Validation of Pinterest Access token

When I try to Validate my access token of Pinterest, Postman shows status 429 “too many requests”. I am sure I imported the curl command right.

The Pinterest API limits the number of requests to 10 per hour.
You’ll have to wait for another hour to send requests again.
Alternatively if you want you can create another account and to through all the process again.

Thanks.I’ll try later then.
