Get notified when a next.js theme is uploaded

I would like to know whether its possible to get notified everytime a “next.js”(a certain type of react.js theme) theme is uploaded onto envato marketplace.
A possible way would be to let me search envato marketplace through an API rather than physical search. My app will check the search results of “nextjs” on a regular basis to see if new products are available.
P.s Willing to pay a monthly subscription for the API access. Thanks in advance.
