Nested arrays and media references stay in their parent record. Downloading source media files is not part of this Actor.

Every top-level output field appears in these complete examples. The success example is normalized from a public response. Long strings and arrays are shortened here; the Actor keeps the complete available values. Values are a snapshot and can change. Nested arrays remain inside their parent result.

A failed row preserves input, sets status to failed, and sets every other top-level field to null. The run log records the reason. Optional successful fields can be null or empty when Niconico does not supply them. Object fields are exposed through useful columns in the single Users view; arrays are not expanded into extra result rows.

Input requirements and pagination settings ⚙️

Parameter	Type	Required	Default	Rules
inputList	array of strings	Yes	None	Enter positive numeric Niconico user IDs or public user URLs. A user video or mylist tab URL also identifies its user. At least 1 item.

Enter positive numeric Niconico user IDs or public user URLs. A user video or mylist tab URL also identifies its user.

Examples of supported inputs: https://www.nicovideo.jp/user/1.

Duplicate normalized inputs are processed once. Within the collection for one source input, repeated records are removed while distinct interactions or objects remain separate. The same object returned for different source inputs retains its source relationship.

There is no result-page setting. Each unique target is looked up individually, and nested fields remain within that result row.

Pricing and saved-result behavior 💰

Check the Actor’s Pricing tab for the active pricing model and current rate. Store settings can change, so this README does not claim a fixed price or runtime.

Under dataset-item pricing:

• Each successful result represents one user for its source input.
• An invalid or unavailable input, an input with no accessible results, or an exhausted request can produce a failed row.
• Retry attempts and supporting requests do not create extra dataset rows by themselves.
• Nested media, profile information and other arrays remain part of their parent row.
• A normal empty continuation after earlier successes creates no additional row.
• Saved failed rows are not assumed to be free; check their treatment in the active pricing configuration.

More inputs can produce more saved rows. Start with a small run and check actual usage before increasing the workload.

Niconico users API 🔌

Replace $ACTOR_ID with the identifier shown in this Actor’s API tab and $APIFY_TOKEN with your Apify token.

curl -X POST "https://api.apify.com/v2/acts/$ACTOR_ID/runs?token=$APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"inputList":["https://www.nicovideo.jp/user/1"]}'

Download the dataset in JSON, CSV, Excel or other formats available in the Console, or retrieve it through the Apify API. Use schedules, webhooks and Apify integrations to connect results to Google Sheets, Make, Zapier, cloud storage or your own application. These connections are configured separately by the user.

Reliability, retries, and public-data limits ⚠️

Collection uses pure HTTP with up to five concurrent requests. Invalid syntax and confirmed missing, removed or unavailable targets stop without unnecessary retries. Temporary network or proxy failures, timeouts, blocking responses, malformed data, throttling and server errors allow up to five total attempts per request.

Successful earlier pages remain saved if a later request fails. A normal end after saved results is not retried. An input with no accessible results can receive a failed row; that alone does not prove that its underlying source does not exist. An exhausted later request can add a failed row while preserving previous output.

Follower and following counts are summary metrics, not lists of accounts. Account level and experience are raw profile metrics; no audience estimates are inferred.

Niconico controls public availability, ranking and optional fields. Result counts can be affected by duplicates, removed content and changes during a run. A page budget is a collection limit, not a promise of exhaustive coverage.

An invalid string within a valid input list does not stop other inputs. Invalid overall configuration, such as a non-string list item or a wrong page-count type, exits before source requests. Startup failures, unavailable dataset storage or an unrecoverable result-save error can still stop the whole run. A failed save is not retried as a new scraping request.

Frequently asked questions ❓

What does one Niconico User Details Scraper result represent?

Each successful row represents one user. The source input is retained, and nested fields stay in the same row.

Which source limits apply?

Follower and following counts are summary metrics, not lists of accounts. Account level and experience are raw profile metrics; no audience estimates are inferred.

Does it download media files?

No. Where available, the Actor returns media URLs and metadata within the result row.

Does it require a Niconico account or personal cookies?

No. You do not need to provide a Niconico account, password or personal session cookie. Collection uses HTTP without opening a browser.

What happens to invalid or unavailable inputs?

Invalid individual inputs are recorded as failed without a source request. Confirmed missing or unavailable targets stop without unnecessary retries. Temporary failures allow up to five total attempts per request; other inputs and earlier saved results remain available.

Can I export results or run the same input again?

Yes. Export the default dataset or retrieve it through the Apify API. You can create an Apify schedule and connect completed runs to your own workflow.
