I will integrate chatgpt or claude api into your app or workflow
Cesar Toral
About this gig
I connect AI models to the thing you already have.
The hard part isn't calling the API. It's what happens when the model returns something unexpected, or the provider goes down at 2am, or a runaway loop quietly spends your monthly budget in an afternoon.
WHAT YOU GET
- Structured output with validation, so bad responses get caught instead of written to your database
- Retry logic with backoff for provider errors
- A fallback path when the model is unavailable, so your app doesn't go down because a provider does
- Cost controls and token limits
- Clear logging of what was sent and what came back
WHAT I BUILD WITH IT
- Classify or tag large volumes of text: support tickets, reviews, emails, documents
- Generate structured documents from raw input
- Extract fields from unstructured text into clean data
- Chat interfaces over your own content
- Multi step agent workflows where one task feeds the next
Tell me what you're trying to automate and roughly what volume, and I'll tell you if AI is even the right tool. Sometimes it isn't, and I'll say so.

FAQ
Do I need my own API key?
Yes. You'll create an account with OpenAI or Anthropic and add credit. I'll walk you through it step by step. This keeps you in control of both the spending and your data.
How much will the API cost me to run?
Depends on volume and model, usually cents per request. Tell me your expected volume and I'll estimate before you order. I also build in cost controls so a bug can't drain your account overnight.
Which model should I use?
Depends on the task. Cheaper models handle classification and extraction fine; the larger ones are worth it for complex reasoning. I'll recommend based on what you're actually doing, not on what costs more.
What if the AI gives wrong answers?
That's why validation matters. I build structured output checks so malformed responses get caught rather than saved to your database. For accuracy on your specific task, we test on real samples before going live.
Can you add this to my existing app?
Usually yes. Tell me the language and framework, and share the relevant code if you can. Python is my primary language, and I work with JavaScript and TypeScript as well.
