Architecture

Request
  └─ FastAPI (main.py)
       ├─ Auth + rate limit   (APIKey in SQLite)
       ├─ Cache check         (Redis / fakeredis — 24h TTL per domain+depth)
       ├─ Web scrape          (httpx + BeautifulSoup)
       ├─ Claude enrichment   (claude-sonnet-4-6)
       ├─ Cache write
       └─ Usage log           (SQLite)

Caching: Same domain + depth = cached 24h. Cached responses are free.

• x402/USDC micropayment endpoint (in progress)
• Batch enrichment (up to 100 URLs)
