Status page docs offers endpoints which can be used only with API key. We also found a library which uses v2 endpoints. But it's mentioned here that v2 endpoints are deprecated. Also I haven't managed to find any docs about v2 endpoints.
For us it's more convenient to use v2 api since it doesn't require api key and doesn't have as strict limit restrictions as v1 api has. In addition to that v2 also seems more preferable because it's easier to make requests without need to proxy them like it seems necessary to do for v1 api.
Are permissions calls to v2 api limited to GET only requests? Are there any docs on v2 api? Is v2 api deprecated?
