FAQ
Web scraping API questions, answered
What a web scraping API is, how the LLM-ready output works, whether it renders JavaScript, how schema extraction works, what it costs, and how ClawEngine stays compliant. The things developers ask before they build.
The basics
A web scraping API is a service you call with a URL to get a website's content back as clean, structured data. Instead of running your own crawler, proxies and headless browsers, you make one API request and ClawEngine crawls the page, renders its JavaScript, extracts the content and returns markdown or JSON. It is built for public, permitted data only.
Every result comes back as clean markdown or typed JSON with navigation, ads and boilerplate stripped out. It is shaped to chunk, embed and feed straight into a RAG pipeline or an agent, with no extra cleanup step on your side.
Yes. Pages are rendered in a managed headless browser before extraction, so client-side content, dynamic tables and infinite scroll come through fully loaded, not as an empty HTML shell.
No. Crawling, proxy handling, retries and headless rendering are fully managed. You make an API call and get clean data back, with no fleet to run, scale or babysit.
Building with it
Call the REST API with curl, Python or Node, or use our SDKs. It drops into LangChain and LlamaIndex pipelines, and you can get results delivered by webhook for scheduled crawls. The docs page shows the endpoints and code samples.
Yes. Send a JSON schema with your request and ClawEngine maps the page to it, returning typed records: strings, numbers, dates, nested objects and arrays. Define the fields once and reuse the schema across thousands of pages, with no brittle selectors to maintain.
Yes. Point ClawEngine at a domain and it crawls the pages you allow, on a schedule if you want, with concurrency and rate limiting handled for you. You poll a crawl by id or receive results by webhook.
No free plan. ClawEngine is a paid, usage-based product starting on the Hobby plan at $39 a month. You can try the live extraction console on the site for free to see exactly what the API returns before you sign up.
Compliance and trust
ClawEngine is built for public and permitted data only. It respects robots.txt and site Terms of Service, honors crawl-delay, and is meant for public docs, product catalogs, listings, your own sites and sites you have permission to crawl. You are responsible for what you choose to crawl. See our compliance page for the full policy.
Yes, by default. ClawEngine reads robots.txt before crawling, honors crawl-delay, and is designed for compliance-friendly use. It is never framed around bypassing authentication, defeating paywalls or evading bot detection, and it is not built for scraping private or personal data.
It is not for logging into accounts on your behalf, getting past paywalls or login walls, evading bot detection, or collecting private or personal data. ClawEngine is for public, permitted data, and you are responsible for ensuring you have the right to crawl what you point it at.
Crawled data is processed to produce your result and is handled per our privacy policy. We do not sell it and we do not use it to train public or third-party models. The output is yours.
