# HTML Table Extractor (x402 / Zaden Works)

> HTML Table Extractor (x402 / Zaden Works) is a paid API for AI agents from x402-zadenworks.zaden-gaming.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Fetches a URL and extracts all HTML tables as structured JSON, returning headers, row arrays, and (when headers are unique) row objects keyed by header name.

## 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 html-table-extractor-x402-zaden-works-f524f340 -d '<json body>'
```

Example prompt: Can you extract all the tables from https://example.com/pricing as structured JSON — I need the headers and rows so I can compare the plan tiers?

## When to prefer this

Choose this endpoint when you need structured data from one or more HTML tables on a specific page — such as pricing grids, spec sheets, comparison tables, or schedules — and want clean JSON (headers + rows) without writing custom HTML parsing code. It is especially useful when the table structure is relatively standard and you need both array-of-arrays and keyed-object representations. For JavaScript-rendered pages or highly dynamic content, consider a sibling endpoint that uses a full headless browser render first.

## Known failure modes

- URL is unreachable or returns non-200 status — table extraction fails with an error
- Page has no HTML tables — returns an empty array
- Tables use rowspan/colspan in complex ways that may not parse cleanly into flat row arrays
- JavaScript-rendered tables may not be captured if the page requires JS execution to populate table data
- Duplicate header names prevent the keyed row-object representation from being generated for that table
- Malformed HTML may cause incomplete or incorrect table parsing

## How this service works

Fourteen pay-per-call web tools for AI agents, billed in USDC on Base with no account or API key. START WITH /audit -- one call returns a complete page health check (SEO + structured data + accessibility, optionally plus links and sitemap) with a single score and one worst-first findings list. The parts are also sold individually. SITE AUDIT: /seo (on-page SEO and meta tags), /links (broken links), /sitemap (robots.txt and XML sitemap crawlability), /structured (JSON-LD and social preview tags), /a11y (WCAG accessibility) -- each scored 0-100 with a prioritised issue list. READING: /read (clean markdown), /snap (screenshot, PDF or rendered HTML), /tables (every HTML table as structured JSON), /verify (does a claim actually appear on this page). MONITORING: /watch (has this page changed), /compare (what differs between two pages). Plus /rank (best x402 service for a task) and /batch (several operations behind one payment).

## Output

Returns a JSON array of table objects, each containing: an array of header strings, an array of row arrays (each row is a list of cell values), and (when all headers are unique) an array of row objects where each key is a header name and the value is the corresponding cell content. Covers all tables found on the page.
