responses. For how the main objects relate, read [Key concepts](/concepts); this
page complements it with short, alphabetical definitions.

## Terms

| Term                           | Definition                                                                                                                                                                                          |
| ------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Account**                    | A tracked Instagram or TikTok profile, identified by its `platform` (`instagram` or `tiktok`) and `username`. See [Key concepts](/concepts).                                                        |
| **Account video**              | A video discovered automatically from a tracked account's feed. You don't add these — they appear as the account is refreshed. Read via `/v2/account-videos`. See [Key concepts](/concepts).        |
| **API key**                    | The credential you authenticate with, scoped to a single [organization](/concepts). Create and manage keys at [API keys](/dashboard/api-keys); see [Authentication](/api-reference/authentication). |
| **Bearer token**               | How you present your API key on a request: `Authorization: Bearer YOUR_API_KEY`. See [Authentication](/api-reference/authentication).                                                               |
| **Creator**                    | A grouping of one or more accounts that you define — for example, one person's Instagram and TikTok profiles. Metrics roll up from the linked accounts. See [Key concepts](/concepts).              |
| **Cursor**                     | An opaque token that points to the next page of a collection. Pass the previous response's `next_cursor` back as the `cursor` query param. See [Pagination](/api-reference/pagination).             |
| **Engagement rate**            | `(likes + comments + shares) / views`, expressed as a percentage. One of the core analytics metrics. See [Key concepts](/concepts).                                                                 |
| **Individual video**           | A video you add yourself by URL, shortcode, or ID — even if you don't track the posting account. Read and managed via `/v2/videos`. See [Key concepts](/concepts).                                  |
| **Organization**               | Your workspace. Every account, creator, video, API key, and metric belongs to exactly one organization, and a key only ever returns that organization's data. See [Key concepts](/concepts).        |
| **Pagination**                 | Walking a collection one page at a time using `limit` and a `cursor`, stopping when `has_next` is `false`. See [Pagination](/api-reference/pagination).                                             |
| **Period / window**            | The span a metric is computed over — for example 7, 30, or 90 days, or a custom date range. See [Key concepts](/concepts).                                                                          |
| **Problem details (RFC 9457)** | The `application/problem+json` error format the API returns, with `type`, `title`, `status`, `detail`, `code`, and `instance`. See [Errors](/api-reference/errors).                                 |
| **Rate limit**                 | The per-key cap on how many requests you may make in a window, surfaced via `X-RateLimit-*` headers. See [Rate limits](/api-reference/rate-limits) and [Limits & quotas](/limits-and-quotas).       |
| **Time series**                | A daily series of a metric over a window that you can chart, as opposed to a single windowed total. See [Key concepts](/concepts) and [Data freshness](/data-freshness).                            |
| **Tracking**                   | Adding an account or video so CreatorAudit refreshes it on a schedule. Newly tracked resources begin populating as they're scraped. See [Data freshness](/data-freshness).                          |
| **`X-Request-ID`**             | A correlation id returned on every response. Include it when you contact [Support](/support) so we can trace the exact request. See [Errors](/api-reference/errors).                                |
