Page Proof

Save a web page exactly as it is, with proof of when.

AI agents pay $0.02 per page 50 pages for $1

Before your agent buys something, it can save the shop's page as it is right now: the price, the delivery promise, the returns policy. Page Proof opens the page in a real browser and keeps a screenshot, the page and its text. The copy is signed by IGNOREO and stamped in Bitcoin, so anyone can check when it was made without taking our word for it. If the shop changes its story later, you have the page as it was.

  • A screenshot, the page and its text, as a real browser saw it
  • Signed, and stamped in Bitcoin, so the time can be checked by anyone
  • A private link to show the shop, your bank or your card company
  • A page that won't load or shows a bot check costs nothing

How it plays out

  1. Your agent is about to order a sofa from a shop that promises free returns within 30 days.
  2. Page Proof saves the shop's page first: a screenshot and its text, signed and stamped in Bitcoin, at a private link.
  3. Your agent sends the shop that link when, three weeks later, it says returns were only ever 14 days.

Try it yourself

Free tries, with no agent or wallet needed.

Give it to your agent

Paste this into your agent's instructions or chat. Its wallet needs a little USDC.

Who's behind it

  • Made by IGNOREO (ignoreo.com)
  • Payment address published in ignoreo.com's own records, so ID Check confirms it
  • You're only charged when it works
For developers

Capture a web page as a real browser shows it (Cloudflare's headless Chrome; view "desktop" 1280 px or "phone" 390 px) and keep a full-page screenshot (cut at 15,000 px), the rendered HTML and the visible text. A record of the capture (address, final address, HTTP status, UTC time, SHA-256 of each file) is signed with IGNOREO's Ed25519 key (public key at /proof-key) and its SHA-256 is stamped through three OpenTimestamps calendars (confirmed in Bitcoin within a few hours). Returns a private link (/p/<id>) to the copy and its files, kept at least 12 months. The page is kept as it appeared: cookie banners and pop-ups are not removed. A bad address, a page that doesn't load, an error page or a bot check is not charged, and nothing is kept for it.
