# Quick Start Guide

This guide will help you quickly get started with using Storage Proofs. Follow these steps to submit your first Storage Proof request and access verified blockchain data.

## Proving Account Balance

### Step 1: Sign Up for an API Key

1. Visit the [Herodotus Dashboard](https://dashboard.herodotus.dev/login).
2. Register or log in using your in-browser wallet with Sign in with Ethereum.
3. Once logged in, access your API key from the dashboard.

### Step 2: Prepare Your Storage Proof Request

Construct a POST request to the Storage Proof API. Here's a basic example:

```
{
  "destinationChainId": "11155111",
  "fee": "0",
  "data": {
    "11155111": {
      "block:5150551": {
        "accounts": {
          "0x17C2D875CB397D813eAE817DaFD25807E348Df07": {
            "props": ["BALANCE"],
            "slots": []
          }
        }
      }
    }
  }
}
```

This request proves the balance of a specific account on the Ethereum Sepolia testnet.

### Step 3: Submit Your Request

Send a POST request to:

```
https://api.herodotus.cloud/submit-batch-query?apiKey=YOUR_API_KEY_HERE
```

Replace `YOUR_API_KEY_HERE` with your actual API key.

### Step 4: Check the Status

Use the returned `internalId` to check the status of your request:

```
GET https://api.herodotus.cloud/batch-query-status?apiKey=YOUR_API_KEY_HERE&batchQueryId=YOUR_INTERNAL_ID
```

### Step 5: Access Proven Data

Once the status is "DONE", you can access the proven data through the Facts Registry contract on the destination chain. For Sepolia testnet:

1. Go to the correct [Facts Registry contract on Etherscan](https://sepolia.etherscan.io/address/0x7Cb1C4a51575Dc4505D8a8Ea361fc07346E5BC02#readContract).
2. Use the `accountField` function to retrieve the proven data.

## Next Steps

* Explore the [full API documentation](https://api.herodotus.cloud/docs) for more advanced usage.
* Check out the Turbo interface for easier integration with smart contracts.
* Try out different types of proofs using the workflow examples.

Congratulations! You've now used Storage Proofs to verify blockchain data. As you become more familiar with the system, you can create more complex proofs and integrate them into your applications.
