## 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-walmart-search-insights-rank-gap-prioritization-7dc7aae0 -d '<json body>'
```

Example prompt: Look at my Walmart listings for 'wireless earbuds' and tell me where I have the biggest rank gaps compared to top sellers — give me a prioritized list of keywords I should go after first to close those gaps.

## When to prefer this

Choose this endpoint when you need to specifically identify and rank-order Walmart search visibility gaps for a seller's products relative to competitors. It is purpose-built for Walmart SEO prioritization, as opposed to generic keyword research tools or Amazon/Shopify-specific optimization. Best used when a seller already has active Walmart listings and wants actionable, prioritized direction on where to invest optimization effort.

## Known failure modes

- Missing or invalid product identifiers returns a validation error
- Walmart category or keyword data not available for niche products may yield sparse results
- Job may remain in 'queued' status for extended periods under high load
- Invalid or unrecognized Walmart marketplace parameters return 400-level errors
- Payment failure via x402 protocol prevents job submission

## 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 status ('queued') indicating the analysis has been submitted. The completed job delivers a prioritized list of Walmart search rank gaps — keywords or search terms where the seller's products are underranking relative to competitors, ordered by opportunity or gap size to guide SEO and advertising efforts.
