Cloudflare agents can now buy domains. The case for runtime spend rails just got concrete.
Cloudflare shipped agent flows that create accounts, buy domains via Stripe, and deploy infrastructure end-to-end. Good news for builders. Sharper case for runtime budget enforcement than any hypothetical we have used.

If AI agents can spend money, who's holding the credit card?
I built a memory API agents can pay for. The actual problem isn't whether they can pay. It's per-tool caps, per-agent budgets, kill switches, and spend visibility.

HTTP 402 & x402: The Web's Payment Code Finally Works (2026)
Reserved since 1991, HTTP 402 sat unused for 33 years. Now x402 ships the client half — so AI agents can pay per request. Here's how it works and why it matters.

AI Chose Nukes 95% of the Time. Here's What That Means for Your Agents.
Three studies dropped in the last few months. GPT-5.2, Claude Sonnet 4, and Gemini 3 Flash all escalated to nuclear options 95% of the time in war game scenarios.

Here is what that means if you are running agents in production today.

What AI-native startups actually look like in 2026 (and I'm running one from Tennessee)
Flatiron Health toured AI-native startups in SF. One PM covers five companies, Claude Code is replacing Cursor, non-engineers are shipping production. I'm running the same model from Tennessee as a solo holding company. Here's what that actually looks like.

When to Replace Your AI Agent With a Script
Will Larson says agents should be scaffolding, not permanent infrastructure. I run 12 agents overnight. Here's what I kept as agents and what I converted to code.
The AI agent build notes
Real costs, real tools, no fluff. M-F when I ship, publish, or learn something worth sending.
