Update handlers documentation

**Description**
Currently parsers lacks proper pagination support.

**Proposed solution**
Add configurable pagination with sensible defaults.

**Priority**: Low/Medium

No files, tests, or entry points are named. Start by locating the parser and handler implementations and checking how current responses are consumed; the work is done when pagination is configurable, has documented sensible defaults, and is covered by relevant tests.
