Integrate today

import { OpenAI } from "openai";

const client = new OpenAI({
baseURL: "https://ai-gateway.helicone.ai",
apiKey: process.env.HELICONE_API_KEY
});

const response = await client.chat.completions.create({
model: "claude-4.5-haiku", // Or 100+ other models - helicone.ai/models
messages: [{ role: "user", content: "Hello, world!" }],
});

Why integrate?

  • Single line integration (just change the baseUrl)
  • Observability by default - trace, monitor, and observe every LLM
  • Automatic failover (no more 429s!)
  • Always pick the cheapest provider
  • Model management, response caching, rate limits, and model routing
  • Prompt management, versioning, and playground
  • Export to Pothog for custom dashboards
  • Enterprise compliant
