About this gig
Need AI API integration or fix? I handle requestresponse with one provider.
Packages:
- Basic 1 endpoint, code + tests + notes.
- Standard Multiple endpoints, robust tests + comments.
- Premium Full feature, all endpoints, tests, checks, notes all inclusive.
Validated with React/FastAPI proof and DeepSeek/OpenAI/langchain request. Other providers need docs review.
Before ordering, send: stack, provider/model, API docs, use case/error, expected output, and run steps. No keys in chat I may need test server access (you configure), production excluded.
Not included:
- Streaming, RAG, agents, finetuning
- Multiple providers in one order (each order covers one)
- Full app, UI, auth, payments, DB migrations
- Deployment, monitoring, provider fees, output guarantees
Revisions fix agreed scope only. New providers/models/features = new order.

Built a web app with AI and got stuck? I help creators get one blocked part of an AI built or vibe coded web app working again with clear scope and verified results.
My workflow is AI assisted and hands on. I define expected behavior, reproduce the issue, inspect the project, guide and review changes, run the app, and test the affected flow. I also build scoped prototypes with Next.js, React, Python, FastAPI, and SQLite.
No technical brief is needed. Show me what happens now, what you expected, and how to reach the problem. I will confirm whether it fits a focused, testable scope.

FAQ
What counts as one endpoint unit?
One endpoint unit is one agreed AI-provider operation wired through one existing app or backend route, with a defined request and response.
Which AI providers can you integrate?
Compatible providers are included per order. Other providers require API, authentication, and scope review before ordering.
Can you repair an existing AI API integration?
Yes, when the issue is reproducible within the agreed non-stream request-response path and has clear written acceptance criteria.
What do you need from me before starting?
Send your stack, provider/model, API docs, use case or error, expected result, and sanitized run steps. Never send API keys in Fiverr chat. Buyer-configured server-side test access may be needed after ordering.
What is not included?
Streaming, RAG/vector databases, agents, tool calling, fine-tuning, multiple providers, full apps, UI redesign, auth/payments, database integration or migration, deployment/hosting, monitoring/SLA, provider fees, and output guarantees.
What does a revision cover?
A revision corrects delivery against the original written acceptance criteria. New providers, models, endpoints, features, or changed requirements need a new scope.
