 # SnapAPI Session Log
 
+## Session 24 — 2026-02-25 14:00 UTC (Usage Dashboard Feature)
+
+**Goal:** Build customer-facing usage dashboard — a real gap where customers had no way to check their API usage.
+
+**Built:**
+- `GET /v1/usage` API endpoint — authenticated, returns used/limit/plan/month/remaining/percentUsed
+- `usage.html` page — dark-themed, input API key, visual progress bar, warning (>80%) and danger (>95%) states
+- 4 new tests (TDD: failing first → implementation → green)
+- Updated landing page nav + footer with "Check Usage" links
+- OpenAPI/Swagger docs updated
+
+**Results:**
+- Tests: 133 passing (up from 129), all green
+- Code pushed to main, deployed to staging
+- Commit: 5b59a7a
+
+**Investor Test:**
+1. Trust with money? Mostly — checkout works, Stripe webhook unregistered
+2. Data loss on crash? No — PostgreSQL
+3. Free tier abuse? Low risk — IP-limited, watermarked, URL length capped
+4. Key recovery? Yes on staging
+5. Website features? All working
+
+**Still blocked:** Stripe webhook registration, CI/CD (Forgejo runner), staging TLS (DNS), production deploy (needs approval)
