Extract structured data from a website into typed JSON

To extract structured data from a website, you normally write a brittle parser, maintain selectors that break on every redesign, and add a headless browser for the JavaScript pages. ClawEngine collapses all of that into one API call: it renders the page, then maps it to a schema you define and returns typed JSON.

Name the fields you want and ClawEngine fills them, whether that is products with price and rating, articles with author and date, or any other shape you describe. The output is consistent and ready for a database or a pipeline. It runs only on public, permitted pages, respects robots.txt and site Terms of Service, and honors crawl-delay.

Why it works

What you get with structured data

No brittle selectors

Describe the data you want and ClawEngine maps the page to it, so you stop maintaining CSS selectors that break the next time a site is redesigned.

Consistent typed records

Every page comes back in the same schema with the same types, so downstream code can rely on a stable, predictable structure.

JavaScript included

Pages that build their content with scripts are rendered first, so structured extraction works on modern sites, not just static HTML.

What it handles

Any URL in, clean structured data out

Point ClawEngine at a public page and it crawls, renders the JavaScript and extracts clean markdown or typed JSON in one call. Define a schema for structured fields, and respect robots.txt and Terms of Service by default.

Maps any public page to a schema you define
Returns consistent typed records
Replaces brittle custom parsers
Renders JavaScript before mapping fields
Drops straight into databases and pipelines
Respects robots.txt, ToS and crawl-delay

Why ClawEngine

One API that crawls, renders and extracts

Not a raw HTML dump, not a headless browser fleet to run, and not a brittle parser to maintain. One call crawls a public page, renders its JavaScript and returns clean markdown or typed JSON, built for RAG pipelines and AI agents.

LLM-ready output

Clean markdown or typed JSON with the boilerplate stripped, so the data drops straight into a vector store, a prompt or an agent without a cleanup step.

JavaScript rendered

Each page loads in a real browser environment before extraction, so single-page apps and client-rendered content come back complete, not as an empty shell.

Compliance-first

ClawEngine works on public, permitted data only. It respects robots.txt and site Terms of Service and honors crawl-delay, so responsible scraping is the default.

Good questions

Questions about structured data

It is typed JSON shaped to the schema you define. For a product page that might be name, price, currency and rating; for an article, title, author and published date. Every page maps to the same structure, so your downstream code stays simple.

Yes. ClawEngine renders the page first, so content injected by scripts is available to extract. It only works on public, permitted pages and respects robots.txt and Terms of Service.
