As I use the Alchemy API service on Bluemix, I see the daily-transaction-limit-exceeded message. How can I monitor my transaction usage to determine when I am approaching the limit?
Each API call typically equals many transactions. In the JSON response, you should see a transaction count returned for every API response that you receive from the server. However, you can determine the number of daily transactions that remain using the following query:curl -i http://access.alchemyapi.com/calls/info/GetAPIKeyInfo?apikey=<api_key>
Replace the <api_key> variable with your own API key.
In the XML that is returned, you will receive a count of your daily usage plus the transaction limit.
