Different Cloud Cover Value from sentinel-hub.com catalog search and creodias.eu query APIs

[hosam.abduljalil]

The cloud cover value returned from services.sentinel-hub.com is 0 but it is 0.185922 from CREODIAS search query for the same parameters and same result ID: S2B_MSIL2A_20240101T075239_N0510_R135_T37QED_20240101T092022

I used this end point https://services.sentinel-hub.com/api/v1/catalog/1.0.0/search
to search for open images in sentinel-2-l2a with the following body and I get 1 feature result

{
    "collections": [
        "sentinel-2-l2a"
    ],
    "datetime": "2024-01-01T00:00:00Z/2024-01-01T23:59:59Z",
    "intersects": {
        "type": "Polygon",
        "coordinates": [
            [
                [
                    39.194026,
                    21.535326
                ],
                [
                    39.194026,
                    21.49013
                ],
                [
                    39.243487,
                    21.49013
                ],
                [
                    39.243487,
                    21.535326
                ],
                [
                    39.194026,
                    21.535326
                ]
            ]
        ]
    },
    "filter": {
        "op": ">=",
        "args": [
            {
                "property": "eo:cloud_cover"
            },
            0
        ]
    },
    "filter-lang": "cql2-json"
}

The result feature cloud cover is 0

But when I use CREODIAS search query API using this endpoint: https://datahub.creodias.eu/odata/v1/Products I get 1 result but with different cloud cover value

full query:

[type or paste code here](https://datahub.creodias.eu/odata/v1/Products?$filter=((ContentDate/Start%20ge%202024-01-01T00:00:00.000Z%20and%20ContentDate/Start%20le%202024-01-01T23:59:59.999Z)%20and%20(Online%20eq%20true)%20and%20(OData.CSC.Intersects(Footprint=geography%27SRID=4326;POLYGON%20((39.211099%2021.515989,%2039.213747%2021.506454,%2039.22653%2021.506883,%2039.224226%2021.515561,%2039.211099%2021.515989))

The result cloud cover is 0.185922

What’s the reason how ever both results for the same API and time stamp and the same product ID:
S2B_MSIL2A_20240101T075239_N0510_R135_T37QED_20240101T092022
