I will fix fastapi bugs and python rest API errors


About this gig
Is a FastAPI request failing or returning the wrong result? Start with one reproducible issue and a clear check that proves the repair.
I work with Python, FastAPI, validation and error handling. My experience includes deployed FastAPI apps and paid API/webhook repairs in a client platform.
Basic: fix 1 reproducible endpoint/module defect, with a regression check and explanation. Standard is for a NEW integration: 1 documented REST provider, up to 2 endpoints. Premium is for a NEW webhook receiver: 1 provider, 2 event types, signatures, SQLite duplicate checks and bounded retries. All include changed source and setup notes.
Every tier includes deployment, HTTPS and six months hosting for the delivered compatible standalone API, not an entire existing platform. Agree capacity first. Provider fees and new features are separate. Renew through Fiverr or hand over before expiry; no automatic charge.
Send sanitized logs, reproduction steps and expected behavior for a free feasibility check. Unclear legacy faults need inspection before a fixed quote. No full rewrites, security audits, payment-flow changes or undocumented APIs.

Are Node.js repairs included?
This listing is for Python. Other stacks require inspection and a separate quote.
What is included in handover?
Changed source, checks and setup notes, plus six months hosting from launch for the delivered standalone API, with HTTPS and deployment. An entire existing platform is excluded. Agree capacity first. Provider fees and maintenance are separate; renewal or handover before expiry, no automatic charge.
What should I share initially?
Sanitized errors, runtime versions, reproduction steps and safe relevant code. Keep credentials out of public screenshots.
