Influencer Audit checks a creator across Instagram, TikTok, YouTube and X and returns one record per creator: an audit block per platform (followers, engagement rate, posting frequency, average views, likes and comments, top posts, hashtags, posting consistency), a cross-platform summary (total audience, follower-weighted engagement, largest and best-performing platform, posts per week, last activity) and the contacts the creator publishes in bios and link-in-bio pages. For agencies vetting creators, brands planning campaigns and creator marketplaces; $0.013 per platform audited + $0.005 per creator.

## Price per delivered record

| Event | Price | Per 1,000 | Charged for |
| --- | --- | --- | --- |
| Platform audit (`platform-audit`) | $0.013 | $13 / 1,000 | Charged once per platform (Instagram, TikTok, YouTube or X) whose full audit was delivered: the profile plus engagement statistics over its latest posts. |
| Creator summary (`creator-summary`) | $0.005 | $5 / 1,000 | Charged once per creator record with at least one platform delivered: total audience, weighted engagement, best platform, posting consistency and the contacts published in bios. |

Pay-per-event, USD, billed by Apify; no platform usage charge. Only records with status `ok` are charged. Cap a run with `maxTotalChargeUsd`. Apify free plan: up to 5 per run.

Example prompt: Audit the creator NASA on Instagram (nasa) and YouTube (@NASA): followers, engagement rate and posting frequency per platform, plus the combined audience and the best platform.

## Input

List the creators to audit, each with the profiles you want audited. Every creator becomes one dataset record with one audit block per platform, a cross-platform summary and the contacts the creator publishes.

| Field | Type | Default | Meaning |
| --- | --- | --- | --- |
| `creators` (required) | array | — | Creators: One entry per creator: an object with instagram, tiktok, youtube and/or x (handle or profile URL) plus an optional name, e.g. {"name": "NASA", "instagram": "nasa", "youtube": "@NASA"}; or a string of profile URLs / platform:handle tokens (ig:, tiktok:, yt:, x:) separated by spaces. Each platform listed is audited and charged once. Accounts on the Apify free plan can process up to 5 creators per run. |
| `scanLinkInBio` | boolean | `true` | Read linked pages for contacts: Read up to 3 link-in-bio pages or websites linked from the bios (one page each) for the e-mails, phone numbers and social profiles they list. Free. |
| `includePosts` | boolean | `false` | Include sampled posts: Add the sampled posts or videos of each platform (in the platform's own format) under platforms.<platform>.posts. Larger records. |
| `maxCreators` | integer | `100` | Max creators: Safety cap on creators processed in this run; further ones are ignored and counted in the OUTPUT record. |
| `concurrency` | integer | `2` | Concurrency: Creators processed in parallel (their platforms always run in parallel). |
| `itemTimeoutSecs` | integer | `360` | Timeout per creator (seconds): A creator still being fetched after this long is stopped and not charged. |
| `includeRaw` | boolean | `false` | Include raw upstream data: Attach each platform's raw upstream payloads under raw (much larger records). |

Example input:

```json
{
  "creators": [
    {
      "name": "NASA",
      "instagram": "nasa",
      "youtube": "@NASA"
    }
  ]
}
```

## Output

One record per input item with `status` (`ok` is charged; `not_found`, `error`, `skipped_*` are free) and `charged`. The run stores an `OUTPUT` summary record.

| Field | Type | Meaning |

| `input` | string | object | Input: The creator as processed: { name?, instagram?, tiktok?, youtube?, x? }. |
| `status` | string | Status: ok (at least one platform delivered; creator-summary charged) \| not_found (no profile exists) \| error \| skipped_invalid \| skipped_budget \| skipped_free_plan \| skipped_unmetered |
| `charged` | boolean | Charged: Whether this record incurred a pay-per-event charge. |
| `chargedEvent` | string | Charged event: creator-summary when the record was charged; the platform-audit events are counted in platformAuditsCharged and flagged per platform (platforms.<platform>.charged). |
| `chargedCount` | integer | Events charged: Events actually charged when the charge came back short of the requested count (present only then; a warning explains it). |
| `source` | string | Source: Upstream data sources (ScrapeCreators for Instagram, TikTok and YouTube; TwitterAPI.io for X). |
| `fetchedAt` | string | Fetched at: ISO timestamp. |
| `error` | object | Error: { code, message, provider?, status? } when status is not ok. Codes set by the runtime: budget_exhausted, free_plan_limit, unmetered, aborted, charge_failed, record_too_large, invalid_record, dataset_push_failed; upstream codes: auth, insufficient_credits, rate_limit, timeout, network, server, client, invalid_response, not_found. |
| `warnings` | array | Warnings: Notes about this record, e.g. a charge that came back short. |

| `totalPostsPerWeek` | number | null | Posts per week: Posting frequency summed over the platforms. |
| `consistencyScore` | integer | null | Consistency (0–100): Mean posting-regularity score of the platforms: 100 = evenly spaced posts, about 50 = random, 0 = bursts. |

## FAQ

**How is the engagement rate calculated?**

Per platform, from the latest posts: average interactions per post divided by followers, in percent (Instagram: likes + comments; TikTok: likes + comments + shares; X: likes + reposts + replies). YouTube's video list has no like counts, so YouTube reports views per subscriber instead. The summary weights each platform's rate by its followers.

**Which contacts are returned?**

Only what the creator publishes: e-mail addresses written in the bios, the websites and link-in-bio pages linked from the profiles, and the e-mails, phone numbers and social profiles those linked pages list. Nothing is guessed or looked up elsewhere.

**What if one platform fails or the account is private?**

The other platforms are still audited. A private or empty account is included with its profile only and is not charged; an unknown handle or a failed platform shows its error in `platforms.<platform>` and is not charged.
