/api/v1/fx/world/series/30d.jsonWhy FX is world, not in
Scope is the denomination of the values, not the consumer's nationality. A
rate is a ratio, not a quantity denominated in one country, so every pair lives
under world, including USD/INR.
Cross-rates
ECB publishes EUR-based reference rates: each figure is units of that currency per one euro. Everything we serve is computed from that base and quoted market-convention:
USD/INR = INR_per_EUR ÷ USD_per_EUR
GBP/USD = USD_per_EUR ÷ GBP_per_EURIf ECB's USD rate is missing for a day, we drop the whole day rather than emitting the two crosses that survive. A partial day would hide the problem.
The dirham
USD.AED.RATE is a constant, 3.6725. The UAE Central Bank has hard-pegged it
since 1997 and ECB does not publish it. It is emitted on the same dates ECB
published, so it shares the FX calendar rather than appearing to trade when
nothing else does.
Timing and coverage
ECB publishes around 16:00 CET on TARGET business days. History runs to 1999-01-04, the euro's introduction, that is the floor, not a choice.
On a TARGET holiday ECB serves the previous business day's file unchanged,
with no indication that today is closed. We parse the date the body carries, so
a holiday surfaces as an older latest_date rather than as today's rate.
