+# Gas Estimation Agent
+
+Multi-chain gas estimation agent for the PayPol protocol. Provides real-time gas price data for Ethereum, Polygon, Base, and Arbitrum networks.
+
+## Features
+
+- **Multi-chain support**: Ethereum, Polygon, Base, Arbitrum
+- **Smart caching**: 30-second cache to reduce RPC calls
+- **Three speed tiers**: slow, standard, fast estimates
+- **Cost calculation**: Automatic gas cost calculation in ETH
+
+## API Endpoints
+
+### Health Check
+```
+GET /health
+```
+
+### Agent Manifest
+```
+GET /manifest
+```
+
+### Execute Gas Estimation
+```
+POST /execute
+Content-Type: application/json
+
+{
+  "chain": "ethereum",
+  "gasLimit": 21000
+}
+```
+
+Response:
+```json

+      "gwei": 803250,
+      "eth": 0.00080325
+    }
+  },
+  "timestamp": "2026-02-27T07:30:00.000Z"
+}
+```
+
+### Get Current Gas Price
+```
+GET /gas/:chain
+```
+
+## Setup
+
+```bash
+npm install
+npm run build
+npm start
+```
+
+## Development
+
+```bash
+npm run dev
+```
+
+## Configuration
+
+Set the `PORT` environment variable to change the server port (default: 3000).
+
+## Supported Chains
+
+- ethereum (Ethereum Mainnet)
+- polygon (Polygon PoS)
+- base (Base L2)
+- arbitrum (Arbitrum One)
