API return platform keywords instead of content keywords for youtube

[Sourabh2001-dec]

When we make an iframely api call for the first time for any youtube video, the api returns valid keywords as per the content present on youtube page.
After that the susequent calls, the api no more returns content specific keywords but it returns youtube platform keywords
for ex.

Here video, sharing, camera phone, video phone, free, upload
Can Someone help with the issue?
