I use the open souce platform Home Assistant to automate my house, including using the open source platform Music Assistant within it to select audio sources and distribute them to rooms. Dashboards on wall-mounted tablets and on phones provide the interface to control and monitor the system. With a REST API, folks like me could have Home Assistant request our concert statistics (and/or community statistics) to display as songs or artists are played in the system. This could be a good starting point for an API, at least, since it would require only a GET function (no need to develop server-side updating functionality for this).
That's a feature I'd pay for!

This would be great. With a concertarchives.org REST-ful API users would have a handful great opportunities:
- artist could automate to list their past and upcoming shows through it on their own websites
- labels/booking agencies could use such a standardized API to upload tourdates of all their artists to concertarchives.org
- concert photographers can use it to upload and add pictures to specific concerts
- concertarchives would be the single source for all concerts and through the API everyone can use and list the data, avoiding redundant datasources

This would open up so many possibilities! I have some project ideas, but they need an API to get the concerts a user has attended. I really hope this can be implemented one day

this idea would be very helpful!
