EU Open Data Portal MQA Metrics Cache API is one of 7 APIs that [EU Open Data Portal](https://apis.io/providers/eu-open-data-portal/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Data Quality, MQA, DCAT-AP, and Metrics. The published artifact set on APIs.io includes an OpenAPI specification, an API reference, and API documentation.

The Metadata Quality Assurance (MQA) metrics cache. Serves DCAT-AP quality scores for every catalogue, country, dataset and distribution across five dimensions — findability, accessibility, interoperability, reusability and contextuality — on a 450-point scale, with historic series, distribution reachability and SHACL violation reports. Read operations are public; admin refresh operations require an API key.
