Hello, I would like to download the quarterly SR base maps, ideally the normalized images with NIR. I am using the mosaics API to search for available imagery with:

basemap_url = (
    "https://api.planet.com/basemaps/v1/mosaics/?_page_size=2000&name__contains=SR"  
)
basemapServiceResponse = requests.get(url=basemap_url, auth=auth)

basemaps = basemapServiceResponse.raise_for_status()
if basemapServiceResponse.status_code != 204:
    basemaps = json.loads(basemapServiceResponse.text)
basemaps.get("mosaics")

In the results I only see monthly products with names matching the pattern:

ps_monthly_analytic_sr_subscription_2016_09_mosaic

Even then, I am unable to download those images. I have had success with downloading files matching this pattern:

global_quarterly_2016q1_mosaic

But these do not include NIR. 

The code I am using to place my order is:

def place_order(request, auth):
    response = requests.post(
        order_url,
        data=json.dumps(request),
        auth=auth,
        headers={"content-type": "application/json"},
    )
    print(response.json())
    order_id = response.json()n"id"]
    print(order_id)
    order_url_id = order_url + "/" + order_id
    return order_url_id

order_params = {
    "name": "Basemap order with geometry",
    "source_type": "basemaps",
    "order_type": "partial",
    "products": "
        {
            "mosaic_name": "ps_quarterly_sen2_normalized_analytic_subscription_2023-01-01_2023-04-01_mosaic",
            "geometry": geometry,
        }
    ],
    "tools": "{"merge": {}}, {"clip": {}}],
}

place_order(order_params, auth)

And I am receiving this message:

{'field': None, 'general': '{'message': 'Unable to accept order: no basemap quads were found that match order parameters'}]}

     10 print(order_id)
     11 order_url_id = order_url + "/" + order_id

KeyError: 'id'

I am new to Planet imagery and the APIs so I am wondering if I am doing something wrong or if I simply do not have access to these products. I am at a university with a E&R (Departmental or Campus Package) license. Any information would be appreciated!
