Perhaps say
<title>MediaWiki API results</title>
instead of just
<title>MediaWiki API</title>
in response to queries.
Helps people looking in their browser histories, etc.
(P.S., help has a grammar problem:
Get information about all categories used in the [[Albert Einstein]]:
)
Hmmm, could make help have it's own different <title>... no, nevermind.
