+# 🚀 rpc-check
+
+A simple Bun-powered server to check the availability of Cosmos-style RPC endpoints via JSON-RPC `status` requests.
+
+## 📦 Install dependencies
+
+```bash
+bun install
+```
+
+## ▶️ Run the server
+
+```bash
+bun run start
+```
+
+This will start an Express server (default port: `3344`) with a `/rpc-check` POST endpoint.
+
+## 📮 API Usage
+
+**Endpoint:** `POST /rpc-check`
+**Content-Type:** `application/json`
+
+### Request body:
+
+```json
+{
+  "chains": ["namada"]
+}
+```
+
+### Response:
+
+```json
+{
+    "namada": [
+        {
+            "chain": "namada",
+            "url": "https://rpc.namada.validatus.com",
+            "latency": 710,
+            "status": "OK"
+        },
+        {
+            "chain": "namada",
+            "url": "https://namada.itudou.xyz",
+            "latency": 718,
+            "status": "OK"
+        },
+        {
+            "chain": "namada",
+            "url": "https://rpc.namada.stakepool.dev.br",
+            "latency": null,
+            "status": "FAIL",
+            "message": "timeout of 5000ms exceeded"
+        }
+    ]
+}
+```
+
+## 🛠 Built with
+
+* [Bun](https://bun.sh) v1.2.11 — Fast all-in-one JS runtime
+* Express — For routing and JSON handling
+* Axios — For sending JSON-RPC requests
+* CORS — Enabled for all origins
+
+---
+
+Let me know if bạn cần thêm hướng dẫn Docker hoặc ví dụ cURL test nhé.
