Minor Planet Center
Asterank's Minor Planet Center proxy exposes the Minor Planet Center's orbital-element database for asteroids and other minor planets as simple keyless JSON queries, layered under Asterank's own asteroid-mining economics project. It's a free hobby service built on data sourced from the MPC and NASA JPL rather than an official IAU/MPC API. A live query against /api/mpc now succeeds over HTTPS as well as HTTP, so the stored url and https flag are corrected to the secure endpoint.
