like option chains, strike prices, expiration dates, or volume metrics are included. This lack of detail could be a dealbreaker for those who rely on comprehensive options data.
Pricing Model
Transparency about pricing is equally crucial, especially for users planning to use the API for backtesting or other intensive applications. Unfortunately, TagX doesn’t publish detailed pricing information or subscription plans. If you’re interested, you’ll need to contact them directly to get specifics. Compared to other providers that offer more thorough disclosures, TagX’s limited documentation may feel like a missed opportunity.

How to Connect APIs with Your Trading Infrastructure
Integrating historical options data APIs into your trading setup requires a combination of reliable hardware and efficient software solutions. A trading-focused VPS (Virtual Private Server) should feature a high-speed network interface to manage real-time data streams, sufficient CPU and RAM to process large datasets, and enough storage to handle historical data archives. Positioning servers close to major exchange data centers can further minimize latency, often reducing it to under 20ms.
Modern APIs provide flexibility with multiple access options tailored to different workflows. RESTful APIs are ideal for retrieving bulk historical data, while WebSocket connections are better suited for real-time updates. For handling large datasets, options like flat file access through S3-compatible interfaces or direct SQL queries can be more efficient than repeated REST calls, helping to avoid I/O bottlenecks. Client libraries – especially those written in Python – make integration easier by allowing you to fetch and process data programmatically with minimal development effort. These tools play a crucial role in building automated data pipelines.
Creating automated data pipelines is straightforward with these libraries. For instance, a trader can use a Python script with the Massive client library to fetch minute-level aggregates for a specific ticker over a defined date range. By scheduling this script using cron, regular data ingestion becomes a seamless process. Since the data is delivered in standardized formats, it’s simple to parse, store, and feed directly into backtesting frameworks. For advanced workflows, AI-driven systems can integrate with market data APIs to streamline analysis further.
When it comes to backtesting, using a VPS with APIs that deliver clean, normalized, institutional-grade data – free of survivorship bias – is critical. This ensures that your historical simulations accurately reflect market conditions, laying the groundwork for dependable strategy development. With extensive historical data and low-latency infrastructure, traders can conduct both high-frequency strategy testing and in-depth historical analysis. QuantVPS offers plans tailored to these needs, from VPS Lite ($59.99/month, 4 cores and 8GB RAM) to Dedicated Servers ($299.99/month, 16+ cores and 128GB RAM), providing the processing power and speed necessary for managing massive datasets.
