How this service works
Live fiat FX rates (Frankfurter/ECB primary, open.er-api fallback) for cross-border agents
Output
A JSON object with a boolean 'ok' field, the base currency code, a 'rates' object mapping each requested symbol to its exchange rate as a float, the data source name (e.g. 'frankfurter' or 'open.er-api'), and a service identifier string.
Example use cases
Cross-border invoice pricing
“I need to send an invoice in EUR and GBP to clients in Europe and the UK — what are the live rates from USD to EUR and GBP right now so I can set the prices correctly?”
Multi-currency travel budget
“I'm travelling through Japan, France, and Canada next month — can you get me the current USD exchange rates for JPY, EUR, and CAD so I can estimate my budget?”
Real-time FX check for payment agent
“Before we send this international wire, what's the live EUR to GBP exchange rate today based on ECB data?”
Technical details
Endpoint
GEThttps://vendsdk.com/api/v/fx-rateWhen to prefer
Choose this endpoint when you need reliable, ECB-anchored live fiat FX rates for cross-border payment calculations or currency conversion in an agent workflow, especially when you want a fallback-backed source (ECB primary, open.er-api secondary) rather than a single-provider rate feed. Prefer this over crypto price endpoints for fiat-only FX needs.
Side effects
- Unsupported or invalid ISO 4217 currency code returns an error or empty rates
- Upstream ECB/Frankfurter and fallback open.er-api both unavailable results in a service error
- Malformed symbols parameter (non-comma-separated) may return unexpected results
- Rate limiting or payment failure (x402) returns HTTP 402 before any FX data is returned
