How this service works
How do you convert between fiat currencies? Returns the daily ECB reference rate between two 3-letter codes (CHF, EUR, USD…), not a live market rate ($0.002 per call).
Output
A JSON object containing the base currency code, quote currency code, the numeric exchange rate (e.g. 1.07), the date of the rate, and the data source (ECB reference rate via Frankfurter).
Example use cases
Invoice conversion for international billing
“I need to invoice a client in euros but my base currency is Swiss francs — what's the current CHF to EUR exchange rate so I can calculate the correct amount?”
Travel budget planning in foreign currency
“I'm heading to Japan next week — what's today's exchange rate from USD to JPY so I can figure out how much cash to bring?”
Daily forex rate snapshot for reporting
“Pull the current EUR to GBP exchange rate from the ECB reference data — I need it for today's financial report.”
Technical details
Endpoint
GEThttps://api.api-agent-ia.ch/taux-de-change?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need official ECB reference exchange rates for fiat currency pairs, particularly for compliance, invoicing, or financial reporting purposes. It is ideal for lightweight, per-query lookups rather than bulk historical data. Use over generic FX APIs when ECB provenance and low cost ($0.002 per call) matter.
Side effects
- Unsupported or invalid currency codes return an error response
- Rate may not reflect real-time market prices — ECB reference rates are typically published once per business day
- Network or upstream Frankfurter API unavailability causes request failure
- Missing required query parameters (base or quote) result in a validation error
