Notes

  • The current API rate limit is 100/1 calls/minute per client's ip address.

  • All generated thumbnails will be host CloudFlare CDN and serve over https, and without any watermarks.

  • Internally I use Wappalyzer for analyzing technologies of websites.

  • Currently for accessing the APIs no need any keys.

  • The thumbnailing handles all modern websites.

  • Using headless chrome for capturing screenshots.
