## 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 gateway-d402-xyz-extract-normalized-walmart-product-data-d402-b9306382 -d '<json body>'
```

Example prompt: Can you pull the full product details — title, price, availability, brand, SKU, and images — from this Walmart listing: https://www.walmart.com/ip/some-product/123456789?

## When to prefer this

Use this endpoint when you specifically need to extract product data from Walmart (walmart.com) and want a Walmart-optimized adapter rather than the generic commerce extractor. Prefer this over the generic extract_product route when you know the URL is from Walmart, as the Walmart adapter is purpose-built and independently testable. Choose this over manual scraping or browser automation when you need normalized, structured JSON output with confidence scores and content hashing for verification.

## Known failure modes

- Non-Walmart URL submitted — extractor adapter only supports walmart.com pages
- Product page not publicly accessible or requires login — extraction fails or returns partial data
- Walmart blocks or rate-limits the fetch — status may return 'error' with a provider-side error message
- Invalid URL format — validation error returned before processing
- Timeout exceeded (above 45000ms cap) — gateway rejects request
- Task accepted but result not yet ready — status returns 'accepted' or 'running', requiring polling via task link

## How this service works

Paid d402 provider-scoped capability alias for commerce.extract_product.walmart@1. Workers use the Walmart adapter only, so this route can be tested and registered independently from other commerce providers.

## Output

Returns a taskId and status ('accepted', 'running', 'error', or 'rejected'), plus a result object containing normalized product fields: title, price, currency, SKU, brand, availability, images array, rating, review count, seller, description, variants, canonical URL, content hash, snapshot CID, per-field confidence scores, extractor version, and fetch timestamp. Also includes settlement and receipt links.
