How this service works
Delx Commerce currency exchange rates API for agents at $0.001 USDC. Call when you need daily ECB FX rates (EUR/USD/BRL and other published pairs) with source attribution—not a live broker quote or trade execution. Returns bounded cross-rates via x402; informational only, no trading advice.
Output
Returns a JSON object containing the ECB publication date, the base currency, and a map of quote currency codes to their reference exchange rates, along with source attribution indicating the data originates from the European Central Bank. If specific quote currencies are requested, only those pairs are returned; otherwise all ECB-published currencies for the date are included.
Example use cases
Daily FX snapshot for finance app
“Fetch today's ECB reference rates for EUR as the base and return all published currencies so I can update my app's daily FX dashboard.”
Historical rate lookup for accounting
“What was the official ECB exchange rate for EUR to USD, GBP, and CHF on January 15th? I need it for a monthly accounting reconciliation.”
Multi-currency invoice conversion
“Get the ECB reference rates from two days ago for EUR as the base, specifically for USD, CAD, and AUD — I need to convert some invoice amounts for a client report.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/fx-ratesWhen to prefer
Choose this endpoint when you need authoritative, official ECB daily reference rates for informational or accounting purposes, especially when source attribution is required. It is ideal for compliance-oriented use cases, historical lookups up to 31 days back, or when you need cross-rates derived from ECB-published EUR pairs. Do not use it when you need live intraday market rates, executable transaction quotes, or rates for currencies not published by the ECB.
Side effects
- Date outside the 31-day lookback window returns an error or empty result
- Non-ECB-published currency pair requested returns no rate for that currency
- Invalid ISO currency code format triggers a validation error
- Timeout exceeded (max 8 seconds) returns a timeout error
- ECB publication not yet available for the current day (rates typically published mid-morning CET) may return previous day's data or an error
