As of r52190 [1], API maxlag errors (the kind of error you get when you set &maxlag=2 and the maximum slave lag is higher than two seconds) return a HTTP 503 status code rather than a 200, for consistency with index.php (which does the same thing). The text of the response has not changed:
<api> <error code="maxlag" info="Waiting for 10.0.6.38: 1 seconds lagged" /> </api>
If this is a 503 error, can't we set an HTTP header with the retry delay? Otherwise this adds yet another complexity to error handling. Index.php sets "Retry-After" and "X-Database-Lag" headers when maxlag is exceeded, via wfMaxlagError().
