Overview

What the Actor is good at#

The Actor is a batch job with billing attached. It suits work shaped like a job rather than a request:

  • One-off or scheduled exports where the output is a file or a dataset.
  • Runs where you want a hard spend cap enforced by the platform.
  • Work done by someone who should not hold an API key — the Console form is a validated UI.
  • Pipelines already built on Apify integrations, storage, and scheduling.

It charges per delivered row and needs no X login, no credentials, and no infrastructure of yours.

What the REST API is good at#

The API suits work shaped like a request rather than a job:

  • Fetching a single account's followers inside your own application flow.
  • Reacting to events, using signed webhooks for supported tweet and profile events.
  • Giving an AI agent tool access, through the MCP server's supported JSON or text operations.

The relevant endpoints are documented at:

A rule of thumb#

If the answer to "where does the data land" is a dataset, a spreadsheet, or a CRM import, use the Actor. If the answer is "inside my application, at request time", use the API.

One case sits between them: tracking how an audience changes. The Actor handles it by scheduling repeat runs and comparing stored datasets by profile id. It does not emit follower-list change events — Xquik monitors emit supported tweet and profile events instead. If you need push rather than poll for those events, that is the API's job.

The same pay-per-result model covers neighbouring data:
