Reddit Subreddit Details Scraper

The Actor reads a subreddit's public record by name and saves a single structured row: the community's id, display name, description, creation date, weekly activity figures, and its full numbered rules list with each rule's expanded text. One run describes one community. No Reddit account, application, or API credential is involved.

Accepted input

Field	Required	Default	Notes
subreddit	yes	—	A bare name (technology), a prefixed name (r/technology), or a copied reddit.com link. A link is reduced to the community it names.

{
  "subreddit": "r/technology"
}

Response fields

The saved record carries id, fullname, name, display_name, prefixed_name, url, description, weekly_active_users, weekly_contributions, created_at, and rules.

{
  "id": "2qh16",
  "fullname": "t5_2qh16",
  "name": "technology",
  "display_name": "/r/Technology",
  "prefixed_name": "r/technology",
  "url": "https://www.reddit.com/r/technology/",
  "description": "Subreddit dedicated to the news and discussions about the creation and use of technology.",
  "weekly_active_users": 4305645,
  "weekly_contributions": 3184,
  "created_at": "2008-01-25T00:00:00.000Z",
  "rules": [
    {
      "number": 1,
      "title": "Submissions must be about technology",
      "description": "Submissions must be primarily news and developments relating to technology."
    }
  ]
}

name is the community's name as it appears in an address, and display_name is the same name as its moderators capitalise it, which is not always identical. rules is a list rather than a count: each entry carries the rule's number, its title, and the full body text Reddit shows when the rule is expanded, which is where the substance of a rule normally is.

There is no subscriber count, and none is invented

weekly_active_users is an activity figure and it is not the community's membership. It comes back far above member totals — a community whose membership is in the millions can report an activity figure in the millions too, and the two numbers are not the same measurement. Reddit does not expose a member total on any surface reachable without an account, so this Actor publishes none rather than renaming activity into membership. A subscribers column filled from this figure would answer the question wrongly and nobody downstream would find out.

weekly_contributions is the number of posts and comments Reddit reports in the community over the past week, and is a genuine activity figure in the same family.

Failures and partial results

A subreddit value that cannot be reduced to a community name is rejected before any request is made, with a message naming what was received. A community that does not exist ends the run cleanly with nothing saved rather than failing: the source does not distinguish an unknown name from an empty answer, so reporting a failure would be a claim the run cannot support.

Fields absent from the source are returned as null rather than omitted, so the column set is the same in every record, and rules is an empty list for a community that publishes none.

Cost

Charging is per community record saved to the dataset, plus the platform's one-off Actor start event. One run saves one row, and the rate reflects a whole run's work going into that row. A run that saves nothing is charged for nothing beyond the start event.

Reading many communities means many runs. There is no batch input here, deliberately: a run reads one community and the run either produced that community's record or it did not, which is a distinction a batch would blur.
