Possible reasons:

1 ) Notice the “403 ERROR”, which is mentioned in the API documentation:

HTTP 403 return code is used when the WAF Limit (Web Application Firewall) has been violated.

WAF limitation is mentioned in this FAQ article:

Web Application Firewall Limits:
While we do not provide exact details on our WAF rules, if you are receiving an HTTP 403 error, you have broken a rule. Most likely, it will be a result of excessive requests within a duration of 5 minutes. However, if you are sending a request that could be perceived as malicious, it could also result in a ban of a longer duration.

For Spot, check /api/v3/exchangeInfo -> RAW_REQUESTS to know the allowed number of requests over X minutes regardless of weight.

Extra: Head over to this article to learn more about the error code status process until 403 error.

2 ) Sending request with payload as body instead of full request as query-string, example:

curl -X GET 'https://api.binance.com/api/v3/depth' -d 'symbol=LTCBTC'

query-string (without error):
curl -X GET 'https://api.binance.com/api/v3/depth?symbol=LTCBTC'

You’re probably sending “excessive requests within a duration of 5 minutes.”, try to reduce and test again.
