Subject | re:st: geocode command and google query limit |
Date | Mon, 06 Feb 2012 07:36:25 -0600 |
Having worked with Google's Geocode API before.... 1) Anonymous people (without previous violations against them) get ~2000 queries per day (sliding window). You can get a non-anonymous account which will let you query more, but unless you are a non-profit or educator, you will need to pay $. (Not that expensive really, and if the service is that useful to you why shouldn't you pay for it???) 2) Yes, google takes your past into account. Wait a few days and the limit should climb back up to ~2000/day 3) No. ruediger.vollmeier@googlemail.com wrote: > Dear Stata users, > > I ve used the -geocode- command/.ado to locate institutions using the > fulladdress option (using number, street, city, country information). > However, for a high percentage of requests I made I got the error code > 620 (Google query limit reached).
