I am trying to use an API on a Web weather site that limits access to no more than 10 calls per minute. Since I need to call the API 365 times, I would like to set up a batch script that calls the API once a minute. I've looked through the Web looking for how to do this, but have yet to find a way that works. Has anyone else had this need, and found a method to do this? That would save me a lot of time.

You can do it in python directly. Much easier. I assume the website is weatherunderground? This is off-topic, so you might want to contact me in private if you need.

I think it can not be implemented using only MS-DOS.You can use javascript/C# or other programe languages.

@Ruggiero Yes, you're right. WeatherUnderground now longer allows "data scraping" of their site, replacing it with an API that limits the amount of calls depending on the subscription. I would like to contact you to discuss python, with which I'm not very familiar. My e-mail address in yjhuang@whiteboxtechnologies.com

Following Amir's lead, I found this was very easy to do, i.e., just add a

choice /C X /T 60 /D X 1 > nul

to the batch script.. Worked great for me. I had wanted to post this as an answer to my own question, but was told by Unmet Hours that as a New User I had to wait for 2 days, so I decided to post it as a comment to Amir's answer, which Unmet Hours then asked if I wanted to convert to an answer :-)

To schedule in MS-DOS or the CMD shell you can use the AT command or SCHTASKS program which are available at the command line depending on your version of Windows/DOS. But these are really intended on scheduling a task that happens infrequently.

For something that needs to run as often as once per minute, you should probably use something that just causes a delay for that long. The windows CMD shell/MS-DOS does not really have a SLEEP command built (it was available in an old Microsoft resource kit) so instead I have used the PING trick described on the following page:

It is a hack but it works.

Actually the AT command was the first thing I found on the Web, but when I tried it it just got me an "Access denied" slap on the face. I also tried PAUSE with a number but that didn't work either (never thought of using SLEEP), which was when I decided to post this question in lieu of further experimentation. BTW, in the CHOICE command that did work for me (see my earlier answer) the number after the T is the number of seconds to pause. For details, see 4th post in Amir's link
