I guess I’ll open this in a new thread. While exploring CAMS Charts I noticed there’s an option to see more docs about REST API for charts.

Trying to open that documenation [link](https://charts.ecmwf.int/opencharts-api/v1/swagger-ui/?package=cams_air_quality&product=europe-air-quality-forecast-pollens) leads to a page that’s stuck on loading.
