I will integrate an ai chatbot or llm API in your node js app

Add a practical AI feature to your existing Node.js app with a clearly scoped LLM integration.

I work with Node.js, Express, OpenRouter, prompt design and evaluation. My experience includes conversational features, content workflows and retrieval-augmented generation.

The starter package integrates ONE server-side endpoint with ONE LLM provider and ONE agreed prompt flow, such as a chatbot reply, summarisation or structured content response. It includes input validation, basic error handling and server-side environment-variable configuration.

You receive source changes, a sample environment template without secrets, request examples and verification notes using the agreed sample inputs.

Provider usage fees, chat UI, conversation storage, RAG knowledge bases, agents with external tools and production scaling require separate scope. No AI accuracy or business outcome is guaranteed.

Message me on Fiverr with your current backend, provider preference and expected input/output. I will confirm feasibility and scope before you order.
