I prefer simplicity and using the first example but I’d be happy to hear other options. Here’s a few examples:

HTTP/1.1 403 POST /endpoint
{ "message": "Unauthorized access" }

HTTP/1.1 403 POST /endpoint
Unauthorized access (no json)

HTTP/1.1 403 POST /endpoint
{ "error": "Unauthorized access" }

HTTP/1.1 403 POST /endpoint
{
  "code": "UNAUTHORIZED",
  "message": "Unauthorized access",
}

HTTP/1.1 200 (🤡) POST /endpoint
{
  "error": true,
  "message": "Unauthorized access",
}

HTTP/1.1 403 POST /endpoint
{
  "status": 403,
  "code": "UNAUTHORIZED",
  "message": "Unauthorized access",
}

Or your own example.

    There are competing interests here: normal consumers and script kiddies. If I build an API that follows good design, RFCs, pretty specs, all of that, my normal users have a very good time. Since script kiddies brute force off examples from those areas, so do they. If I return 200s for everything without a response body unless authenticated and doing something legit, I can defeat a huge majority of script kiddies (really leaving denial of service). When I worked in video games and healthcare, this was a very good idea to do because an educated API consumer and a sufficiently advanced attacker both have no trouble while the very small amount of gate keeping locks out a ton of annoying traffic. Outside of these high traffic domains, normal design is usually fine unless you catch someone’s attention.
