Step 3: Make Your First API Call

Submit a Storage Proof request via Mission Control to prove an account’s balance:

curl -X POST https://mission-control.api.herodotus.cloud/submit-request \
  -H 'Content-Type: application/json' \
  -H 'api-key: your-api-key-here' \
  -d '{
    "destination_chain_id": "11155111",
    "data": {
      "11155111": {
        "block:5150551": {
          "accounts": {
            "0x17C2D875CB397D813eAE817DaFD25807E348Df07": {
              "props": ["BALANCE"]
            }
          }

  }'

If successful, you’ll receive a request ID:
