EU Open Data Portal MQA Metrics Cache API

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.

Where this information came from

This is an independent, third-party profile of EU Open Data Portal MQA Metrics Cache API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
