They're orthoganal, so what you suggest is in fact the status quo.
RIS, Route-Views, and PCH collect and archive routing information for

get the IP address but i dont get the AS number.

We have archives of much of that information

Any clues on how i can get the AS number?
If you just want this for one thing, not lots, you can just track it down

No. Wrong.
IP addresses are allocated to network providers, or to end-user
networks. The recipient of a block of IP addresses (by direct

asn.routeviews.org doesn't do longest-prefix matching, so you need a

which means host -t txt ip will return more than one record, yes?
Exactly.

We have
Basically, we get bulk data from the five RIRs, and try to parse
it into a structured database. For the ones like ARIN and LACNIC, that
are coming out of a similar relational database, it's not too difficult
work. For others, it's largely manual.
