Vichar Developer Resources

This section is for developers building applications on top of Vichar — with our command-line tool, the MCP server, the Vercel AI SDK via our first-party provider package @llmgateway/ai-sdk-provider, and TanStack AI via the first-party @tanstack/ai-llmgateway adapter.

API entry points

OpenAPI specification — typed request, response, and error schemas
Authentication — API keys and access control
Developer dashboard — projects, keys, usage, and budgets
API versioning and deprecation policy — compatibility and retirement notices

Guides

Vichar CLI — Launch coding agents, scaffold projects from templates, generate agent configs, and manage keys, budgets, and usage from the terminal
Model Context Protocol (MCP) — Use Vichar as an MCP server from Claude Code, Cursor, and other MCP clients
Using the AI SDK — Install the provider, generate and stream text, call tools, and wire up Next.js routes
Image Generation with the AI SDK — Generate images with generateImage and stream image output through chat
Using TanStack AI — Stream chat with useChat, call tools, and surface reasoning through the first-party @tanstack/ai-llmgateway adapter

Why the AI SDK

The AI SDK gives you one TypeScript interface for text generation, streaming, tool calling, and image generation. Combined with Vichar, a single provider instance and one API key reach every model in the catalog — see the models page for what's available.

Other ways to integrate

If you're not using the AI SDK:

Use any OpenAI-compatible SDK against https://api.vichar.io/v1 — see the Quickstart
Use the Anthropic SDK against the Anthropic-compatible endpoint
Call the REST API directly — see the API reference in the sidebar
