Summary

Chat2API offers a unified, zero-cost API gateway to leading AI models by leveraging their official web UIs. It targets developers and power users seeking to integrate diverse AI services through a single, OpenAI-compatible interface, enabling flexible access and potential cost savings.

How It Works

This project functions as a local proxy server, transforming the web UIs of various AI providers (e.g., DeepSeek, GLM, Kimi) into a standardized OpenAI-compatible REST API. It utilizes Electron for its cross-platform desktop application, React for the user interface, and Koa for the backend server, managing authentication, model mapping, and request routing.

Quick Start & Requirements

• Installation: Download pre-built binaries (DMG, EXE, AppImage, DEB) from GitHub Releases. Alternatively, build from source using Node.js 18+ and npm (git clone, npm install, npm run build).
• Prerequisites: Node.js 18+ and npm (for source builds).
• Links: GitHub Releases (implied). Official Website and Documentation links are mentioned but not provided.

Highlighted Details

• OpenAI Compatible API: Provides standard endpoints for seamless integration with existing tools.
• Multi-Provider Support: Integrates with DeepSeek, GLM, Kimi, MiniMax, Perplexity, Qwen, Z.ai, and others.
• Context Management: Intelligent conversation context handling with sliding window, token limits, and summarization strategies.
• Function Calling: Universal tool calling capability via prompt engineering.
• Model Mapping: Flexible model name mapping with wildcard support and provider/account preference.
• Dashboard Monitoring: Real-time request traffic, token usage, and success rates.
• System Tray Integration: Quick access and status monitoring from the menu bar.

Licensing & Compatibility

Licensed under GNU General Public License v3.0 (GPL-3.0). This copyleft license requires derivative works to be open-sourced under the same terms, potentially restricting integration into closed-source commercial products.

Limitations & Caveats

• macOS users may encounter a security warning ("App is damaged") requiring manual bypass via sudo xattr -rd com.apple.quarantine.
• The GPL-3.0 license's copyleft nature necessitates open-sourcing any modifications or integrations, posing compatibility challenges for proprietary software.
• Authentication relies on extracting tokens from provider web UIs, which could be brittle if provider interfaces change.
