Room to test a real workload
5,000 free monthly calls give you room to build around your own traffic pattern, from a small currency converter to a recurring rate lookup. No card is required, and any supported currency can be the base. The usage table maps three monthly volumes to the lowest qualifying plan, making the next step clear as requests grow. Free permits commercial display with linked credit; paid plans need no credit.
Rates with a time and a source
All 144 currencies update about every 60 seconds on trading days, 15 minutes late on Free. Responses include source and market-session fields alongside observation timestamps, so your application can show where a value came from and when it was observed. Daily references remain identifiable as daily data. That context belongs beside the number in a customer interface, an internal report, or an agent answer that explains the rate it used.
One account for apps and agents
Every plan includes REST and MCP. Plus and Pro daily history reaches 1999 for majors; pair starts vary, combining current and dated records. A developer can start with the HTTP examples above, then use MCP for agent queries without adding another subscription. The same base and target currencies carry through the workflow, from fetching a current rate to looking up a historical observation.
When they are the better pick
currencyapi.com is a better fit for a combined fiat, crypto, and metals catalog. It has averages, fluctuation, and central-bank endpoints. End-of-day history reaches 1999, and paid plans offer hourly or 60-second updates.
