I don't have an application to submit at the moment, but can I apply the key first?
Don't register for a key until you need it.
See "How API Keys Work" for more about API keys.
Thanks Kevin, I got it. I don't want dummy application appears on app tab too. May 21, 2010 at 2:50
You don't need an API key until your app goes live. For small traffic amounts (under 300 requests/day) you can use the API without the key to test your app:
Do I need an API key?
A single IP can only make a limited number of requests per day to the API. This limit is determined at first request time, and is dependent upon the presence of an API key.
API daily limits:
No Key: 300
No Keylimit is meant to facilitate experimentation, not for deployed apps.
Requests with invalid or revoked keys are not completed, they are not stepped down to the
No Key limit.
If I run out 300 requests, should I change my IP address? :) May 20, 2010 at 6:45
But looks like this is the answer, make sense though. May 20, 2010 at 6:48
apptag from your question.
