How this service works
Convert between 30+ major currencies using official European Central Bank reference rates, current or historical since 1999. Use when converting an amount between major currencies at an official reference rate, today or on a past date.
Output
Returns the converted amount, the exchange rate used, the source and target currency codes, the effective date of the rate, and the data source (ECB). Example: {from: 'USD', to: 'EUR', amount: 100, rate: 0.92, converted: 92.0, date: '2024-01-15', source: 'ECB'}.
Example use cases
Travel budget currency check
“How much would 2000 euros be worth in British pounds at today's official ECB exchange rate?”
Historical invoice reconciliation
“I need to know what the official ECB rate was for converting 5000 USD to EUR on January 10, 2020 — can you do that conversion for me?”
Cross-border payment estimation
“Convert 12500 Swiss francs to Canadian dollars using the current ECB reference rate so I can estimate the wire transfer amount.”
Technical details
Endpoint
GEThttps://toolrail.dev/fx/convert?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an official, authoritative reference rate from the European Central Bank for major currency pairs, especially for financial reporting, invoicing, or compliance contexts where ECB rates are required. Prefer this over market-rate providers when historical accuracy since 1999 matters or when an official (non-commercial) rate is explicitly needed. For Latin American currencies (ARS, CLP, BRL, MXN, COP, PEN) use the specialized Toolrail LATAM or country-specific endpoints instead.
Side effects
- Unsupported currency code returns an error — only 30+ ECB-covered major currencies are supported, not exotic or minor currencies
- Historical date before 1999 not available — ECB data only goes back to 1999
- Weekend or holiday dates may return the most recent prior business day rate
- Missing required query parameters (from, to, amount) result in a validation error
- Invalid or malformed currency code returns an error
