I'm trying to get information out of an api. If I understand correctly, once I use the json module I should get a dictionary where I should be able to extract the information from.

But no matter what key I use I get an error

import requests


r = requests.get('https://api.mercadolibre.com/sites/MLA/search?q=gt 710  usado &sort=price_asc')
a  = r.json()

print(a['title'])

Following error no matter what keyword I use

Traceback (most recent call last):
  File "C:\Users\asdf\Desktop\la\some.py", line 8, in <module>
    a["title"]
KeyError: 'title'

CodePudding user response：

title is nested under results in your json object.

import requests

r = requests.get('https://api.mercadolibre.com/sites/MLA/search?q=gt 710  usado &sort=price_asc')
a = r.json()

for result in a['results']:
    print(result['title'])

Output
