A good bet. I update every 15 minutes and have yet to notice an issue.
The number of minutes between 6pm and noon the next day is 1080, which is close to 1000 calls/24h hours. This might be the daily limit.

Per this ChatGPT answer, the API limits are 1500 calls per day, and 30 calls per minute.

BTW, on the screenshot in the previous post, I've just noted an upcoming "Expiration date" for my API Key (10/28/2025)..
I don't recall a notice of this when signing up. This is ~6 months from when I received the key (4/25/2025).
Anyway, I've set of up a calendar reminder. It will be interesting to learn if I can renew the API Key, or need to generate a new one.

I do it every minute and haven't had any issues. There are 1440 minutes in a day, so (based on what you showed above) doing it every minute should not make it exceed the 1500 limit.

Just a thought - maybe there's a different limit for us 'freeloaders' who are not sharing data from an actual PWS.
EDIT: I just asked ChatGPT and it did not find a different usage tier for 'fake' PWS users. Here's its updated response.

I probably should have known everything has a limit but never really paid attention to it. It had been working for a couple of years with the 1 minute updates but that was without a key and of course it stopped working when they started making us have a key. I'm at 1440 per day but I'm using the same API key for both myself and dad so my count is really 2880 a day LOL. Whoopsies....guess I need to create a key for dad.
I was just about to ask if you were the only user of the API key.

Go to the map then zoom in on your area.

Pick one of those stations near you then get the Station ID then plug that into BIT along with the API Key you created.

Yes, I already have it working. I do have a PWS uploading data though too.
Did you check your WU API key usage chart? Just wondering if ChatGPT is correct about the the 1500/day daily limit?

You were correct! As soon as I hit the 1500 limit the failures began. Again, it was because I was sharing a key between two BI machines and updating every minute on both of them. I've gone back and created a unique API key for each BI machine.
I just created a WU acct, then created a PWS that I named ‘Virtual’, haha. Then I got an API key, plugged it into BIT, hit update and my BIT weather updated for the first time in months.
I wonder if the virtual PWS is even needed? I did that step first so I’m not sure if it will give you an API key without doing that step first or not. If you get an API key just by creating a WU acct, I wonder if that could be skipped? Up and working great either way.
Thanks guys.
