​

Step 3: Make Your First API Call

Let’s make a simple API call to the Storage Proof API to prove an account’s balance:

curl -X POST https://api.herodotus.cloud/batch-query \
-H 'Content-Type: application/json' \
-H 'api-key: your-api-key-here' \
-d '{
  "destinationChainId": "11155111",
  "fee": "0",
  "data": {
    "11155111": {
      "block:5150551": {
        "accounts": {
          "0x17C2D875CB397D813eAE817DaFD25807E348Df07": {
            "props": ["BALANCE"],
            "slots": []
          }
        }
      }
    }
  }
}'

If successful, you’ll receive a response with an internal ID:

{
  "internalId": "01J2V235ABJY55JS2MY051ZJFJ"
}

The response will indicate the current status of your query:

{
  "queryStatus": "IN_PROGRESS"
}

​

Step 4: View query on Dashboard

You can use the returned internal ID on the dashboard to view the query in the explorer.
