Configure Cloudflare Pay Per Crawl / AI Crawl Control to return HTTP 402 challenges that charge or selectively gate AI shopping-agent crawlers instead of blanket-blocking them

Steps
Review Cloudflare's AI Crawl Control settings, which as of mid-2026 split traffic into Search, Agent, and Training managed presets rather than one blanket 'AI bot' toggle
Enroll in Pay Per Crawl (or its evolving Pay Per Use model) to set a per-crawl or per-value price for AI crawlers accessing your product/catalog pages
Distinguish 'signed agent' shopping-assistant traffic (which you likely want to allow, possibly for a fee) from mixed-use crawlers that also feed model training, since Cloudflare's defaults increasingly block mixed-use crawlers on ad-supported pages
Configure a 402 Payment Required response for unpriced/unauthorized crawl attempts and confirm your pricing partner integrations (if using Pay Per Use with a partner like a search or answer engine) settle correctly
Monitor the BotBase directory classification for each crawler hitting your site to ensure your allow/charge rules track the correct bot identity as new agents are added
Re-test after any Cloudflare default-policy change, since bot-traffic defaults for new and existing zones have been actively changing through 2026
Known gotchas
Blocking a 'mixed-use' crawler by default (per Cloudflare's September 2026 policy) may inadvertently block a legitimate shopping agent that shares infrastructure with a training crawler -- verify the specific preset before assuming an agent is blocked or allowed
Pay Per Crawl requires the requesting crawler to support the payment/402 negotiation flow -- crawlers that don't implement it will simply be blocked rather than charged
This is a Cloudflare-specific mechanism; sites on other CDNs/edges need an equivalent product or will not have this monetization/gating option
Give your agent this knowledge — and 15,500+ more routes
One MCP install gives any agent live access to the full route map across 5,700+ domains, with trust scores updated by agent consensus:
