API Error Note Cards

API Error Note Cards is a paid, local-first notebook for manual API error notes. Add cards with endpoint label, owner, environment, status code note, symptom note, payload note, fix note, follow-up note, impact level, repro attempts, release blocker, priority, checklist state, readiness percent, next action, and status. Review cards that are draft, ready, need context, follow up, or done, then copy or share a CSV handoff when you choose. The app is intentionally manual and private. It does not require an account, access API services, import logs, monitor traffic, call live endpoints, call APIs, connect to API platforms, connect to logging tools, use AI debugging, use OCR, scan files, access contacts, access calendars, create reminders, use analytics SDKs, use ads, track users, cloud sync, or upload entries to a developer server.
