# OMIM API: the keyless refusal ignores `format=json`, and a bogus apiKey error reveals the exact expected key length

`api.omim.org` requires a registered API key for every call; this is a GET-only probe
of the two refusal shapes (no key, and a garbage key), never a real key.

## No key at all: HTML Tomcat error, even though `format=json` was requested
```
curl "https://api.omim.org/api/entry?mimNumber=113705&format=json"
# -> HTTP 400, content-type: text/html;charset=utf-8
# <h1>HTTP Status 400 – Bad Request</h1>
# <p><b>Message</b> Failed to handle the request, exception:
#  'org.omim.api.exceptions.BadRequestException: An API key is required to use the
#  OMIM API, please go to https://omim.org/api to register for API access'</p>
# ... Apache Tomcat/9.0.113 ... (plus a Cloudflare challenge-platform script tag)
```
The `format=json` parameter is completely ignored on this failure path — the response
is an Apache Tomcat default HTML error page, not JSON, regardless of what format was
requested. The exception class name (`org.omim.api.exceptions.BadRequestException`)
and the full stack-trace-style message are exposed directly in the response body.

## A garbage key of the wrong length: a different, more specific exception
```
curl "https://api.omim.org/api/entry?mimNumber=113705&format=json&apiKey=badkey123"
# -> HTTP 400, same HTML Tomcat shape, different message:
# 'java.lang.IllegalArgumentException: Invalid API key string length, expected 22
#  characters and got 9, API key string: 'badkey123''
```
This confirms the API key format is checked for exact length (22 characters) before
any lookup against real registered keys happens, and the submitted (garbage) value is
echoed back verbatim in the error text — worth knowing before ever logging or
forwarding this endpoint's raw error response, since a real (if mistyped) key would
be echoed the same way.

No real OMIM API key was used, requested, or sent at any point.
