Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-ebay-seller-standards-defect-projection-0bfcec33 -d '<json body>'
```

Example prompt: Based on my recent eBay transaction history, project my seller standards defect rate for the upcoming evaluation period and tell me if I'm at risk of dropping below Top Rated or Above Standard status.

## When to prefer this

Use this endpoint when an eBay seller needs a forward-looking computation of their defect rate and standards tier risk ahead of an official eBay evaluation period, rather than simply reading current eBay dashboard metrics. Ideal for proactive account management and scenario planning after high-volume sales periods.

## Known failure modes

- Missing or malformed seller account data returns a 400 validation error
- Insufficient transaction history to compute a meaningful projection
- Payment not received results in 402 Payment Required before processing
- Service unavailable on Railway deployment returns 503
- Job may remain queued if backend is under load, requiring polling

## 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 indicating the projection has been submitted for async processing; the agent can poll or await a callback with the computed defect rate projection, projected seller standards tier, and risk indicators.
