See [docs/API.md](./docs/API.md) for full documentation. ## CLI Usage # Install and build npm run build:cli # Validate keys node dist/cli/cli/index.js sk-proj-... node dist/cli/cli/index.js -f keys.txt cat keys.txt | node dist/cli/cli/index.js --json See [docs/CLI.md](./docs/CLI.md) for full CLI documentation. ## Supported Providers - OpenAI - Anthropic (Claude) - Google Gemini - Groq - Perplexity - HuggingFace - Replicate - Together AI - Cohere - Mistral - AWS Bedrock (detection only) - Azure OpenAI (detection only) ## Development npm install npm run dev Open [http://localhost:3000](http://localhost:3000) ## Build npm run build Static files will be generated in the `out` directory. ## Deploy to Cloudflare Pages ### Via Dashboard 1. Build the project: `npm run build` 2. Go to [Cloudflare Pages](https://dash.cloudflare.com/pages) 3. Create a new project 4. Upload the `out` directory ### Via Wrangler CLI npm install -g wrangler wrangler pages deploy out --project-name=checkapi Or use the deployment script: ./scripts/deploy.sh ### Via GitHub Actions Connect your GitHub repository to Cloudflare Pages. The build settings: - **Build command**: `npm run build` - **Build output directory**: `out` - **Root directory**: `/` See [docs/DEPLOYMENT.md](./docs/DEPLOYMENT.md) for detailed instructions. ## Privacy & Security - All API key validation happens in your browser - Keys are never sent to any proxy server - Keys are never logged or stored - Displayed keys are always truncated (first 8 characters only) ## SEO & LLM Visibility CheckAPI is optimized for both traditional search engines and AI-powered search (ChatGPT, Claude, Perplexity): - **Structured Data**: JSON-LD schema with FAQPage, WebApplication, and Organization markup - **LLM Optimization**: llms.txt file for direct AI crawler access - **AI Crawler Permissions**: Explicit allowances for GPTBot, Claude-Web, PerplexityBot - **Open Graph**: Dynamic social sharing images - **Sitemap & Robots**: Optimized for crawl efficiency See [docs/SEO.md](./docs/SEO.md) for full documentation. ## Tech Stack - Next.js 16 (App Router) - TypeScript - Tailwind CSS - Lucide React (icons) - Static export for Cloudflare Pages ## Project Structure ├── app/ # Next.js app router pages ├── cli/ # CLI tool │ ├── index.ts # CLI entry point │ └── tsconfig.json # CLI TypeScript config ├── components/ # React components ├── docs/ # Documentation │ ├── API.md # API documentation │ ├── CLI.md # CLI documentation │ ├── DEPLOYMENT.md │ ├── RATE_LIMITING.md │ └── roadmap.md ├── functions/ # Cloudflare Pages Functions │ └── api/ │ └── check.js # API endpoint with rate limiting ├── lib/ # Utility functions │ ├── cli.ts # Node-compatible exports │ └── index.ts # Browser exports ├── public/ # Static assets ├── scripts/ # Deployment and utility scripts ├── tests/ # Test scripts └── wrangler.toml # Cloudflare configuration ## License MIT ## 🌐 Related Projects Explore more privacy-first and security tools: ### Privacy & Encryption - **[Timeseal](https://github.com/Teycir/Timeseal)** - Time-locked encryption vault with Dead Man's Switch.
