There are, though, two potentially useful open data coordinate mapping
systems that can be used by the likes of OSM. One is Mapcode, the
other is Google's Open Location Code (aka Plus Codes). Both have the
advantage of not only being entirely free and open to use, but can
also be generated programmatically from a published algorithm - no
need to hook into an API, just run some code locally.
There is also the extended form of the venerable Maidenhead Locator System.
Ah, that's a new one on me. Looks a pretty simple algorithm, too. Thanks.
