Visitors ask

What exchange rate sources does CurrencyBeacon use?

CurrencyBeacon extracts rates from free publicly available data sources and complements them with commercially available data from leading forex providers. The rates are sourced from 20+ central banks and institutions including the Reserve Bank of Australia, European Central Bank, Bank of Canada, and Swiss National Bank. The company states its rates are comparable to what you get from SIX and Morningstar.

How far back do historical exchange rates go?

End-of-day rates are available historically for all days going back to January 1, 1996.

Can I use the same API quota for both REST API calls and MCP tool calls?

Yes. REST and MCP tool calls share the same quota. Each successful MCP tool call counts as one request against the quota, and all plans include both REST API access and MCP server access on the same account.

What are the rate refresh intervals for different plans?

The Free plan offers hourly updates, Basic plan offers 15 minute updates, Startup plan offers 1 minute updates, and Professional plan offers real-time updates.

What use case is CurrencyBeacon designed for?

CurrencyBeacon is designed for production currency workflows including checkout and billing (converting at the moment of purchase), finance and reporting (closing books on official rates), product dashboards (trend lines and comparisons), and AI agents using MCP to query exchange rates.
