This project serves as a curated navigation hub for third-party API providers offering access to large language models like OpenAI, Claude, DeepSeek, and Gemini. It targets developers, researchers, and power users seeking convenient, often free or trial-based, access to these models without complex registration processes, facilitating learning, research, and non-commercial experimentation.

How It Works

The project aggregates and verifies links to various external API providers, categorizing them with descriptive tags. It acts as a directory, not a service provider, meaning it does not host APIs, generate keys, or offer proxying. The core value lies in its systematic collection and presentation of options, simplifying the discovery of platforms that offer direct API access, free tiers, or trial credits for popular LLMs.

Quick Start & Requirements

This project is a curated list, not a deployable application. To use it:

• Access: Browse the provided list of API providers.
• Requirements: Access to the internet is necessary. Some listed providers may require an international network connection for stable access. Users must independently register with and adhere to the terms of service for each third-party API provider.

Highlighted Details

• Extensive Model Support: Features providers for OpenAI (including latest models like GPT-4o), Claude (including latest models), Gemini, DeepSeek, Llama, Qwen, and other mainstream models.
• Cost-Saving Options: Highlights providers offering free tiers, significant free trial credits (≥ $5 USD equivalent), daily check-in bonuses, or discounted rates ("1 Yuan 1 Knife").
• Categorization System: Utilizes a rich tagging system (e.g., ❤️ Public Welfare, 🆓 Free, 🎁 Free Credit, 💪 Latest Claude, ✌ Latest OpenAI, 🚀 High Concurrency, ⚡ Low Latency, 🎖️ Recommended) to help users filter providers based on cost, performance, and model availability.
• Application Integration: Lists compatible applications (e.g., LobeChat, ChatGPT-Next-Web, Cherry Studio) that can leverage the aggregated APIs.

Maintenance & Community

As a curated list, direct maintenance is focused on updating provider links and status. The project welcomes contributions for adding new providers, improving tutorials, and developing validation scripts. Community interaction is primarily managed via GitHub Issues and Pull Requests.

Licensing & Compatibility

The project is presented as a "Free open-source navigation / public welfare organization project" intended strictly for technical research and learning exchange. It explicitly prohibits any illegal or non-compliant uses. It does not provide services itself, thus licensing primarily pertains to the project's code for curation and presentation, while the underlying API providers have their own terms. Commercial use is subject to the terms of the individual third-party API providers listed.

Limitations & Caveats

This project does not offer any API services, proxying, or key generation; it merely lists external providers. Users are solely responsible for vetting the reliability, security, and terms of service of each third-party platform before use. The project explicitly warns against inputting personal sensitive information into any listed website and emphasizes compliance with relevant regulations, such as China's "Interim Measures for the Management of Generative Artificial Intelligence Services." Some providers may require an international network connection.
