Use cases

Exchange rates for SaaS billing

Display plan prices in local currency and keep MRR reporting in one base currency.

Example

Your pricing page shows "$29/mo" as "₹2,400/mo" to visitors in India for clarity, while you still bill and report in USD. A cached hourly rate powers the display conversion.

# Show a 29 USD plan in INR
curl "https://rate-api.com/api/v1/YOUR_KEY/convert?from=USD&to=INR&amount=29"
