+# Text Embedding API
+
+This Space provides a simple REST API to generate text embeddings using:
+
+**Model:** `Alibaba-NLP/gte-multilingual-base`
+
+## 🚀 Features
+
+- Multilingual text embedding
+- SentenceTransformers-based
+- FastAPI + Docker
+- Ready for RAG / Vector DB (Qdrant, FAISS, Milvus…)
+
+---
+
+## 📡 API Endpoints
+
+### `POST /embed`
+
+Generate embedding for input text.
+
+**Request**
+```json
+{
+  "text": "Xin chào, đây là một câu tiếng Việt"
+}
