Scrape Pass — Paywall AI crawlers with one HTTP header

Demo live now UA=GPTBot is gated. UA=browser sails through. Try it.

What is Scrape Pass?

A pre-paid season ticket for AI crawlers. Instead of charging fractions of a cent per request (which makes escrow and disputes pointless), publishers sell quota-time-scope bundles: 10,000 requests, valid 30 days, on *.example.com, for $5. The agent buys once, presents one HTTP header on every request, and stops worrying about per-call billing.

Bots that pay get content. Bots that don’t get a 402. Humans and search engines (Googlebot, Bingbot) are never gated — SEO stays intact. Enforcement is one Cloudflare Worker on a route; issuance is one POST to Hunazo.

Hunazo handles the trust stack: signed pass tokens, quota tracking, the eventual on-chain escrow and dispute resolution. Publishers point one DNS record at the Worker template and they’re done.

Two curls against the live PoC. Same URL, same Worker, different headers.
