Hi Zhan Zhaohua, I've seen nobody responded so I drop in.
I've worked a bit on integrit recently, I will try to
answer what I can.

No, and yes. No because integrit does not officially have
a documented api except for the command line utility.
Yes because and internal api is used by the i-ls and i-viewdb
utilities to access and stat files produced by integrit.
The code is clearly separated, and thus tailoring integrit
to your needs should be easy. This is still not documented
and subject to change though, so it depends on your needs.
The output format instead is clearly documented and will
remain consistent across releases.

You can better verify it by yourself.
integrit runtime execution speed and size is mostly
cdb's speed, which is rather conservative. Please see:

  http://cr.yp.to/cdb.html

Currently integrit grows up to 6mb of real (22mb virtual)
memory to scan appprox 250k files on linux. Each record
takes ~230bytes on the final db.

A C compiler and a posix system.
No external libraries are required.
