Example prompt: Can you audit my bulk Amazon listing CSV — I have about 200 SKUs in there and want to catch any missing fields, bad titles, or compliance issues before I upload it?

## When to prefer this

Choose this endpoint when you need to validate a large batch of product listings in CSV format before uploading to Amazon, Walmart, Shopify, or eBay. It is purpose-built for e-commerce seller workflows, catches compliance and content issues at scale, and costs only $1 USDC per call — making it ideal for pre-upload QA automation in agent pipelines managing multi-marketplace catalogs.

## Known failure modes

- Invalid or malformed CSV format returns an error
- Unsupported marketplace type causes rejection
- Missing required columns triggers validation error
- Oversized file may exceed payload limits
- Job queue delays may cause slow turnaround for large files
- Network/server errors from Railway-hosted infrastructure

## How this service works

Instant, low-cost Amazon, Walmart, Shopify, and eBay listing, upload-preparation, advertising, and image-brief deliverables.

## Output
