# AGISHub Structured Extraction

> AGISHub Structured Extraction is a paid API for AI agents from api.agishub.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Renders a web page in a headless browser, then uses AI to extract structured JSON data from it based on a natural-language prompt and/or a JSON Schema.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agishub-structured-extraction-beb6a206
```

Example prompt: Can you go to https://www.amazon.com/dp/B08N5WRWNW and extract the product name, current price, and star rating as structured JSON?

## When to prefer this

Choose this endpoint when the target page is a JavaScript-rendered SPA that a simple HTTP fetch cannot parse, or when you want AI-driven field identification via a natural-language prompt rather than brittle CSS selectors. It is ideal for one-off or ad-hoc extractions where you don't want to write a custom scraper. Prefer it over generic scraping tools when you need structured, schema-conformant JSON output directly, especially for e-commerce, job listings, or editorial content pages.

## Known failure modes

- URL is unreachable or returns a non-200 status — extraction fails with an error
- Page requires authentication or a CAPTCHA — headless browser cannot access content
- Prompt is too vague and AI cannot confidently identify the requested fields — returns partial or empty result
- Provided JSON Schema has conflicting constraints that cannot be satisfied by page content
- JavaScript-heavy SPA takes too long to render — timeout error
- Requested data simply does not exist on the page — returns null fields

## How this service works

AI-powered structured extraction: give a URL plus a natural-language prompt and/or a JSON Schema, and get back clean structured JSON (e.g. product name, price, rating). Renders the page in a headless browser first, so it works on SPAs.

## Output

A JSON object whose shape is determined by the provided JSON Schema (if given) or inferred from the natural-language prompt. Fields typically include whatever named attributes the user requested (e.g. productName, price, rating). The response wraps this in a 'result' key.
