European Central Bank — Money Market Survey (MMS)
The Money Market Survey (MMS) dataset is published by the European Central Bank via the ECB Data Portal as the MMS dataflow, distributed through an SDMX 2.1 REST API. A single endpoint provides data in XML (SDMX-ML), CSV, and JSON formats, with series retrievable using a key path and filters such as startPeriod, endPeriod, and lastNObservations. Covering money market indicators and prices, it allows users to extract specific time series programmatically or browse and chart the same data directly on the ECB Data Portal, supporting analysis of euro area monetary conditions.Money Market Survey (MMS) — official time series from the European Central Bank Data Portal, published as the MMS dataflow over SDMX 2.1 REST. One endpoint serves XML (SDMX-ML), CSV (?format=csvdata) and JSON (?format=jsondata); extract exactly the series you need with a key path and startPeriod / endPeriod / lastNObservations filters. Browse and chart the same series on the ECB Data Portal.
