- SQLite + FTS5 full-text search (pure Go, no CGO)
- BCB integration: Selic, CDI, IPCA, USD/BRL, EUR/BRL
- CVM integration: 2,524 companies from registry
- Fiber v2 REST API with 42 handlers
- Auto-seeds on first run (~5s for BCB + CVM)
- Token bucket rate limiter, optional API key auth
- Periodic sync scheduler (configurable)
- Graceful shutdown, structured logging (slog)
- All endpoints tested with real data
