คุณสามารถใช้ API นี้เพื่อดึงข้อมูลสาธารณะของผู้ใช้ instagram:
https://api.lityapp.com/instagrams/thebrainscoop?limit=2
หากคุณไม่ได้ตั้งค่าพารามิเตอร์ จำกัด การโพสต์จะถูก จำกัด ที่ 12 ตามค่าเริ่มต้น
นี้ API ถูกสร้างใน SpringBoot ด้วย HtmlUnit ตามที่คุณเห็นในโค้ด:

I'm now nearly finished high school, and just rediscovered it. I just wanted to see if anyone is still active on here, and also correct some of my past mistakes - being a child at the time, I didn't realise I had to credit artists for their work, so I'm going to try to correct that post haste. Also; the font in my bio is horrendous. Why'd I think that was a good idea? Anyway, this is a beautiful artwork of the long-tailed pangolin by @chelsealinaeve . Check her out!",
