## 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-brand-name-screen-18d38f1d -d '<json body>'
```

Example prompt: Can you screen the brand name 'NovaPeak' to make sure it's eligible and conflict-free before I start listing products on Amazon?

## When to prefer this

Use this endpoint when you need to pre-screen a brand name for marketplace policy compliance and conflict detection before creating product listings on Amazon, Walmart, Shopify, or eBay. Prefer this over generic trademark search tools when you specifically need ecommerce-platform eligibility context and want low-cost, instant results as part of an automated seller workflow.

## Known failure modes

- Missing or empty brand name input returns a 400 validation error
- Unsupported marketplace specified returns an error
- Service unavailable or Railway deployment cold-start causes timeout
- Payment failure via x402 protocol blocks the request
- Job queue overload may delay result availability

## 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 immediately, indicating the brand name screening job has been accepted and is being processed asynchronously. The agent should poll for results using the job ID.
