从JSON嵌套对象中提取特定对象

Question

我只想从Get请求的以下JSON输出中提取 Name，Domain，logo 。你能告诉我如何解决这个问题吗？

此外，到目前为止，每个请求的有效负载为200。如何将请求循环到select *之类的响应结束，但是循环多个请求

我的JSON

我尝试过的事情

    import requests
    import csv
    import json
    import pandas as pd
    
    guri="https://private-anon-73f9ac5d87-testlinssmerchantapi.apiary-proxy.com/v4/publisher/12567/merchants?access_token=99999%3A1594309998%3Adf3ce9fb99997e2a53d282562d9b9d26&country=US"
    rt = requests.get(guri)
    
    df = pd.json_normalize(rt.json())
    print (df['merchants'][0]['attribute']['logo']['value'])
