<div class="moz-cite-prefix">Hi Geoffrey,<br>
<br>
as the Directions API is our commercial offering I would avoid the
mailing list :) (just guessing that this is spam probably for many
list members)<br>
<br>
And ask you to use the <a
href="https://github.com/graphhopper/directions-api">issue
tracker for the API</a> instead or contact us directly for
further discussion. <br>
<br>
We offer free accounts up to 500 credits per day which <a
href="https://github.com/graphhopper/directions-api/blob/master/FAQ.md#what-is-one-credit">would
allow you</a> one matrix with even only 30 locations per day. Of
course for your example we will offer you something more, just <a
href="https://graphhopper.com/#directions-api">sign up</a> and
let us discuss as we've already done similar with <a
href="http://ffwdmejs.org/">ffwdmejs.org</a>, osm.org, Gnome
Maps, ....<br>

it is more even for the car-only profile and without CH<br>

<br>
Yes, sure. You can use your optaplanner example key and ask people
to get their own<br>
<br>
Kind Regards,<br>

Hi Peter at all,<br>
<br>
I am planning to also use graphhopper's matrix API in
optaplanner-webexamples,<br>
to generate the distance matrix for a number of locations in a
VRP.<br>
<br>
But I worry about my example flooding your server (which would
make me a bad citizen).<br>
If I put no restrictions in it, and a user gives me a list n
locations, I am effectively asking for n² route distances....<br>
<br>
For this reason, Google Maps has quota's in place, but those were
really annoying when I generated the data for this post:<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://www.optaplanner.org/blog/2015/03/20/3BugsInTheUltimateAmericanRoadTrip.html">http://www.optaplanner.org/blog/2015/03/20/3BugsInTheUltimateAmericanRoadTrip.html</a><br>
because I needed 50 locations, which is almost 2500 routes and
they only allow 2500 routes per day<br>
(so I had one shot per day to get it right).<br>
<br>
Does GraphHopper have quota's in place?<br>
If not, on what maximum number of locations should I restrict?<br>
Note: I don't want to host my own GraphHopper server as part of
optaplanner-webexamples (because that would mean including 6GB of
world map data), so I 'd like to reach out to your service.<br>
I do expect users to copy-paste the optaplanner-webexamples, but I
'll put in a clear warning that they also shouldn't flood your
server (=> host their own server etc).<br>
Wdyt?<br>
<br>
With kind regards,<br>
