The problem & context

Pollstar, a live-entertainment industry publication, connecting language models with internal and external music APIs through a web app and agent.

02

Architecture

A React chat interface calls FastAPI on Azure App Service, which runs a single LangChain and LangGraph agent with memory and checkpointing. The agent reasons with GPT-5.4 and GPT-5.4 mini through Azure AI Foundry, calls tools hosted on an Azure Function App that consume the existing .NET music APIs, and uses retrieval-augmented generation over a FAISS index to read documents. Azure Cosmos DB holds conversations, agent state, and metadata, while LangSmith and Langfuse support tracing, evaluation, prompt monitoring, and cost tracking.
