## 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-inventory-restock-plan-0694834b -d '<json body>'
```

Example prompt: Can you generate a restock plan for my Amazon and Shopify inventory? I want to know which SKUs to reorder, how many units, and when based on my current stock levels and sales velocity.

## When to prefer this

Choose this endpoint when you need actionable, marketplace-specific inventory replenishment recommendations for Amazon, Walmart, Shopify, or eBay sellers at a low per-call cost. It is especially useful for automating restock workflows in agent pipelines where human review of inventory data is impractical.

## Known failure modes

- Missing or malformed inventory input data returns a 400 validation error
- Insufficient sales history may result in low-confidence or incomplete restock recommendations
- Service unavailability on Railway hosting may return a 503 timeout
- Incomplete SKU data may cause partial plan generation with missing line items

## 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 restock plan computation has been initiated. The plan typically includes recommended reorder quantities, timing, and prioritized SKUs across marketplace channels.
