You will get one broken OpenAI or Claude API call fixed in your Python backend


Project details
Please message me before ordering so I can confirm your error, codebase, and package fit.
WHAT YOU GET
I will trace and fix one failing OpenAI or Claude API call in your Python backend, then leave a small, reviewable patch. You get a reproducible call path, a focused code fix, regression tests appropriate to the tier, and a plain-English root-cause note. Work is limited to one codebase, one environment, and one provider.
DONE WHEN
The agreed call path reproduces the original failure or its supplied evidence, the patch resolves the agreed issue, and the included tests pass in the agreed local or Docker workflow. I will document how to run the proof and any remaining assumptions.
NOT INCLUDED
New product features, UI work, multi-service incident response, production deployment, account/billing changes, provider-side outages, or security audits. Do not send production API keys, passwords, or secrets in plain chat; use redacted configuration and your approved secure-access method if access is needed.

HOW I WORK
We agree on the failure mode, scope, and proof of completion before I build. You receive reviewable increments, tests, clear tradeoffs, concise status updates, and handoff documentation.
Before hiring or ordering a Project Catalog package, send me an Upwork message with your current stack, what is failing or missing, and the outcome you need. I’ll confirm fit and recommend the smallest practical next step.
Steps for completing your project
After purchasing the project, send requirements so Chris can start the project.
Delivery time starts when Chris receives requirements from you.
Chris works on your project following the steps below.
Revisions may occur after the delivery date.
Confirm the failure and scope
I review the evidence and confirm the affected call path, provider, environment, and package boundary.
Reproduce the issue
I reproduce the failure or validate it from sanitized evidence and isolate the root cause.
