The Telegram-Bot result:

Telegram-bot gives the only correct answer, the result given by api is completely wrong.

[soruly]

Maybe your gif sent via Telegram bot is different from the one on imgur.
I tried sending your image url to the telegram bot, it gives the same (wrong) result as the API.

I tried again using your screencap (as a still image) and it's giving correct result.
Note that when sending GIFs, the search engine will only use the first frame of GIF for searching. Different frames from the same GIF file may return different results.
