Hello again ChristMedia, Below you can see the response from RapiAPI support. > "I thin the reason why he is seeing 202% usage for your API, is down to the fact that he downgraded from Ultra to Pro.

If you need further clarification please contact them directly using this contact form https://rapidapi.com/company/contact-us/ Let me know if you need anything else
