⚠️ You're about to paste a live Anthropic API key into a web page
This sends your key to a qalarc.com Cloudflare Worker, which makes
one tiny billed request to Anthropic to read your rate-limit headers.
We never store the key (not in any database, not in logs) — it's
used for that single request and discarded. The Worker is open source.
Pasting live API keys into third-party web pages is generally a bad
habit. Only do this with a key you can rotate, and ideally a low-limit one.
✅ The safe option: run Claude Pulse locally — your key
never leaves your machine. See the
project page /
GitHub.
Key stays only in your browser + the one-shot Worker request. Nothing is saved.

Claude Pulse is open source (MIT). This hosted page is a convenience demo;
the full experience — live tokens-per-minute gauge, usage-over-time graph
with rate-limit markers, and history — runs locally with zero credential
risk. ·
