List custom fan lists

The creator's custom fan lists. Their ids are what you pass to listIds on GET /accounts/{of_user_id}/chats to filter the conversation list.

GET
/accounts/{of_user_id}/lists

The creator's custom fan lists. Their ids are what you pass to listIds on GET /accounts/{of_user_id}/chats to filter the conversation list.

⚠️ The upstream endpoint for this is unconfirmed: it has never been captured from a live account. This route probes the plausible paths and, if none answer, returns code: endpoint_unconfirmed rather than an empty list — so you never mistake "we could not find the endpoint" for "this creator has no lists". Treat a successful response as usable and an endpoint_unconfirmed one as unimplemented.

Fansly only.
