Technical details
Endpoint
GEThttps://agents.crowdspark.me/v1/fx/rates?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official ECB reference rates (not live market mid-rates) for compliance, invoicing, or accounting purposes, or when you need reliable historical rates by specific date. Prefer this over real-time forex APIs when regulatory or auditable rate sourcing from a central bank is required. Ideal for travel budgeting, multi-currency invoicing, and financial reconciliation workflows.
Side effects
- Invalid currency code returns an error or empty rates object
- Date outside ECB historical coverage (pre-1999) returns an error
- Malformed date format causes a 400 or validation error
- Unsupported or misspelled symbol codes silently omitted or error
- Weekends and ECB holidays may return the last available business day rate rather than the exact date
