# Direct Stake API

### 📌 Introduction

For developers who prefer not to use React or wish to integrate minting functionality in a custom manner, The Vault offers a direct API endpoint at [https://direct.vaultapi.dev](https://direct.vaultapi.dev/). This API enables you to mint Liquid Staking Tokens (LSTs) by constructing transactions tailored to your application's requirements.

🔗 **GitHub Repository**: [The Vault LST Creator Widget](https://github.com/SolanaVault/lst-minter-widget)

### 🔗 API Endpoint

* **URL:** <https://direct.vaultapi.dev>

### ⚡ Required Query Parameters

To successfully create a transaction, the following parameters must be included in the request:

| Parameter         | Type   | Description                                        |
| ----------------- | ------ | -------------------------------------------------- |
| `mint`            | String | The mint address of the LST to be minted.          |
| `wallet_address`  | String | The wallet address initiating the minting process. |
| `amount`          | Number | The amount of tokens to be minted.                 |
| `current_balance` | Number | The current balance of the user's wallet.          |

### ⚙️ Optional Parameter

* **`target`** (String): Required only when minting vSOL, specifying the target address.

### 📊 API Response

Upon sending a valid request, the API returns a base64-encoded transaction (`transaction`). The user's wallet must sign this transaction and then broadcast it to the Solana network to complete the minting process.

### 🚀 Integration Steps

#### 1️⃣ Construct the API Request

Gather the required parameters (`mint`, `wallet_address`, `amount`, `current_balance`). If minting vSOL, also include the `target` parameter.

#### 2️⃣ Send the Request

Make a GET request to:

```bash
https://direct.vaultapi.dev
```

with the collected parameters.

#### 3️⃣ Handle the Response

Receive a base64-encoded transaction (`transaction`) from the API.

#### 4️⃣ Sign the Transaction

Prompt the user's wallet to sign the received transaction.

#### 5️⃣ Broadcast the Transaction

Submit the signed transaction to the Solana network for processing.

### 💡 Example API Call

You can test the API with the following example:

```bash
curl "https://direct.vaultapi.dev/stake?\
address=<Minter's wallet address>&\
mint=vSoLxydx6akxyMD9XEcPvGYNGq6Nn66oqVb3UkGkei7&\
amount=100000&\
balance=1000000"
```

If you run this, you will receive a transaction (`transaction`) that you can inspect and simulate by pasting it into the [Solana Transaction Inspector](https://explorer.solana.com/tx/inspector).
