How this service works

Turn Apify product scrape results into safe catalog updates with Catalog Update Gate. Find evidence in supplied documents, compare snapshots, extract typed JSON fields, inspect x402 quotes and assess API migrations. Preview inputs, evidence and cost for free. No live web search, scheduled monitoring or third-party purchasing.

Output

Returns an array of structured data objects found in the HTML, each with a 'valid' boolean flag and a 'value' object containing the parsed typed fields (e.g. {'@type': 'Article', 'headline': '...'}). Multiple schema types (JSON-LD, Microdata, RDFa) may be returned in a single response.

Example use cases

SEO structured data audit

“I've got the raw HTML from a product page and I want to know exactly what JSON-LD and schema.org structured data is embedded in it — can you extract and validate all of it for me?”

Article metadata extraction

“Here's the HTML of a news article — can you pull out any Article or NewsArticle structured data fields like headline, author, and datePublished that are embedded in it?”

x402 API quote inspection

“I grabbed the raw HTML from an x402-enabled API response page — can you extract all the structured data from it so I can inspect the payment quote fields and types?”

Technical details

Endpoint

When to prefer

Choose this endpoint when you have raw HTML content in hand and need to extract, validate, or inspect embedded structured data (JSON-LD, Microdata, RDFa, schema.org) without making a live web request. It is ideal for offline or cached HTML analysis, SEO audits, x402 quote inspection, and evidence gathering from document snapshots. It does not perform live web fetching, so pair it with a separate scraping step if you need to retrieve the HTML first.

Side effects

HTML string exceeds 50,000 character limit — request rejected
Malformed or unparseable HTML yields empty structured_data array
No structured data present in document returns empty array
Invalid base_url format causes parsing errors for relative references
Oversized payload triggers HTTP 413 response
