    **No authentication, no registration, no rate limit, no quota.** Every endpoint is a static file served from a CDN and answers plain `GET` requests. Cross-origin requests are permitted (`Access-Control-Allow-Origin: *`), so the data can be fetched directly from a browser.


    Each dataset publishes a full JSON index, one or more CSV tables, and — where the dataset tracks change over time — an Atom change feed. `methodology.json` states how a dataset is collected and what it does and does not claim.


    Start at the [DCAT-AP catalogue](https://i6eal.de/data/catalog/dcat.jsonld) to discover everything programmatically.


    ### Licensing


    The i6eal compilation, structure and original descriptions are licensed [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/). This is **not** a blanket licence over the data itself: underlying records remain subject to the rights and reuse terms of each named official source. Every dataset carries its own source list and rights statement — see the per-operation descriptions and `dct:rights` in the catalogue.

    Distribution URLs are treated as permanent. Payload shapes are versioned per dataset through the `schemaVersion` field in each index.'
