Example Requests

Basic Status Check

curl "https://tachyon.rath.fi/api/tx?id=68fa3450539a3c9d28bbca33" \
  -H "api-key: YOUR_API_KEY"

Check Multiple Transactions

You can check multiple transactions by making separate requests:

#!/bin/bash

TX_IDS=("68fa3450539a3c9d28bbca33" "68fa3450539a3c9d28bbca34" "68fa3450539a3c9d28bbca35")

for tx_id in "${TX_IDS[@]}"; do
  echo "Checking status for transaction: $tx_id"
  curl "https://tachyon.rath.fi/api/tx?id=$tx_id" \
    -H "api-key: YOUR_API_KEY"
  echo ""
done

With jq for Formatted Output

curl "https://tachyon.rath.fi/api/tx?id=68fa3450539a3c9d28bbca33" \
  -H "api-key: YOUR_API_KEY" | jq '{
    id: .data.id,
    status: .data.status,
    executionHash: .data.executionTxHash,
    cost: .data.costUSD,
    latency: .data.latency
  }'

Example Output:

}

Understanding Costs and Charging

costUSD: Shows the estimated or actual transaction cost
isAccountCharged:
- false: Account not yet charged (transaction pending or failed)
- true: Account has been charged (transaction executed successfully)
Estimated vs Actual Cost: Before execution, costUSD shows the estimate. After execution, it shows the actual cost.

Use Cases

Transaction Monitoring

Check transaction status periodically to update your UI:

# Check status every 5 seconds
while true; do
  status=$(curl -s "https://tachyon.rath.fi/api/tx?id=68fa3450539a3c9d28bbca33" \
    -H "api-key: YOUR_API_KEY" | jq -r '.data.status')
  echo "Current status: $status"
  
  if [ "$status" = "EXECUTED" ] || [ "$status" = "FAILED" ]; then
    break
  fi
  
  sleep 5
done

Cost Tracking

Retrieve cost information for accounting:

curl "https://tachyon.rath.fi/api/tx?id=68fa3450539a3c9d28bbca33" \
  -H "api-key: YOUR_API_KEY" | jq '{
    transactionId: .data.id,
    cost: .data.costUSD,
    charged: .data.isAccountCharged,
    timestamp: .data.timestamp
  }'

Error Handling

Check for errors and retry logic:

response=$(curl -s "https://tachyon.rath.fi/api/tx?id=68fa3450539a3c9d28bbca33" \
  -H "api-key: YOUR_API_KEY")

status=$(echo $response | jq -r '.data.status')
error=$(echo $response | jq -r '.data.error')

if [ "$status" = "FAILED" ]; then
  echo "Transaction failed: $error"
  # Implement retry or notification logic
elif [ "$status" = "NEEDS_TO_BE_RETRIED" ]; then
  echo "Transaction will be retried automatically"
fi
