## 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 sainsbury-s-product-scraper-api-x402-f64213b3 -d '<json body>'
```

Example prompt: Search Sainsbury's for 'organic oat milk' and 'free range eggs', returning up to 10 results per query, so I can compare their prices and brands.

## When to prefer this

Choose this endpoint when you need structured, up-to-date product and pricing data specifically from Sainsbury's UK grocery store, especially for price monitoring, product discovery, or EAN/ID lookup tasks. It is pay-per-call with no charge for failed or empty runs, making it cost-efficient for agents that may issue speculative queries. Prefer it over generic web scrapers when you need clean, schema-consistent output ready for downstream processing.

## Known failure modes

- Empty results if the search query matches no products — call is not charged
- Network or scraping failure — call is not charged
- Invalid input schema (e.g. empty queries array or maxResultsPerQuery outside 1–100) returns a validation error
- Rate limiting or blocking by Sainsbury's website may cause transient failures
- Payment failure via x402 protocol prevents the call from being made

## How this service works

Pay-per-call structured web data. Failed or empty runs are not charged.
