+## 🔌 APIs Utilizadas
+
+| Fonte | Endpoint | Dado |
+|-------|----------|------|
+| Banco Central | `api.bcb.gov.br/dados/serie/bcdata.sgs.433` | IPCA mensal |
+| Banco Central | `api.bcb.gov.br/dados/serie/bcdata.sgs.189` | IGP-M |
+| Banco Central | `api.bcb.gov.br/dados/serie/bcdata.sgs.432` | Selic |
+| AwesomeAPI | `economia.awesomeapi.com.br/json/last/USD-BRL` | Dólar comercial |
+
+> ⚠️ **Fallback**: Quando APIs estão indisponíveis (CORS, timeout, manutenção), o sistema utiliza dados mockados realistas para manter a experiência funcional. Um indicador visual mostra se os dados são "em tempo real" ou "de demonstração".
