For the latter, you don't have to provide this to AC beforehand, but you will have to provide it at check in. It makes it easier and faster if you provide it before checkin.
APIS information actually requires Name, DOB, Gender, Passport Info, and Destination Address (for non-US citizens/green card holders going to the US), while SecureFlight only requires Name, DOB, and Gender.
For airlines that do not have domestic flights within the US (eg. AC, BA, CX, SQ etc.), and all their flights involving the US involve crossing an international border, the APIS information collected also serves as the SecureFlight information.
By default, airlines that have lots of US domestic flights (eg. UA), will only collect SecureFlight data. Only when flights cross an international border will they request additional information (passport data, destination address details) - usually at the Online Check-In stage.
