`url` and possibly `max_toot_chars` are missing from `Instance` entity
When I inspected Instance entity using this endpoint GET /api/v2/instance for mastodon.social instance, I noticed that the url attribute is missing from the Instance entity documentation. The documentation does list message attribute but not for url. Currently the JSON response is null for url key.
As for max_toot_chars attribute, I only notice this peculiar attribute for todon.nl instance. As far as I can tell, this instance is running the official Mastodon instance. I don't get the impression that it is running a fork or some derivatives but I could be wrong. This key value matches max_characters value.
max_toot_chars is an unsupported extension, todon.nl likely has a local set of changes.
Could you please explain about extensions? It's the first time that I am hearing it. What do you mean by local set of changes? Is todon.nl not running an official Mastodon instance?
Mastodon does not allow changing the character limit away from the default 500 characters without modification. toot.nl allows 1312 characters, so they have made local changes to their installation. The max_toot_chars attribute is most likely from those changes.
