Dune Analytics

Query live on-chain data via the Dune REST API. Pair with MoonPay to create and fund the wallets you analyze.

Setup

Get a Dune API Key

1. Sign up at https://dune.com
2. Go to Settings → API Keys → Create new key

export DUNE_API_KEY="your-api-key"

Base URL: https://api.dune.com/api/v1
Auth header: X-Dune-API-Key: $DUNE_API_KEY

---

Key Endpoints

Action	Method	Endpoint
Execute a saved query	POST	/query/{query_id}/execute
Get execution status + results	GET	/execution/{execution_id}/results
Execute raw SQL directly	POST	/sql/execute
Cancel execution	POST	/execution/{execution_id}/cancel
Get query definition	GET	/query/{query_id}

Common Workflows

Run a Saved Query

# 1. Execute
EXEC=$(curl -s -X POST "https://api.dune.com/api/v1/query/3237661/execute" \
  -H "X-Dune-API-Key: $DUNE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"performance": "medium"}')

EXEC_ID=$(echo $EXEC | jq -r '.execution_id')
echo "execution_id: $EXEC_ID"

# 2. Poll until complete
while true; do
  STATUS=$(curl -s "https://api.dune.com/api/v1/execution/$EXEC_ID/results" \
    -H "X-Dune-API-Key: $DUNE_API_KEY")
  STATE=$(echo $STATUS | jq -r '.state')
  echo "State: $STATE"
  if [[ "$STATE" == "QUERY_STATE_COMPLETED" || "$STATE" == "QUERY_STATE_FAILED" ]]; then
    echo $STATUS | jq '.result.rows[:5]'
    break
  fi
  sleep 3
done

Execute Raw DuneSQL

curl -s -X POST "https://api.dune.com/api/v1/sql/execute" \
  -H "X-Dune-API-Key: $DUNE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "sql": "SELECT block_time, hash, value/1e18 AS eth FROM ethereum.transactions WHERE lower(\"from\") = lower('0xYOUR_WALLET') ORDER BY block_time DESC LIMIT 20",
    "performance": "medium"
  }' | jq '.execution_id'

Query with Parameters

curl -s -X POST "https://api.dune.com/api/v1/query/3237661/execute" \
  -H "X-Dune-API-Key: $DUNE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query_parameters": {
      "wallet": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045",
      "days": 30
    },
    "performance": "medium"
  }' | jq '.execution_id'

Wallet Management with MoonPay

Use the MoonPay CLI (mp) to create and fund the wallets you analyze with Dune.

Create a Wallet to Monitor

mp wallet create --name "dune-agent-wallet"
mp wallet retrieve --wallet "dune-agent-wallet"
# Note your Ethereum address for Dune queries

Query Your MoonPay Wallet On-Chain

WALLET=$(mp wallet retrieve --wallet "dune-agent-wallet" --json | jq -r '.addresses.ethereum')

EXEC_ID=$(curl -s -X POST "https://api.dune.com/api/v1/sql/execute" \
  -H "X-Dune-API-Key: $DUNE_API_KEY" \
  -H "Content-Type: application/json" \
  -d "{\
    \"sql\": \"SELECT block_time, hash, value/1e18 AS eth, \\\"to\\\" FROM ethereum.transactions WHERE lower(\\\"from\\\") = lower('$WALLET') ORDER BY block_time DESC LIMIT 20\",\
    \"performance\": \"medium\"\
  }" | jq -r '.execution_id')

curl -s "https://api.dune.com/api/v1/execution/$EXEC_ID/results" \
  -H "X-Dune-API-Key: $DUNE_API_KEY" | jq '.result.rows'

Fund the Wallet

# Buy ETH for gas
mp buy --token eth_ethereum --amount 0.1 --wallet <your-eth-address> --email <email>

# Check balances
mp token balance list --wallet <your-eth-address> --chain ethereum

# Bridge to follow yields
mp token bridge \
  --from-wallet dune-agent-wallet --from-chain ethereum \
  --from-token 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 \
  --from-amount 500 \
  --to-chain polygon \
  --to-token 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174

Execution States

State	Meaning
QUERY_STATE_PENDING	Queued
QUERY_STATE_EXECUTING	Running
QUERY_STATE_COMPLETED	Results ready
QUERY_STATE_FAILED	Check error message
QUERY_STATE_CANCELLED	Cancelled

Security

• Never expose DUNE_API_KEY in logs or responses — redact before showing output
• Confirm with the user before running write operations (creating/updating saved queries)
