Multi-Currency API: Show Prices in USD, AED, EUR and 150+ Currencies with OtpGet

Your customers do not all think in the same currency. A reseller in Dubai wants AED, one in Europe wants EUR, a developer in the US wants USD. OtpGet's API handles that for you, so you never write an exchange-rate updater of your own.

The currency parameter

Add &currency=CODE to supported requests and every amount in the reply is converted to that currency:

https://otpget.com/stubs/rental-handler.php?api_key=YOUR_API_KEY&action=getRentalPricing&currency=AED

• Codes are case-insensitive, so usd and USD both work.
• If you leave the parameter out, amounts stay in the site's base currency, exactly as before. Existing integrations do not break.
• An unsupported code returns BAD_CURRENCY.

getCurrencies: the list of supported codes

Returns every currency code you can pass. Use it to build a currency selector in your own app and validate input before calling the API.

Where it helps

• Reseller panels that show customers their balance and prices in a local currency.
• Dashboards that report spending in the finance team's reporting currency.
• Price tables for customers in many countries from one codebase.

A note about rounding

Converted amounts are display values calculated from current rates. Charges are always made in the account's base currency, so a small rounding difference between display and ledger is normal. For accounting, store the original base-currency amount.
