## 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 web-access-gateway-product-search-4c87f2b0 -d '<json body>'
```

Example prompt: Can you find me current prices, specs, and reviews for the Sony WH-1000XM5 headphones from across the web?

## When to prefer this

Choose this endpoint when an agent needs to quickly surface product pricing, specifications, or reviews from multiple public web sources without needing real-time inventory data. It is well-suited for pre-purchase research, price benchmarking, and spec lookups. Prefer it over a general web search endpoint when the query is product-focused and the structured ranking of commercial sources is beneficial. Not appropriate for checking live stock availability or placing orders.

## Known failure modes

- Query string is empty or exceeds 500 characters — validation error returned
- No relevant product sources found for obscure or misspelled product names
- Payment not processed or x402 payment header missing — 402 Payment Required response
- Rate limiting or upstream web access failures resulting in partial or no results
- Stale or cached web data may not reflect the most current pricing

## How this service works

Find 5 ranked public-web product, price, specification, and review sources. Not a live inventory guarantee.

## Output

Returns 5 ranked public web sources related to the product query, each containing relevant excerpts covering price, specification, and/or review information drawn from live public web pages. Not a live inventory guarantee — results reflect public web coverage, not real-time stock availability.
