Formation of requests according to rate limits​

Python example​

import time
import requests
url = "https://api-connect.eos.com/api/gdw/api?api_key=<your_api_key>"
RATE_LIMIT = 10  # ten requests per minute
MINUTE_IN_SECONDS = 60
payload = {
    "type": "mt_stats",
    "params":
        {
            "bm_type": "NDVI",
            "date_start": "2020-01-01",
            "date_end": "2020-09-20",
            "geometry":
                {
                    "coordinates":
                        [[
                            [lon,lat],
                            [lon,lat],
                             .........,
                            [lon,lat]
                        ]],
                    "type": "Polygon"
                },
            "reference": "ref_20200924-00-00",
            "sensors": ["sentinel2"],
            "limit": 10
        }
}
headers = {
    'Content-Type': 'application/json'
}
for request in range(10):
    response = requests.request("POST", url, headers=headers, json=payload)
    time.sleep(MINUTE_IN_SECONDS / RATE_LIMIT)
    print(response.status_code, response.json())

Bash example​

while :
do
    curl --location --request POST 'https://api-connect.eos.com/api/gdw/api?api_key=<your_api_key>' \
    --header 'Content-Type: application/json' \

                                    .........,
                                    [lon,lat]
