to get your free moon, just call https://api.moon.supply/img?lat=&lon=
the Moon Clock Project provides a free API which will return a 320x320 black and white image of the moon for the provided latitude and longitude.
the API returns a base64 encoded string of a png.
by way of example, here's how you'd get the current moon for San Francisco, California
there are currently no planned changes for the moon supply API
there is also no service guarantee.
if you find a bug or build something using moon.supply's api, we'd love to hear about it. send us an email at firstname.lastname@example.org
coming soon: buy your own moon clock!
