take a deep investigation, there are many issues for the usps integration

for example:

• auth is not working because client id and secret is not passed to login https://github.com/karrioapi/karrio/blob/main/modules/connectors/usps/karrio/providers/usps/utils.py#L50

• USPS API document has been changed ,all the proxy apis are changed, USPS add a prefix to that. get rate API, in the code we have url=f"{self.settings.server_url}/v3/total-rates/search", but the actually API has been changed to https://api.usps.com/**prices**/v3/total-rates/search

• some API auth Bearer token + payment auth token, X-Payment-Authorization-Token
