[GraphHopper] Quota's / flooding the Graphhopper matrix API service (being a good citizen)

[Peter]

Hi Geoffrey,

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)

And ask you to use the issue tracker for the API
<https://github.com/graphhopper/directions-api> instead or contact us
directly for further discussion.

We offer free accounts up to 500 credits per day which would allow you
<https://github.com/graphhopper/directions-api/blob/master/FAQ.md#what-is-one-credit>
one matrix with even only 30 locations per day. Of course for your
example we will offer you something more, just sign up
<https://graphhopper.com/#directions-api> and let us discuss as we've
already done similar with ffwdmejs.org <http://ffwdmejs.org/>, osm.org,
Gnome Maps, ....

get their own

Kind Regards,
