## 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-listing-suppression-diagnosis-ab3ec12d -d '<json body>'
```

Example prompt: My Amazon listing for ASIN B09XYZ1234 got suppressed and I have no idea why — can you run a suppression diagnosis on it and tell me exactly what's wrong and how to fix it?

## When to prefer this

Choose this endpoint when a seller needs to quickly understand why a specific product listing is suppressed on Amazon, Walmart, Shopify, or eBay and wants actionable remediation steps. It is particularly useful for AI agents automating seller account health workflows, or when a seller tool dashboard needs to surface suppression root causes at low cost ($0.25 per call) without building in-house marketplace compliance logic.

## Known failure modes

- Invalid or unrecognized listing ID / ASIN returns an error or empty diagnosis
- Unsupported marketplace platform causes a validation failure
- Payment of $0.25 USDC not confirmed results in 402 Payment Required
- Listing is not actually suppressed, so no suppression reason is found
- Rate limiting or server timeout on the Railway deployment returns a 5xx error

## 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 upon submission; the completed diagnosis report includes the identified suppression reason(s), affected listing details, and prioritized remediation steps specific to the target marketplace (Amazon, Walmart, Shopify, or eBay).
