LangChain - MESHROUTER

Any framework that supports an OpenAI-compatible base URL can target MESH.

import { ChatOpenAI } from '@langchain/openai';

const model = new ChatOpenAI({
  apiKey: process.env.MESH_API_KEY,
  configuration: { baseURL: 'https://api.meshrouter.app/v1' },
  model: 'auto',
});

Keep fallback chains, tool definitions, and structured-output schemas in the request body where the framework allows custom OpenAI fields.
