Issues querying against Catalog API

One more related question if anyone may know. I’d like to query multiple collections in one requests, but get a 400 doing that.

Using something like this in the post data: collections: [sentinel-1-grd, sentinel-2-l1c, sentinel-2-l2a]

I’ve queried other providers STAC api and was able to exclude the collections field all together and get everything back. Doesn’t seem to be the case here.

I just tried adding a random bbox in the query and got a 200. I don’t see any documentation on required fields. Hopefully that helps someone else.

Hi Eric,

To answer your first question, it seems that you didn’t include an area of interest in your request. You can build a Catalog API request using python requests with the following:

import requests

url = "https://services.sentinel-hub.com/api/v1/catalog/1.0.0/search"
headers = {
  "Content-Type": "application/json",
  "Authorization": "Bearer {token}"
}
data = {
  "collections": [
    "sentinel-1-grd"
  ],
  "datetime": "2023-01-01T00:00:00Z/2023-01-07T23:59:59Z",
  "intersects": {
    "type": "Polygon",
    "coordinates": [
      [
        [
          12.487366,
          41.907898
        ],
        [
          12.541001,
          41.893716
        ],
        [
          12.511216,
          41.88247
        ],
        [
          12.498519,
          41.891033
        ],
        [
          12.468492,
          41.890522
        ],
        [
          12.482218,
          41.906238
        ],
        [
          12.487366,
          41.907898
        ]
      ]
    ]
  },
  "limit": 10
}

response = requests.post(url, headers=headers, json=data

My example that I built in Request Builder (a great app to get familiar with the APIs) will return one result with the parameters I provided.

To answer your second question, you are limited to searching for a single data collection when using Catalog API.
