rate_limit_exceeded while requesting stats records

Hi while trying to run the default setting of stats on the api reference Im getting a 400 code error with rate_limit_exceeded message. I dont understand why is this happening.

curl --request POST
--url 'https://dialpad.com/api/v2/stats?apikey=5555555555
--header 'accept: application/json'
--header 'content-type: application/json'
--data '
{
"days_ago_end": 30,
"days_ago_start": 1,
"export_type": "records",
"stat_type": "calls",
"timezone": "UTC"
}

Can you please help me.

Thank you
