open-elevation api for python

can we use open-elevation with python? I tried to get the API using request and didn't work

#overpass api url
elevation_request = "https://api.open-elevation.com/api/v1/lookup\?locations\=10,10\|20,20\|41.161758,-8.583933"
elevation = requests.get(elevation_request)
data_json = elevation.json()

how can we integrate this API with python?

I am the author of https://open-elevation.com.

The service should be working much more reliably now.

Sadly, the service is widely used for free, but there is very little in the way of donations, so I have been unable to upgrade it properly to handle the load. A migration in the coming month (with more money coming out of my pocket each month) has eased this situation, but I can't tell you how long it will last.

The endpoints are valid, but they are many times slow or sometimes unresponsive. The code below is an adaptation of this answer to deal with response status codes and timeout:

from requests import get
from pandas import json_normalize

def get_elevation(lat = None, long = None):
    '''
        script for returning elevation in m from lat, long
    '''
    if lat is None or long is None: return None
    
    query = ('https://api.open-elevation.com/api/v1/lookup'
             f'?locations={_lat},{_long}')
    
    # Request with a timeout for slow responses
    r = get(query, timeout = 20)

    # Only get the json response in case of 200 or 201
    if r.status_code == 200 or r.status_code == 201:
        elevation = json_normalize(r.json(), 'results')['elevation'].values[0]
    else: 
        elevation = None
    return elevation
