OpenRouter | Top up Credits | + Bonus

[OpenRouter] is the largest centralized API gateway for large language models (LLMs). This platform allows users to access hundreds of AI models (such as those from OpenAI, Anthropic, Google, etc.) through a single API, helping to avoid vendor lock-in and making it easy to switch between models.
Key Features

* Access to hundreds of AI models: Supports most of today's popular AI models with just one account and one API key.
* OpenAI API compatibility: OpenRouter's API is designed to be compatible with OpenAI, making it easy to integrate into existing applications or software without much reconfiguration.
* Smart automatic switching (Fallback & Routing): The system can automatically switch to another model when the primary model fails or is overloaded, while also finding the most cost-optimal models for your needs.
* Rich library of free models: Provides the `openrouter/free` feature, allowing your application to automatically route to community-provided free AI models for basic tasks.
* Pricing transparency: Flexible token-based pricing for each specific model. Users can compare prices and response speeds of dozens of models right on the company's leaderboard.

Why use OpenRouter?
* Convenience: No need to register accounts and set up payments separately for each AI provider (OpenAI, Anthropic, Google...).
* Flexibility: Easily experiment and compare which model (Claude, Gemini, GPT, etc.) is most suitable for your project.
* Cost savings: You can combine the use of multiple free models or low-cost models for simple tasks, optimizing your budget.
