simple bot that runs perspective API checks on Discord messages and adds reacts if they score high

bot.py

import discord, json, requests
from ratelimit import limits


#set up Discord client
client = discord.Client()

#rate limit decorator because Perspective API limits you to 1 query per second
@limits(calls=1, period=1)
def toxic_check(message):
    api_key = 'YOUR_KEY_HERE'
    url = ('https://commentanalyzer.googleapis.com/v1alpha1/comments:analyze' + '?key=' + api_key)
    
    #Ask Perspective to analyize for "attacks on identity." Other values such as TOXICITY can be found in their docs
    data_dict = {
        'comment': {'text': message},
        'languages': ['en'],
        'requestedAttributes': {'IDENTITY_ATTACK': {}}
    }

    response = requests.post(url=url, data=json.dumps(data_dict)) 
    response_dict = json.loads(response.content) 
    attack = response_dict["attributeScores"]["IDENTITY_ATTACK"]["summaryScore"]["value"]
    return attack

@client.event

    if message.author == client.user:

    #put the check in a try in case we hit the rate limit. Exceeding the rate limit will just drop the check and no react will get added
    try:
        if toxic_check(message.clean_content) > 0.9: #0.9 is near the max. I had it at 0.7 and people got annoyed
            await message.add_reaction("🏳️‍🌈")
