Authentication is handled automatically using the `REQUESTY_API_KEY` environment variable. Learn more in the [Requesty documentation](https://requesty.ai/solution/llm-routing/models). ```bash REQUESTY_API_KEY=your-api-key ``` ```typescript import { Agent } from "@mastra/core/agent"; const agent = new Agent({ id: "my-agent", name: "My Agent", instructions: "You are a helpful assistant", model: "requesty/claude-fable-5" }); // Generate a response const response = await agent.generate("Hello!"); // Stream a response const stream = await agent.stream("Tell me a story"); for await (const chunk of stream) { console.log(chunk); } ``` > **Note:** Mastra uses the OpenAI-compatible `/chat/completions` endpoint. Some provider-specific features may not be available. Check the [Requesty documentation](https://requesty.ai/solution/llm-routing/models) for details. ## Models | Model | Context | Tools | Reasoning | Image | Audio | Video | Input $/1M | Output $/1M | |
