JSON-LD Schema Extractor

See which schema.org types each page declares and catch broken JSON-LD (a trailing comma is enough for Google to ignore it).

What you get

Field	What it tells you
page, finalUrl	Page you gave and its final address after redirects
statusCode, error	HTTP status and any request error
blocks	JSON-LD scripts found
validBlocks	Blocks that parse as valid JSON
types	Every @type found, including nested ones
issues	List of problems, or ok when nothing is wrong
jsonld	Parsed JSON-LD as text (only with includeRaw)

How to use it in 3 steps

1. Paste page URLs, one per line (up to 500).
2. Turn on includeRaw if you also want the parsed JSON-LD of each page.
3. Press Start and look at types and issues.

Pricing

$2 per 1,000 pages checked. Example: 300 pages = $0.60. Pages with errors or blocked by robots.txt are free; pages without JSON-LD are charged because they were checked. Set a maximum cost per run and the robot stops when it is reached.

Integrations

• Apify API and webhooks: start a run and read the dataset from any language.
• Make, n8n and Zapier: use the Apify module or node, run this robot and pass the dataset on.
• Google Sheets: export the dataset or use the Apify integration to fill a sheet on a schedule.
• Claude, Cursor and other agents (MCP): Use the Apify MCP server (https://mcp.apify.com?actors=kadro/jsonld-extractor) from Claude or Cursor and ask: "Which schema.org types do the product pages of example.com declare? Flag broken JSON-LD"

FAQ

Does it validate Google rich-result rules? No. It checks that the JSON is valid and lists the declared types; it does not check required properties for rich results.

Does it read Microdata or RDFa? No, only <script type="application/ld+json">.

Does it respect robots.txt? Yes. Blocked pages return "Blocked by robots.txt" and are not charged.

Can an AI agent use the output? Yes. types is a compact summary of each page, and includeRaw adds the full data.

Is it legal? It reads only public pages you list, one request each.

Limitations

• JSON-LD only: Microdata and RDFa are ignored.
• No validation against Google's rich-result requirements.
• Up to 500 URLs per run.
• Only public URLs: private and local addresses are blocked.
