Langfuse

Prompt and generation observability on TheRouter.ai traffic

Langfuse's OpenAI wrapper can ingest TheRouter.ai calls with minimal changes, making it easy to keep historical trace continuity during migration.

Overview

This page mirrors the OpenRouter workflow and adapts it for TheRouter.ai. Use TheRouter.ai as your OpenAI-compatible endpoint and keep model IDs in `provider/model` format.

Installation

Install the required SDKs and keep your TheRouter.ai key in environment variables.

install.sh

pip install langfuse openai

Configuration

Set TheRouter.ai base URL overrides and pass your API key. Add attribution headers when your app should appear in rankings.

TypeScript

const openai = new OpenAI({ baseURL: "https://api.therouter.ai/v1", apiKey: process.env.THEROUTER_API_KEY });

Caveats

Integration note

Be deliberate about prompt capture in traces. For sensitive workloads, scrub user identifiers and secrets before sending to observability backends.

For production rollouts, pin SDK versions and validate model compatibility in staging before broad rollout.
