currencystack.io is a foreign exchange rates and currency conversion API built and managed by PushBots. It is positioned as a lightweight data service for developers. It provides real-time exchange rates for 154 world currencies, returns data in JSON format, and emphasizes usability in any programming environment. The page also notes that the product is being integrated into currencylayer.com and recommends users switch there to continue using the API.
Functionally, it covers real-time exchange rates, currency conversion, and mid-market rates, making it suitable for financial apps, cross-border e-commerce, price conversion, billing systems, and data dashboards. In terms of data sources, the page says exchange rate data comes from top-tier financial data providers, commercial sources, and banks, and that its accuracy can be compared against independent sources such as Google and Yahoo Finance. The API outputs JSON, lowering integration costs. The official site also mentions that SDKs for common programming languages are being developed on GitHub, but does not list specific languages. RapidAPI integration is a practical plus, making it easier for developers to test, deploy, and manage multiple APIs in one place.
Pricing information is relatively incomplete. The page clearly offers a free API Key, with a free quota of up to 2,000 requests per month. It also mentions early adopter pricing based on update frequency and monthly query volume, but the captured content does not show specific paid plan prices. For support, the official site says its technical support team will provide the required information, but no SLA, response time, or enterprise support details were found.
Its strengths are a lightweight interface, universal JSON output, a friendly free quota, and access through the RapidAPI ecosystem. It is a good fit for developers who only need a quick way to integrate exchange rate lookup and conversion. The downsides are also clear: the product is in the process of migrating to currencylayer.com, so its long-term roadmap and availability need to be monitored. Documentation, SDK languages, paid plans, payment methods, and self-hosting capabilities all lack detailed information. It is better suited to small and mid-sized projects, prototyping, and applications without strict SLA requirements. For financial-grade production systems, teams should further verify data licensing, service levels, and the migration plan.
The captured content does not provide information on access from mainland China, ICP filing, node locations, or payment methods, so its China access status is unknown. Domestic teams that need stable usage should test connectivity to currencystack.io, RapidAPI, and currencylayer.com, and evaluate payment, compliance, and local alternative exchange rate data sources.
