While primarily known as a forex and CFD trading platform, OANDA also offers valuable historical crypto data extending back to 2005 for major currency pairs. This long timeline allows for macroeconomic comparisons between traditional and digital assets.
Even free accounts gain access to basic historical datasets, making OANDA an accessible entry point for beginners. The platform includes intuitive analytics views that simplify trend identification without requiring technical expertise.

FXCM: Unique Live Trading Data from Real Accounts
FXCM distinguishes itself by sourcing crypto data directly from live trading accounts within its ecosystem. This origin means the data reflects actual market activity rather than aggregated feeds.
The broker offers three distinct APIs, allowing flexible access based on user needs. While 24/7 support isn’t available, FXCM’s customer service is responsive and knowledgeable.
Premium plans include advanced analytics tools and customizable data fields—useful for algorithmic traders and quantitative analysts. Bespoke solutions can also be requested for specialized use cases.
OKX: Free Historical APIs from a Major Exchange
OKX, one of the world’s largest cryptocurrency exchanges, provides seven free historical data APIs—three for spot markets and four for futures trading.
Some datasets date back only to 2021, but others include all historical records since the platform’s launch. This direct-from-exchange data is particularly valuable for backtesting trading strategies using real order book and trade history.
While OKX doesn’t offer extensive support or pre-built applications like premium vendors, its zero-cost access makes it an attractive resource for independent developers and budget-conscious researchers.
Dukascopy: Free Bank-Grade Data with Flexible Downloads
Dukascopy—a Swiss bank—offers an unexpected but powerful source of free historical crypto data. Despite not being a dedicated crypto vendor, it tracks major cryptocurrencies and exchanges with precision.
Users can download data using customizable date ranges at no cost. However, the platform’s interface is less intuitive than modern competitors, and integration requires more manual effort.
Still, the fact that such high-quality data is completely free makes Dukascopy a compelling option for personal research or academic projects.
Finage: High-Quality UK-Based Market Data API
Finage delivers both historical and real-time financial data across global markets—including thousands of cryptocurrencies. Based in the UK, it emphasizes data accuracy and low latency.
The platform guarantees 100% price accuracy and maintains high uptime standards. However, its historical depth is limited to around eight years, which may not suffice for long-term macro analysis.
Primarily targeting enterprise clients, Finage’s pricing model reflects its professional positioning—less accessible for individual investors but well-suited for fintech companies and institutional teams.
Algoseek: Massive Data Volume with Full Customization
Algoseek boasts over 3,000 terabytes of financial data, including comprehensive crypto datasets. It supports multiple API integrations and allows deep customization of requested data fields.
Committed to transparency, Algoseek avoids third-party sources entirely—collecting and verifying all data in-house. This policy enhances trustworthiness but comes at a premium cost.
Like Finage, Algoseek is better suited for institutional use due to pricing structure and technical requirements.
