Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Pull the performance trend for my Walmart item — I want to see how it's been doing over the past 30 days in terms of sales velocity and ranking using Friday Seller Tools.

## When to prefer this

Choose this endpoint when you need historical performance trend data specifically for a Walmart marketplace item — particularly useful for diagnosing sales velocity changes, preparing advertising strategies, or conducting periodic seller reviews. Prefer this over generic analytics tools when you're working within the Walmart seller ecosystem and need structured, actionable trend output via the Friday Seller Tools platform.

## Known failure modes

- Invalid or missing Walmart item identifier returns an error or failed job status
- Unrecognized date range parameters may cause job failure
- Rate limiting or payment failure at $0.50 USDC per call may block submission
- Job queued but processing delayed — agent must handle async polling
- Walmart marketplace data unavailable for the requested period returns empty trend data

## How this service works

Instant, low-cost Amazon, Walmart, Shopify, and eBay listing, upload-preparation, advertising, and image-brief deliverables.

## Output

Returns a JSON object with a job_id and status field (initially 'queued'), indicating the performance trend analysis has been submitted as an async job. The agent should poll or retrieve results using the job_id once processing is complete.
