## 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-table-extractor-html-tables-to-json-84c2e0d6
```

Example prompt: Can you pull all the tables from https://en.wikipedia.org/wiki/List_of_countries_by_GDP_(nominal) and give me the data as JSON rows I can work with?

## When to prefer this

Choose this endpoint when you need to extract structured tabular data from a live webpage, especially when the tables are rendered by JavaScript (since it uses a real Chromium browser). It's ideal for scraping financial data, sports stats, Wikipedia tables, or any HTML table from a site you can't easily parse locally. Prefer it over static HTML parsers when the page requires JS execution to render the tables.

## Known failure modes

- Page has no HTML tables — returns an empty array
- URL is inaccessible or returns a non-200 status — request fails
- Tables are inside iframes or shadow DOM that Chromium cannot reach — may be omitted
- Page requires authentication or login — tables behind a paywall may not be extracted
- Extremely large pages with many tables may be slow or truncated
- Dynamic tables loaded via infinite scroll may not be captured if scroll isn't triggered

## How this service works

Turn every table on a page into JSON rows you can compute on. Every HTML table on a page as JSON rows, with headers detected and captions kept. Fetched through a French residential IP with a real Chromium, so tables rendered by Ja…

## Output

An array of table objects, each containing detected column headers, optional caption text, and an array of row objects where each row maps header names to cell values. JavaScript-rendered tables are included since the page is loaded in a real Chromium browser.
