How can use X-RateLimit-Limit: 20 in CURL call to avoid the error of to many requests.
x-ratelimit-limit shows the maximum number of requests available in the current time frame. The time frame is variable. For the /userinfo endpoint, the time frame should be 1 minute, so as far as I know, x-ratelimit-limit is telling you that you could make 20 or fewer cURL calls every minute to the /userinfo endpoint.
You could also use x-ratelimit-remaining or x-ratelimit-reset to control the usage too.
I wanted to add something else: Consider requesting an
id_token instead of calling
/userinfo to get information about the user.
