Price Conversion v1 (deprecated)

Convert an amount of one cryptocurrency or fiat currency into one or more different currencies utilizing the latest market rate for each currency. You may optionally pass a historical timestamp as `time` to convert values based on historical rates (as your API plan supports). Technical Notes - Latest market rate conversions are accurate to 1 minute of specificity. Historical conversions are accurate to 1 minute of specificity outside of non-USD fiat conversions which have 5 minute specificity. - You may reference a current list of all supported cryptocurrencies via the cryptocurrency/map endpoint. This endpoint also returns the supported date ranges for historical conversions via the `first_historical_data` and `last_historical_data` properties. - Conversions are supported in 93 different fiat currencies and 4 precious metals as outlined here. Historical fiat conversions are supported as far back as 2013-04-28. - A `last_updated` timestamp is included for both your source currency and each conversion currency. This is the timestamp of the closest market rate record referenced for each currency during the conversion. This endpoint is available on the following API plans: - Basic (Latest market price conversions) - Hobbyist (Latest market price conversions + 1 month historical) - Startup (Latest market price conversions + 1 month historical) - Standard (Latest market price conversions + 3 months historical) - Professional (Latest market price conversions + 12 months historical) - Enterprise (Latest market price conversions + up to 6 years historical) Cache / Update frequency: Every 60 seconds for the lastest cryptocurrency and fiat currency rates. Plan credit use: 1 call credit per call and 1 call credit per `convert` option beyond the first.
