openEO API 1.2 feature:

New endpoint for metadata filters (queryables): /collections/{collection_id}/queryables. Also adds a new rel type to the collection links. Open-EO/openeo-api#396

Lacking anything better, client now leverages "summaries" which is incomplete, and raises warning if there is no match

openeo-python-client/openeo/rest/datacube.py

Lines 175 to 186 in 7ebaff2

if properties:
summaries = metadata and metadata.get("summaries") or {}
undefined_properties = set(properties.keys()).difference(summaries.keys())
if undefined_properties:
warnings.warn(
f"{collection_id} property filtering with properties that are undefined "
f"in the collection metadata (summaries): {', '.join(undefined_properties)}.",
stacklevel=2,
)
arguments["properties"] = {
prop: build_child_callback(pred, parent_parameters=["value"]) for prop, pred in properties.items()
}
