+
+## API Endpoints
+
+### Mint NFT
+```http
+POST /api/mint
+Content-Type: application/json
+
+{
+  "prompt": "a beautiful sunset over mountains",
+  "userAddress": "0x..."
+}
+```
+
+### Get NFTs
+```http
+GET /api/nfts?page=1&limit=4
+```
+
+## Smart Contract
+
+The project uses an ERC721 smart contract deployed on BNB Smart Chain:
+
+```solidity
+// SPDX-License-Identifier: MIT
+pragma solidity ^0.8.20;
+
+import "@openzeppelin/contracts/token/ERC721/extensions/ERC721URIStorage.sol";
+import "@openzeppelin/contracts/access/Ownable.sol";
+
+contract AINFT is ERC721URIStorage, Ownable {
+    uint256 private _nextTokenId;
+
+    constructor(address initialOwner) ERC721("AI NFT", "AINFT") Ownable(initialOwner) {}
+
+    function safeMint(address to, string memory uri) public onlyOwner {
+        uint256 tokenId = _nextTokenId++;
+        _safeMint(to, tokenId);
+        _setTokenURI(tokenId, uri);
+    }
+}
+```
+
+## Architecture
+
+### Data Flow
+1. User inputs text prompt
+2. Frontend sends request to backend
+3. Backend generates image using Stability AI
+4. Image uploaded to IPFS via Pinata
+5. NFT metadata created and uploaded to IPFS
+6. Smart contract mints NFT with metadata URI
+7. Transaction hash returned to frontend
+
