Framework Integrations

Observyze provides zero-code proxy integrations for popular frameworks like LangChain, LlamaIndex, and the Vercel AI SDK. By routing through our proxy, all chains and LLM calls are automatically traced without needing a custom plugin.

LangChain Integration

The easiest way to trace LangChain is to point the base URL to the Observyze proxy.

TypeScript Example

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

const model = new ChatOpenAI({
  configuration: {
    baseURL: "https://api.observyze.com/api/v1/proxy/openai/v1",
    defaultHeaders: {
      "Authorization": "Bearer ob_your_api_key",
      "x-project-id": "proj_123"
    }
  }
});

Vercel AI SDK

Use the custom provider setup to route Vercel AI SDK traffic through Observyze.

Next.js Route Handler

import { createOpenAI } from '@ai-sdk/openai';
import { generateText } from 'ai';

const observyzeProvider = createOpenAI({
  baseURL: 'https://api.observyze.com/api/v1/proxy/openai/v1',
  headers: {
    Authorization: `Bearer ${process.env.OBSERVYZE_API_KEY}`,
    'x-project-id': process.env.OBSERVYZE_PROJECT_ID
  }
});

export async function POST(req: Request) {
  const { text } = await generateText({
    model: observyzeProvider('gpt-4o'),
    prompt: 'Write a poem about tracing',
  });
  
  return Response.json({ text });
}
