z.ai Quota Reset Timer

Browser extension for the z.ai API subscription page.

Why

The z.ai subscription page at https://z.ai/manage-apikey/subscription shows quota usage percentages but doesn't display when the quota resets in your local timezone. You're left guessing when you can use the API again.

What it does

• Adds a reset countdown bar inside each quota card (5h quota and monthly web search quota)
• Shows the exact reset time in your local timezone with a color-coded progress bar (red = long wait, yellow = halfway, green = almost reset)
• Displays the current quota multiplier badge (peak 3x / off-peak) with local peak hours on hover
• Shows a message when the 5h quota hasn't started yet
• Auto-switches to the "Usage" tab on page load

Compatibility

Only tested on the legacy pro plan with 5-hour and monthly reset cycles. Plans with weekly resets or different quota structures have not been tested and may not display correctly.
