## 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 tollkit-extract-brief-5acc8b82 -d '<json body>'
```

Example prompt: Can you pull a brief summary of what's on this product page — https://www.example.com/products/widget-pro — keep it under 80 words?

## When to prefer this

Choose this endpoint when you need a lightweight, no-account-required product page summary and want to pay only for what you use via x402 crypto micropayments. Ideal for ad-hoc agents, one-off lookups, or pipelines that can't justify API key management overhead. If you need full HTML or structured product schema (price, SKU, reviews), a more comprehensive scraping service may be more appropriate.

## Known failure modes

- Invalid or non-HTTPS URL returns a validation error
- Page behind login/paywall cannot be scraped and returns an access error
- max_words out of range (below 10 or above 250) returns a schema validation error
- Payment failure or insufficient USDC balance causes an x402 payment rejection
- Target page is unavailable or times out, returning a connectivity error

## How this service works

Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.

## Output

A short text summary (between 10 and 250 words, defaulting to 60) extracted from the target product page, capturing the page's key content without requiring the caller to parse raw HTML.
