In the general case:

i) if an upstream data source's API specifies as part of its terms and
conditions of use that no consuming application request more than 24
hours of data in a single API call; and

ii) a consuming application is asked to fetch n days of listings (n > 1); and

iii) said application makes a single API call, requesting the n days
of data in a single call, rather than 5 separate requests (day n, day
n+1, day n+2,...) the consuming application is not compliant with the
upstream Terms.

It does not matter if an application provides additional options that
*could* be used to request the data in accordance with the Terms and
Conditions. It does not matter if a developer does not agree with the
Terms of use.

If it is possible for an application to breach the Terms of its
upstream data source during normal use it needs to be updated to
ensure all possible use cases respect upstream's Terms of use.

Additionally, if Terms of use for a data source change over time, it
is a developer's responsibility to ensure the consuming application
stays compliant.

Thanks,
Nick
