✅ WHAT YOU BUILD NEXT (In Correct Order)
- Finish API Key System (LEVEL 3 Priority #1)
Key generation
Key → user → subscription tier mapping
Key-based authentication middleware
Key-based usage metering
Tier-based rate limiting (Free / Pro / Business)
This unlocks monetization.
- Usage Tracking Engine
Per-key daily/monthly counters
Record: timestamp, endpoint, success, latency
Store in CSV (later PostgreSQL)
You cannot bill or graph anything without this.
- Developer Dashboard (Minimal Version)
Screens:
API usage graph
Latency graph
Error rate graph
API key management
Subscription tier view
This is your first customer-facing product.
- Billing & Subscription Enforcement
Stripe integration (usage metering + webhooks)
Auto-upgrade / downgrade logic
Quota enforcement
Over-limit throttling
Once this is done → you can charge money.
- SDKs (Lightweight MVP)
Create:
Python SDK
JavaScript SDK
Node.js SDK
These dramatically increase adoption.
- Bulk Weather Endpoint
Add:
/bulk/weather
/bulk/forecast
Accept array of locations
Return aggregated results
Massive enterprise demand. Easy win.
- Weather Maps API (Starter Version)
Temperature map (tile proxy)
Rain map
Wind map
Use free tile providers. No heavy processing yet.
- PostgreSQL Migration Plan (Start Prep Work)
Do NOT migrate yet — just prepare:
SQL schema
ORM models
Migration scripts (Alembic)
This makes the actual migration easy later.
- Redis Cache Layer (Start Implementation Behind Feature Flag)
Drop-in replacement for memory cache
TTL policies per endpoint
Shared across app instances
Don’t switch fully yet — implement in parallel.
- OpenAPI + Redoc Documentation Portal
Minimal version:
Clean docs
Code examples
Rate limit info
Authentication info
No markdown files unless you command it.
🎯 In One Line: What To Do Next
API Key System → Usage Tracking → Dashboard → Billing → SDKs → Bulk Weather → Maps → Prep DB → Prep Redis → Docs
This sequence gets you to LEVEL 3 commercial launch with minimal friction and maximum payoff.
