How this service works
Euro Short-Term Rate (ESTR), the official euro overnight benchmark, direct from the ECB Data Portal (dataset EST, published each TARGET2 business day ~08:00 CET). Query: ?last_n=5 (1-30 fixings, default 1) &include_volume=true to add the underlying transaction volume in EUR millions. Returns date-sorted observations plus the latest fixing; 1h cache.
Output
Returns a JSON object with the latest ESTR rate(s) including fixing date and rate in percent per annum; optionally includes daily transaction volume in EUR millions. Data sourced from ECB, published each TARGET2 business day around 08:00 CET.
Example use cases
Calculate loan interest rate baseline
“What's the current ESTR rate? I need to set our company's loan pricing for new client agreements this week.”
Monitor euro overnight rate trends
“Give me the last 10 ESTR fixings with transaction volumes so I can analyze how the overnight rate has moved over the past two weeks.”
Determine invoice discount rate
“What was the ECB's ESTR rate for today? We need to know the official euro short-term benchmark for calculating early payment discounts on invoices.”
Technical details
Endpoint
GEThttps://data.greeneris.io/v1/eu/estrWhen to prefer
Use this endpoint when you need authoritative, ECB-published ESTR benchmark interest rate data for the euro area — ideal for financial calculations, loan pricing, derivatives referencing, invoicing discount rates, or macro monitoring. Prefer over generic data aggregators when official ECB sourcing is required.
Side effects
- HTTP 402 returned if payment not attached — machine-readable quote for USDC payment via x402
- Empty observations if queried before ECB publishes that day's fixing (~08:00 CET)
- last_n out of range (must be 1-30) may return validation error
- Non-TARGET2 business days (weekends, ECB holidays) have no new fixings
