Before HauntWith Haunt

Open pages, hunt for fields, paste into a sheet, and still miss things.

A pricing page becomes a clean list of plans, prices, limits and features.

Brittle scrapers shatter every time a layout shifts.

One endpoint handles fetch, JavaScript render, and extraction.

Other tools fake success on blocked pages and hand you garbage.

Blocked or login-only? Haunt says so, and never invents data.

A pile of stored page content you never wanted to hold.

Page content is never stored, and results are kept only if you opt in.

Three moves,

no guesswork.

Try the demo, grab a free key to test a page of your own, then connect Haunt to your app or AI agent.

Build the integration

Switch between REST, MCP or the SDK and start consuming clean data in your app or agent.

Pick your lane.

Most teams start with one concrete extraction, then add the use cases that are actually theirs.

It saves time because it tells the truth.

Bad extraction tools waste your time by pretending blocked pages worked. Haunt is built to fail clearly when a page can't support the answer.

Works on normal public pages: company sites, pricing pages, docs, articles and directories.
Renders many JavaScript pages. Heavy app shells, login walls and verification pages can still fail, and Haunt says so clearly.
Returns a clear error when a page is blocked, empty or login-only.
Never invents data just to look successful.

Questions normal

humans ask.

What does Haunt do?

It extracts useful fields from public web pages as structured JSON, or returns clean Markdown when your agent or RAG pipeline needs page text.

Can I try it without signing up?

Yes. Try the demo above first. Create a key only when you want to test your own URL.

What if the page is blocked?

Haunt detects many CAPTCHA and human-verification blocks and returns a clear error like captcha_required. It does not solve CAPTCHAs or bypass login walls.

How do credits work?

Simple monthly plans based on credits. Failed extractions do not burn credits. No automatic overages. Simple pages usually use 1 credit, normal structured extraction 2, browser-rendered pages 4, and heavy pages 8. Very large pages add 1 credit per ~10,000 tokens of page content (up to 3 extra), so a big page costs a little more than a small one.

Can developers still use MCP or REST?

Yes. REST supports response_format: "markdown", and the MCP package exposes extract_markdown for agent workflows.
