I want to add monitors in China (pi with GPS) to improve the server numbers of CN or countries around maybe? How to get the API keys?

As we’re talking about China, I’ll have to confirm. Do you have your own IP address, ie. one that is not shared with others? Having a monitor behind CGNAT might not work well for monitoring purposes, because NTP servers might have query rate limitations. ---

Having a monitor behind CGNAT might not work well for monitoring purposes, because NTP servers might have query rate limitations. I’m not sure that would be a problem in practice. I can’t speak for the pool admins, but each monitor is currently querying each server at most every 6 minutes. See for example [https://www.ntppool.org/scores/38.81.211.177/log?limit=30&monitor=9](https://www.ntppool.org/scores/38.81.211.177/log?limit=30&monitor=9) Rate limiting in ntpd defaults to limiting each client IP address to one query every 2 seconds and averaging no more often than every 8 seconds. It would take quite a few well-behaved clients sharing the same CGNAT public IP with a monitor to trip rate limiting. ---

Throw in one bad-behaving client behind the same CGNAT and you have a problem. ---

Yes, That’s own by me (for a while), since ISP will change the IPv4 address in about 2 days. IPv6 will change prefix for daily.
