openrouter-typescript-sdk

The openrouter-typescript-sdk skill provides a structured reference for integrating applications with OpenRouter’s unified AI API through the TypeScript SDK. It helps developers access a large catalog of AI models using a single, type-safe interface and the callModel pattern. The skill focuses on setup, authentication, and model interaction workflows, enabling developers to build AI-powered applications without managing separate integrations for individual model providers. By consolidating model access behind a consistent SDK, it simplifies application development and reduces integration complexity.

The skill covers installation and client initialization, API key authentication, OAuth PKCE authentication for user-facing applications, and API key management capabilities. Documented features include creating and configuring an SDK client, retrieving metadata for the current API key, listing and managing API keys programmatically, generating OAuth authorization codes, redirecting users through the authorization flow, and exchanging authorization credentials for API access. The SDK is described as supporting text generation, tool usage, streaming, and multi-turn conversations through the callModel pattern.

This skill is intended for TypeScript developers, application engineers, and AI agent builders who want to integrate multiple AI models through a single API. It is suitable for server-side applications that use API keys as well as user-facing applications that require OAuth-based authorization. Common use cases include building AI assistants, conversational applications, agent workflows, and developer tools that need access to a broad range of AI models while maintaining a consistent integration experience.
