I will integrate openai claude or gemini API into your web app


About this gig
An AI API connection is not finished when the first response appears. It also needs validation, error handling, security, and a clear user experience.
I will integrate GPT or OpenAI, Claude, or Gemini into your existing React, Next.js, Node.js, FastAPI, or Python application.
Depending on your package, I can:
design a secure server-side request flow
add structured outputs, tools, or function calling
handle timeouts, retries, rate limits, and fallbacks
connect the feature to your database and logging
build loading, success, and error states in the UI
add focused tests, deployment support, and handover notes
This Gig covers one agreed AI workflow in an existing application. It does not include training or fine-tuning a custom model. API usage fees are paid directly by you to the provider.
Please contact me on Fiverr before ordering Standard or Premium. I will review the workflow, existing code, data sensitivity, and definition of done so the package matches the real scope.

Which AI providers can you integrate?
OpenAI or GPT, Anthropic Claude, and Google Gemini are the main options. Contact me first if you need another provider or a multi-provider setup.

No. You pay the AI provider directly for usage. I will help you use server-side keys and can add reasonable limits, logging, and cost controls.
Can you add AI to an existing application?
Yes. This Gig is designed for existing React, Next.js, Node.js, FastAPI, or Python applications with one clearly defined AI workflow.
Do you fine-tune or train custom models?
Not in this Gig. It covers API integration, prompts, structured outputs, tools, data flow, reliability, tests, and deployment for an existing model.
