+# New Data Sources Integration Summary
+
+**Date**: December 13, 2025  
+**Integration**: Crypto API Clean + Crypto DT Source
+
+## 🎯 Overview
+
+Successfully integrated two comprehensive cryptocurrency data sources into the project:
+
+1. **Crypto API Clean** (HuggingFace Space)
+   - URL: https://really-amin-crypto-api-clean-fixed.hf.space
+   - 281+ cryptocurrency resources across 12 categories
+
+2. **Crypto DT Source** (Unified API)
+   - URL: https://crypto-dt-source.onrender.com
+   - Unified cryptocurrency data API v2.0.0 with AI models
+
+## 📋 Changes Made
+
+### 1. Client Services Created
+
+#### `/workspace/backend/services/crypto_api_clean_client.py`
+- Complete async client for Crypto API Clean
