[Python] How can I use GPT-4 API to generate structured affiliate product reviews in real time...

I’m building an automated affiliate blog platform that uses FastAPI (Python) and OpenAI’s GPT-4 API to generate complete product reviews in real time.

The idea is:

Fetch product specs via an external API (e.g. Amazon, Geizhals)

Send them to GPT-4 with prompt instructions to generate SEO-friendly reviews

Return clean HTML content including meta tags, structured headings, and a schema.org JSON-LD block

My current challenges:

Managing async API requests to both OpenAI and product APIs

Ensuring reliable and unique content structure (e.g. summary, pros/cons, CTA)

How to instruct GPT to return valid JSON (for meta + schema data) alongside readable HTML

Handling OpenAI timeouts and token limitations for long product descriptions

Embedding the full logic into a FastAPI endpoint that’s scalable and easy to monitor

Has anyone implemented something similar – ideally for affiliate or content automation use cases?

I’d especially appreciate insights from those who’ve implemented similar content automation workflows or used GPT for structured SEO content.
