Why is the result of a request through Aiohttp incorrect, but everything works through request?

Question

Python

import requests

burp0_url = "https://m.avito.ru/api/11/items?key=1&priceMin=1&priceMax=9999999&owner[]=private&sort=date&query=iphone&page=1&display=list&limit=30"
burp0_headers = {
    "User-Agent": "Mozilla/5.0 (Linux; Android 11; SAMSUNG SM-G973U) AppleWebKit/537.36 (KHTML, like Gecko) SamsungBrowser/14.2 Chrome/87.0.4280.141 Mobile Safari/537.36",
    "Accept": "application/json, text/plain, */*", "Accept-Language": "ru-RU,ru;q=0.8,en-US;q=0.5,en;q=0.3",
    "Accept-Encoding": "gzip, deflate", "Content-Type": "application/json;charset=utf-8", "Dnt": "1",
    "Sec-Fetch-Dest": "empty", "Sec-Fetch-Mode": "cors", "Sec-Fetch-Site": "same-origin", "Te": "trailers"}
r = requests.get(burp0_url, headers=burp0_headers).json()
print(r)

Gives me

{'error': {'code': 403, 'message': 'Неизвестный ключ'}}

what is the correct result

url = "https://m.avito.ru/api/11/items?key=1&priceMin=1&priceMax=9999999&owner[]=private&sort=date&query=iphone&page=1&display=list&limit=30"
    headers = {
        "User-Agent": "Mozilla/5.0 (Linux; Android 11; SAMSUNG SM-G973U) AppleWebKit/537.36 (KHTML, like Gecko) SamsungBrowser/14.2 Chrome/87.0.4280.141 Mobile Safari/537.36",
        "Accept": "application/json, text/plain, */*", "Accept-Language": "ru-RU,ru;q=0.8,en-US;q=0.5,en;q=0.3",
        "Accept-Encoding": "gzip, deflate", "Content-Type": "application/json;charset=utf-8", "Dnt": "1",
        "Sec-Fetch-Dest": "empty", "Sec-Fetch-Mode": "cors", "Sec-Fetch-Site": "same-origin", "Te": "trailers"}
    async with aiohttp.ClientSession() as cs:
        async with cs.get(url, headers=headers) as req:
            items = await req.json()
            print(items)

Gives me

{'code': 403, 'error': {'message': 'Доступ с вашего IP-адреса временно ограничен', 'link': 'ru.avito://1/info/ipblock/show'}}

although this is not the case, it works through Request, but not through Aiohttp, I can’t understand why, everything is exactly the same as in requests, but it doesn’t work
