✨ Features

  • Instant validation — every key is checked against the real provider API, not a regex.
  • Rate-limit & balance detection — tells apart a bad key from a good key with no quota, and shows exactly when the limit resets: LIMIT — 17:20 or LIMIT — 07.11 15:00.
  • Bulk check — paste 50+ keys at once, get results in seconds.
  • Smart sorting — broken keys float to the top so you spot problems first.
  • Click to copy — click a masked key to copy it; hover to reveal the full value.
  • Stats bar — 12 OK | 3 LIMIT | 2 INVALID (17 total) at a glance.
  • Last-check time — see when each provider was last verified.

📦 Installation

From Obsidian

Open Settings → Community plugins → Browse, search for AI API Key Checker, and install — or open it directly in the community plugin catalog. Then enable the plugin.

Manual

  1. Download main.js, manifest.json, and styles.css from the latest release.
  2. Drop them into YourVault/.obsidian/plugins/api-key-checker/: 
    YourVault/.obsidian/plugins/api-key-checker/
├── main.js
├── manifest.json
└── styles.css
  3. In Obsidian: Settings → Community plugins → Reload, then enable AI API Key Checker.

Via BRAT

Add this repository in the BRAT plugin to auto-update from releases.

🚀 Usage

  1. Click the key icon in the left ribbon (or run the command AI API Key Checker: Open panel).
  2. Hit Add key, pick a provider, paste one or more keys (one per line).
  3. Read the results — grouped by provider, worst status first.

🎯 Status legend

Status Meaning
OK 🟢 Key is valid and working
LIMIT 🟡 Key works but is rate-limited or out of credits (shows reset time)
INVALID 🔴 Key rejected — check for typos or expiry
ERROR 🟠 Network issue or the provider is down

🔒 Privacy

Your keys never leave your machine except to reach the provider you are validating. There is no telemetry, no analytics, and no third-party server in between. Keys are stored locally in .obsidian/plugins/api-key-checker/data.json — treat that file as a secret and never commit it. The click-to-copy feature writes the selected key to your system clipboard only when you click it; the plugin never reads clipboard content.

🛠️ Development

npm install       # install dev dependencies
npm run dev       # watch-mode build (esbuild)
npm run build     # type-check + minified production bundle -> main.js
npm run lint      # ESLint (typescript-eslint + eslint-plugin-obsidianmd)

Source lives in src/ (main.ts = UI/plugin lifecycle, checker.ts = validation engine). Obsidian only loads the bundled main.js, so rebuild after every change. Adding a provider is a five-step change — see CLAUDE.md.
