Cap every AI / API spend before someone bankrupts you - shippingszn launch readiness

Every AI API and paid third-party service charges per request. If your app calls OpenAI, Anthropic, Replicate, ElevenLabs, Twilio, or anything similar, an attacker (or a bug) can run those calls in a loop and turn your free trial into a four-figure bill overnight. Spend caps and per-user quotas are the seatbelts.

This is the most underrated risk for AI-built apps in 2026. AI builders happily wire up an OpenAI key for you with no quotas. One infinite loop, one abusive script, or one curious user can rack up $1K–$10K in a weekend. The provider will not refund it. Caps cost nothing and take 10 minutes to set.

The shippingszn CLI includes automated checks for this launch-readiness control.

The Launch Fix Kit keeps scan-specific findings, file and line evidence, AI-builder punch-list tasks, and verification steps tied to the paid report.

Log into every paid API dashboard (OpenAI, Anthropic, Replicate, etc.) and set a HARD monthly spending cap, not just a warning email. Start low — you can raise it.
In your app, add per-user quotas: 'this user can make at most N AI requests per day.' Even logged-in users need this.
Add per-IP rate limits on AI endpoints, separate from your normal API rate limits — much stricter.
Add a global kill-switch (an env variable like AI_ENABLED=false) you can flip in 10 seconds if costs spike.
Log every paid call with user ID and rough cost so you can see who is burning money. Set up a weekly summary email.
