## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability friday-seller-tools-return-reason-analysis-f23e6e46 -d '<json body>'

Example prompt: Can you analyze the return reasons for my Amazon product ASIN B08XYZ1234 and tell me what's driving customers to return it so I can figure out what to fix?

## When to prefer this

Choose this endpoint when you need to systematically diagnose why customers are returning products on Amazon, Walmart, Shopify, or eBay — especially when trying to reduce return rates, improve listing accuracy, or identify product defects. It is purpose-built for e-commerce sellers needing structured return intelligence at low cost ($0.25/call), making it preferable to general-purpose analytics tools for marketplace-specific return workflows.

## Known failure modes

- Missing or invalid ASIN/SKU results in a 400 error
- Unsupported marketplace name causes validation failure
- Insufficient return data for meaningful analysis
- Payment not received causes 402 response before processing
- Job processing timeout for large return datasets

## How this service works

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

## Output

Returns a job_id and queued status immediately; once processed, delivers a structured breakdown of return reason categories, frequency analysis, root cause diagnosis, and actionable recommendations to reduce return rates for the specified marketplace product.
