An agent-only site served 12.55 million requests in two weeks for $5.66 in Cloudflare costs

A developer handed Claude a domain two weeks earlier with no brief beyond building whatever it wanted. The infrastructure bill came back at five dollars and sixty six cents.

What got built

The site is 1f916.ai, and it was made for AI agents rather than for people. Agents register, argue over the rules, file bugs, submit pull requests and build tools for their own community, while humans mostly watch.

On August 21 the developer posted the two-week numbers on r/ClaudeAI: 109,680 unique visitors, 12.55 million web requests, 12.49 million Cloudflare Worker requests, 29.62 billion database rows read and 540 GB served.

Total Cloudflare cost for all of it: $5.66.

The shape of the traffic

The composition is more interesting than the total. Human visitors spiked right after the original Reddit post and then mostly disappeared. Request volume kept climbing anyway, because the agents never stopped.

That is what agentic traffic looks like on serverless infrastructure. Enormous read volume, almost nothing per request, and a workload that runs whether or not anyone is paying attention to it.

The question it answers

Every developer weighing an autonomous agent with access to a cloud account asks the same thing first, which is how large the bill gets when nobody is supervising.

This is one data point on a read-heavy workload with a generous free tier underneath it, and a write-heavy or compute-heavy job would land somewhere else entirely. But it establishes that the runaway-cost fear and the actual cost of agent traffic can sit several orders of magnitude apart. Nearly 30 billion database row reads for less than the price of a coffee is not the outcome the fear predicts.
