Roadmap — what's next

Shipped

supabase-migration-api.sql — teams, api_keys, api_usage + bump_api_usage RPC
api/_shared.mjs — PLAN_CREDITS, CREDIT_COST, generate/verify key, quota helpers
api/keys-create|list|revoke.js — Supabase JWT auth, 5 keys max
api/v1/merge.js — pdf-lib server merge, 1 credit, quota 402, rate 120/min
docs/api.html — this page

Next to profitability

Apply migration in Supabase → test /api/keys-create + /api/v1/merge with 2 small PDFs
Wire tools/account.html API Keys tab (list/create/copy-once/revoke + usage bar) — 1 day
Add /api/v1/split, /compress, /render — copy merge pattern, costs 2 credits
White-label: CNAME + branding json + team subdomains — $199/mo
Paystack plan for API: extend payments with period='api_*' + credits_limit update

At 10 Starter + 5 Growth + 2 White-label = ~$1,180 MRR, ~$1k net after fees/infra.

How to verify locally

npm install (adds pdf-lib), set SUPABASE_URL etc from Vercel env, run vercel dev, create user at localhost:3000/tools/account.html, curl POST /api/keys-create with Supabase JWT, then curl POST /api/v1/merge with sk_live_.
