About
Each request renders an animated GIF that counts down to a target date or timestamp. The animation contains up to 60 frames at one frame per second, looping within the current minute bucket. Identical requests in the same minute are served from an in-memory cache on warm instances.
Use optimize=balanced for a good default, optimize=speed when response time matters most,
or optimize=quality when smoother text is more important than file size.
