## 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-sku-normalize-7f51f397 -d '<json body>'

Example prompt: I have a messy product catalog with inconsistent SKU formats and I need them normalized and standardized so they're ready to upload to Amazon and Walmart — can you run my SKU data through Friday Seller Tools' SKU normalizer?

## When to prefer this

Choose this endpoint when you need to standardize or clean product SKU identifiers for cross-marketplace compatibility, especially when preparing bulk catalog uploads for Amazon, Walmart, Shopify, or eBay. Prefer this over manual data cleaning or general-purpose transformation tools when dealing with marketplace-specific SKU format requirements.

## Known failure modes

- Invalid or malformed SKU input data returns an error response
- Missing required fields in the request body cause validation failures
- Unsupported marketplace targets may return partial results
- Payment failure (insufficient USDC) blocks the request
- Asynchronous job may time out or fail silently if job_id is not polled

## 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 a 'queued' status, indicating the normalization job has been accepted and is being processed asynchronously. The agent should poll or retrieve results using the job_id once processing is complete.
