What is Error 1020 and how to resolve them? – CoinGecko

Error 1020 typically refers to a "Access Denied" error generated by a web application firewall (WAF) like Cloudflare. This error occurs when the firewall rules in place block your access to CoinGecko's API. It's a security measure to protect against various online threats.

One potential solution for this issue is to check if your user agent is empty. If it is, you should set it to something else. The user agent is an HTTP header that your browser sends to identify itself to the web server. An empty user agent might trigger security measures in the firewall.

To set your user agent to something else, you can use various methods depending on your programming language or tool. For example, in Python using the requests library, you can set the user agent like this:

import requests

headers = {
    'User-Agent': 'Your User Agent Here'
}

response = requests.get('Your API URL', headers=headers)

Replace 'Your User Agent Here' with an appropriate user agent string.
