When to use Python
Python is the best starting point for recurring research jobs, catalog QA scripts, pricing monitors and internal data pipelines. It works well when you want scheduled jobs, retries, export downloads and warehouse imports.
The quickstart keeps the workflow explicit: create the job, poll status, then download an export. That pattern is easier to debug than hiding the job lifecycle behind a black-box scraper function.
Production notes
Keep the API key in an environment variable, set request timeouts and store the job ID before polling. If a job is long-running, resume polling by job ID rather than creating a duplicate job.
For large ASIN lists, batch the inputs by research purpose or category. Smaller labeled jobs are easier for analysts to inspect in the dashboard and easier for engineers to compare over time.
Data handling
Use JSONL when every row should be processed independently. Use CSV when the output feeds a spreadsheet or BI import. Use XLSX when the end user expects a workbook and does not want to format columns manually.
The normalized product_id and product_url fields should be kept in downstream tables because they make deduplication and source attribution much easier.
Production checklist
Start with one small input and compare the delivered fields with the report, catalog or pipeline you actually need.
Keep the job ID, source URL, mode and run date with downstream exports so operators and developers can audit the same result.
