Google Maps DIRECTIONS API

[amgdba]

I am testing a mapping solution and I have the following:

1. A list of location addresses.

2. A XSLT stylesheet (it actually works)

3. A well formed xml request to Google Maps Directions API

4. A FM solution that captures this data.

Everything works, so the problem is this;

Everytime I work working on this solution, it just up and stops after a little while and dies until a day or two has passed. Yes, I copied the URL for the XML into my browser and I get a result of "OVER QUERY LIMIT". Ok, I sign up for an API key (note that the DIRECTIONS API instructions page clearly states you don't need one, but anyways). I try again, nothing.

I don't understand why it is doing this because my little list of 146 locations is a far cry from the listed max of 2500 stated.

Does anybody have any thoughts or experience on this?
