Cloudflare AI Crawler Blocking and Pay Per Crawl

Robots.txt asks compliant crawlers to follow public path instructions. Cloudflare AI Crawl Control works at the network edge for sites whose traffic passes through Cloudflare: it can show AI crawler activity and lets an owner allow or block listed crawlers. A block is enforced through Cloudflare’s security rules, so it does not depend on the crawler honoring a robots.txt request. Coverage still depends on identifying the traffic and the site’s Cloudflare configuration; do not assume every automated request will be recognized or that a user-agent string proves identity. Pay Per Crawl adds a charge option for selected crawlers. Cloudflare’s documentation describes a price per zone and a payment exchange: a crawler without acceptable payment intent can receive HTTP 402 Payment Required and a crawler-price header. A compatible crawler can make another signed request with payment headers; successful access returns HTTP 200 and a crawler-charged amount. The feature requires crawler-side support and verification, so it is not a general way to invoice every bot that visits a site. Cloudflare currently labels Pay Per Crawl a closed beta; availability and terms may change. Site owners can choose actions by crawler: allow without a charge, block, or charge. A block configured through WAF or Bot Management overrides a charge policy, so conflicting rules need review. The feature’s current documentation also says pricing is per zone, with a single configured price for crawlers marked Charge, and every successful retrieval can incur that amount. Consider repeated fetches, content value, billing records, and whether search crawlers should be charged or blocked, since that could affect indexing. Paths such as robots.txt and sitemap.xml are listed as always free in current documentation. Start with visibility and a small policy scope. Review crawler identities and request patterns, decide which content should remain public or free, and test the resulting HTTP status and headers with a compatible crawler. Monitor successful deliveries and charges, and verify account eligibility before promising revenue.
