Web extraction API for AI agents

The easiest way to get data off the web.

Haunt reads permitted public pages and hands back structured JSON or clean Markdown. No scraping code, no cleanup.

The shift

Stop copying web

data by hand.

Before Haunt

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

  • Brittle scrapers shatter every time a layout shifts.

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

  • You inherit a pile of stored page content you never wanted to hold.

With Haunt

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

  • Need page text for an agent or RAG pipeline? Ask for Markdown instead.

  • One endpoint handles fetch, JavaScript render, and extraction.

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

  • Page content, prompts and results are not retained by default.

How it works

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.

01

Run the live demo

See structured JSON and a confidence trace before you hand over an email. No signup, no key.

02

Claim a free key

Get 1,000 free credits and a ready-to-run curl command pointed at your own URL.

03

Build the integration

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

Use cases

Pick your lane.

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

No fake magic

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.

No credit card. Free gives 1,000 credits each month. The key appears once, then Haunt gives you a ready-to-copy curl command for your first real extraction.

Haunt does not retain page content, prompts, or extracted results by default. It keeps only the metadata needed for billing, rate limits, abuse prevention and reliability.

Short answers

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.
