RFC9457: problem details for HTTP APIs

There are currently no standard ways for API to communicate there domain specific error where HTTP status is not enough. This RFC hopes to remedy that with a proposed schema for error response. I think it’s a good proposal, it give enough feedback and it’s flexibility enough to work in most API. The one thing I really like is that it forces you to document your API’s specific errors because a link to documentation about the error is included in the schema.
