TypeError: list indices must be integers or slices, not str API, Json in Python

I am trying to get data from API but facing an error. I need block height from this API.

import requests
import json


fetch_json_net = requests.get('https://api.minaexplorer.com/blocks?limit=1')
blk_height_net = fetch_json_net.json()["blocks"]["blockHeight"]
print(blk_height_net)

>Solution :

First of all, I checked what fetch_json_net.json() returns:

{'blocks': [{'blockHeight': 115919, 'canonical': True, ...

It means blk_height_net["blocks"] has a list value, not a dictionary value.

Therefore, you can get the blockHeight value, as follows:

import requests
import json

fetch_json_net = requests.get('https://api.minaexplorer.com/blocks?limit=1')
blk_height_net = fetch_json_net.json()["blocks"][0]["blockHeight"]
print(blk_height_net)
# 115919
