## 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-amazon-browse-node-drift-diff-e5dfc22f -d '<json body>'
```

Example prompt: Check for browse node drift in my Amazon catalog — I want to see which browse nodes have changed or shifted so I can update my listings accordingly.

## When to prefer this

Choose this endpoint when you need to detect Amazon-specific browse node reclassifications or taxonomy drift affecting your product listings. It is purpose-built for Amazon catalog intelligence and is more focused than generic catalog monitoring tools. Prefer it when you suspect silent category reassignments are impacting discoverability or search ranking, especially before major sales events.

## Known failure modes

- Invalid or missing browse node IDs returns a 400 error
- Unrecognized ASIN or catalog reference returns empty diff
- Payment not processed results in 402 response
- Job queue timeout or Railway infrastructure issue returns 503
- Snapshot date range too large may result in processing delays or timeout

## 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 async diff job was accepted. The final result will include a structured diff of browse node assignments showing which nodes changed, were added, or were removed across catalog snapshots for the specified ASINs or categories.
