## 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 manylives-web-field-extractor-2aa71aa0
```

Example prompt: Go to https://coinmarketcap.com/currencies/bitcoin/ and extract the fields 'price,market_cap,volume_24h' from that page for me.

## When to prefer this

Choose this endpoint when you need to extract a small, known set of named fields from a specific public URL without writing custom scraping code. It is ideal for ad-hoc, pay-per-call web data extraction where you know exactly which fields you want and the page is publicly accessible. Prefer this over full-page scrapers when you only need targeted key-value pairs rather than full HTML or raw text.

## Known failure modes

- URL is not publicly accessible (returns null values or error)
- Fields not present on the page return null values rather than an error
- Non-HTTPS or malformed URLs may be rejected
- Pages requiring JavaScript rendering may return incomplete data
- Rate limiting or bot-blocking by the target website may result in empty extractions
- Network timeouts for slow-loading pages

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

A JSON object containing the requested URL and an array of field objects, each with a 'name' and 'value' key. Values are strings if found on the page, or null if the field could not be located in the page content.
