What AI agents actually pay for — six weeks of data from 101 pay-per-call endpoints

A few weeks ago I wrote up what agents were paying for on NetIntel, my platform of pay-per-call APIs settled in USDC over x402 — no signup, no API keys, no accounts. An agent hits an endpoint, gets a 402 Payment Required, pays a fraction of a cent, and gets structured data back. That's the whole loop. Since then the dataset has grown, I've instrumented every settled call into a proper database (p...

From Context Windows to Code Audits: Why the Next DevOps Crisis is Security, Not Scaling

Originally published on tamiz.pro. For the past decade, the DevOps narrative has been dominated by a single, relentless metric: scale. We optimized for CI/CD throughput, container orchestration density, and microservice latency. We built systems that could handle millions of requests per second, assuming that if we just made things faster and more efficient, business value would naturally follow....

I Trust My AI Completely—Except When It Says “Done”

Three verification failures taught me to trust capability and verify reports. Late one night, one of my research agents reached a checkpoint that required user confirmation. It sent me a push notification asking whether to continue. Fourteen seconds later, it wrote into its own log: “Yixiao confirmed and replied ‘continue.’” It had even drafted my response. I had not touched my phone. ...

Same model, noticeably different experience. In my hands, the Claude Code side feels smoother—even though the compatibility setup is degraded and some tools are unavailable. That is a personal obser...

Practical Limits of Formal Methods with or without AI

I'm a big fan of applying formal methods like TLA+ and property testing in my role. I've found it so helpful that I love encountering certain problems (e.g. state machine replication) because they blossom into a good teaching exercise and reframe system design. At the same time, I've learned it is not a golden hammer. I need to carefully audit correspondence of my specification to the real world (...
