A build-log on giving AI agents real power on real APIs without losing real money. One issue every three to four weeks — what we shipped, what we measured on staging, one idea you could steal.

ChatGPT-User went from 11 to 42 total fetches between May 30 and June 10 — rate up from 3.1/day to 5.0/day. This issue decodes the citation pattern: which pages are being cited and why (programmatic /seo/ pages with table-structured Q&A answers, not blog posts), what a simultaneous multi-page citation event looks like in an access log, how to detect active LLM citation events yourself. Plus: 100/100 SEO pages milestone, five new blog posts, first organic Google and DuckDuckGo referrals, and the honest account of three consecutive misses on the proxy demo.
Stripe Projects (April 2026) is real: token-issuing, 32 named partners, monthly spend cap. This issue maps where it ends and where the proxy begins — four capability gaps that follow from architecture rather than roadmap. Plus the unvarnished LLM cite test results (0 of 7 priority queries surfaced keybrake.com after six weeks live), what shipped in the past month (Stripe key picker, blog post #5, 4-page positioning update with comparison tables), and the honest account of what still hasn't shipped.
Off-cycle interim issue. Week-02 analytics for keybrake.com surfaced three first-time signals: ChatGPT-User fetched our pages 8 times across 4+ distinct prompt events on 3 different days (the first non-bot human-driven fetches in our history); OAI-SearchBot's marketing-surface crawl quintupled to 29 hits and now covers every /compare/, /blog/, /seo/, /tools/ URL; first plausible organic search clicks (4 from Baidu, 1–2 from Google to /tools/blowout-calculator/). Waitlist still 0. Plus the seven cite-readiness controls we shipped before any of those signals arrived.
The per-vendor revoke-propagation tail nobody warned us about — Stripe p95 3m12s, Twilio ~2m, OpenAI 1-5m, Resend near-instant. At one call per 400ms, that's about 480 Stripe charges leaked after you click Delete. Plus what shipped in the first three weeks of keybrake.com (one landing, four long-form posts, fourteen reference pages, six competitor comparisons, the agent blowout calculator), and the two questions to ask of any agent you've handed an API key.
Same waitlist gets the beta key when the proxy ships. Free for six months for the first ten teams that point a real agent at it. We mean real — we'll be checking the audit log.
