Currency Exchange Rate Tracker — Real-Time & Historical FX

What does Currency Exchange Tracker do?

Currency Exchange Rate Tracker is an Apify Actor that fetches real-time and historical forex exchange rates for 170+ currencies — including all major fiat currencies, leading cryptocurrencies, and exotic pairs. Powered by the Fawaz Ahmed Currency API, a free CDN-backed dataset updated daily, this forex rates API requires no API key, no account, and no rate-limit workarounds. It supports three modes: a latest snapshot of any base currency, a historical date-range fetch (up to 30 days of daily rates), and a multi-base comparison for side-by-side currency analysis — all in a single Actor run.

Why use Currency Exchange Tracker?

As a zero-config real-time FX data source covering 170+ pairs, this Actor removes the usual friction of currency data pipelines. Key business use cases:

• E-commerce localization — display product prices in your customer's local currency. Pull the latest USD → EUR, GBP, JPY, KRW rates on demand without paying for a premium FX API subscription.
• Portfolio valuation — convert multi-currency holdings into a single base currency daily. Use the converted_amount field directly in your P&L calculation.
• Travel and budget apps — build trip cost calculators with daily-updated rates for all destination currencies, with automatic CDN failover for reliability.
• Historical FX research — download up to 30 days of daily rates per run for backtesting, regression analysis, or regulatory reporting. Chain multiple runs for longer date ranges.
• Multi-currency comparison — use comparison mode to benchmark how EUR, GBP, JPY, CNY, and KRW each perform against USD in a single structured output.

FAQ

Does this Actor require an API key or account registration? No. The Fawaz Ahmed Currency API is free, MIT-licensed, and CDN-hosted. No sign-up, no key, no rate limits. The Actor uses automatic CDN failover (jsDelivr → Cloudflare Pages) for reliability.

How current is the exchange rate data? Rates are updated daily, typically by early UTC morning. For truly real-time tick data (sub-minute updates), you would need a paid FX data provider. For daily operations, reporting, and analytics, this source is sufficient.

Can I fetch more than 30 days of historical data? The historical mode supports up to 30 days per run. To fetch longer date ranges, schedule multiple sequential runs with non-overlapping dateFrom/dateTo windows, then merge the datasets downstream.
