answers 402

Convert one base currency to up to 30 targets in a single call — fiat (~200 currencies incl. SAR, AED, COP) and major crypto — ECB reference rates + Coinbase spot, no API key. Per target: rate, converted amount, rate date, source. The batch sibling of /currency-exchange/convert: 30 pairs for one $0.02 call instead of 30 singles.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
