## 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 signaldesk-ai-json-ld-extractor-c1a3a9e4 -d '<json body>'
```

Example prompt: Extract any JSON-LD structured data records from this HTML — I need the schema.org entities like Organization, Product, or Event that are embedded in the markup: <html>...</html>

## When to prefer this

Choose this endpoint when you need to extract schema.org / JSON-LD structured data from a known HTML snippet without executing JavaScript, particularly for lightweight single-page extractions where you already have the HTML. It is a good fit for serverless agent pipelines that need cheap ($0.002 USDC), fast structured-data extraction with no browser overhead. Prefer alternatives if you need full browser rendering, JavaScript execution, or bulk crawling of many pages.

## Known failure modes

- HTML exceeds 12,000 character limit — request will be rejected or truncated
- No JSON-LD markup present in HTML — returns empty records array
- Malformed HTML that prevents parsing — may return empty or partial results
- Payment failure (x402) — endpoint returns 402 before processing begins
- Script-dependent JSON-LD that requires JavaScript execution — not supported, static parsing only

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing a `records` array of schema.org entities parsed from the submitted HTML, each with fields like `name` and `@type`. Also includes an `untrusted_content` flag (boolean) indicating the data originated from caller-supplied markup.
