How this service works
Euro foreign-exchange reference rates from the European Central Bank for 30 currencies - USD, GBP, JPY, CHF, TRY, CNY, INR, BRL and more - with cross-rates derived through EUR (USD/TRY, GBP/JPY, anything against anything) and an optional daily series up to 90 business days. The response says plainly what these are: published once per business day around 16:00 CET, not a live market rate and not tradeable.
Output
A JSON object containing the computed exchange rate (or a daily series array for multi-day requests), the base and quote currencies, the publication date(s), and metadata indicating whether the result was cached and how many units were consumed. The rates are ECB reference rates published once per business day around 16:00 CET, explicitly labeled as non-tradeable official reference figures.
Example use cases
Invoice currency conversion for accounting
“I need to book a EUR/BRL exchange rate for an invoice dated 2024-12-10 — can you pull the official ECB reference rate for that day so I can record it in our accounts?”
30-day historical series for FX analysis
“Can you get me the last 30 business days of EUR/JPY official ECB rates? I want to see the daily series so I can spot the trend.”
Cross-rate lookup for reporting
“What was the GBP/CHF cross rate on 2025-01-20 according to the ECB? I need the official published figure, not a live market price.”
Technical details
Endpoint
POSThttps://agents.dexl.io/v1/tools/fx-rateWhen to prefer
Choose this endpoint when you need official, published ECB euro reference rates for compliance, accounting, invoicing, or regulatory reporting purposes — not for live tradeable rates or real-time market data. It is the right choice when you need cross-rates between any two of the 30 supported currencies (derived through EUR), or when you need a historical daily series of up to 90 business days. Prefer it over live FX feeds when auditability and an official central bank source matter more than real-time accuracy.
Side effects
- Requested date is not a business day or falls outside the 90-day window — returns an error or no data
- Unknown or unsupported currency code — returns a validation error
- Days parameter outside 2–90 range — returns a schema validation error
- Latest rate not yet published (request before ~16:00 CET) — may return previous business day's rate
- Network or upstream ECB data unavailability — service error response
