Z.ai Usage Helper tekijä nniicckk

https://github.com/nniicckk6/zai-extention


A small browser extension that fills in data the z.ai GLM Coding Plan usage
page fetches but doesn't render — most notably the reset time for the
5-hour quota (and a live countdown), plus a subscription summary block.

Works on Chrome, Edge, and Firefox. No background script, no telemetry, no
popup. Runs entirely as a content script on the one page it's needed on.


| Where | What |
| --- | --- |
| 5 Hours Quota card | Reset Time: YYYY-MM-DD HH:MM (in Xh Ym) — was missing entirely |
| Below the cards | Subscription block: plan, price, next renewal (with auto-renew badge), validity range |

The page already requests this data from /api/monitor/usage/quota/limit and
/api/biz/subscription/list; the extension just makes the same authenticated
calls (it reads the token from localStorage) and renders the parts the
frontend leaves on the floor.
