Convert Currency to Multiple Currencies

About Convert Currency to Multiple Currencies

Currency Conversion is an API hosted on ApyHub that converts a single source currency into multiple target currencies in one request. The client sends a source currency code and an array of target currency codes, with an optional date parameter (in YYYY-MM-DD format) to retrieve historical rates; if the date is omitted, the API defaults to the current day's rates.

The API exposes one POST endpoint and returns a flat JSON object where each field is a source-to-target currency pair, such as usd_eur or usd_gbp, mapped to its decimal exchange rate. This format is intended for use in pricing workflows, checkout logic, reporting jobs, and internal finance tools that need to compare or normalize amounts across several currencies at once, without requiring additional parsing of the response.

Access requires an API key (apy-token) passed as a request header. The service documents standard error responses for missing or malformed requests (400), unauthorized or missing API keys (401), rate limiting (429), and upstream unavailability (503). The listing shows version 1.0.0 and is marked as verified and listed on ApyHub.
