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.
Example use cases
Business info extraction from webpage
“Here's the HTML from a company's homepage — can you pull out any JSON-LD structured data so I can see their official organization name, address, and type without having to parse it myself?”
Product schema scraping for catalog enrichment
“I have the raw HTML from a product listing page — extract the JSON-LD schema.org records so I can get the product name, price, and description in a clean structured format.”
Event metadata extraction from venue page
“Pull out the JSON-LD entities from this HTML snippet of a venue's events page — I'm looking for Event records with dates, names, and locations.”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/web/jsonld?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
