When to use the YouTube Video Related API
Use it to map what YouTube recommends alongside a video, for competitor or content research; include=engagement adds likes, comments and exact views.
From the API reference
Returns the videos YouTube lists next to a video (its "up next" list), usually 11 or 12, in the order YouTube shows them. Each row carries the video id, URL, title, thumbnail, duration, view count and channel name, and the channel id when YouTube gives one. The list is what YouTube shows a signed-out viewer at the moment of the call, so it changes between calls. VIEWS are YouTube's rounded figure ("2.5B" is 2,500,000,000); send include=engagement for exact counts. With language, YouTube writes the labels in that language ("416 mil") and they are read at the same rounding. DATES: the list only labels each video ("16y ago"), so by default every row is joined to the per-video lookup for its exact publish second and its channel, at no extra credit (one lookup per page); with exact_dates=false no lookup runs and post.published_at is null. post.author.username is the channel's @handle, or null for a channel that has none (include=channel fills it where it exists). Send include=engagement for likes and comments, and include=channel for the channel's subscriber count and avatar. TITLES: the free lookup swaps a machine-translated listing title for the creator's own; a title not swapped carries post.ext.title_maybe_translated: true. Accepts a watch, youtu.be or Shorts URL. A video that does not exist is a 404 and is not charged.

What can you do with the Video Related API?
The Video Related endpoint gives you structured YouTube data with computed fields in a single request. No scraping infrastructure to build or maintain.
Example Request
# GET /v1/youtube/video/related: Metered: holds 1 credit per call up front and refunds what the call does not use. Cache hits are free and failed calls are refunded.
# Check the price first for 0 credits: add dry_run=1 to the query. Nothing is fetched or charged.
# --max-time 12: this endpoint's measured p99 latency x 1.5.
# --retry 3: retries timeouts, 429 and 5xx, honoring Retry-After.
# -o response.json keeps only the final attempt's body.
# One Idempotency-Key per request, reused on every retry, so a retried call is never charged twice.

if (body) console.log(body.data);Parameters
| Parameter | Required | Description |
|---|---|---|
| url | Yes | Full URL of the YouTube video or Short |
| language | No | Preferred language for the listing (mapped to Accept-Language; not guaranteed due to YouTube localization behavior). 2 letter language code, ie 'en', 'es', 'fr' etc. |
| include | No | Set to `engagement`, `channel`, or both (`engagement,channel`) to fill more of every row in this one call. `engagement` fills `post.engagement.views`, `.likes` and `.comments`, `post.content.duration_seconds`, `post.ext.channel_id` and `post.author.display_name` where the row lacks them, and replaces a date derived from a label such as "4 months ago" with the exact publish time (removing `post.ext.published_precision`). `channel` puts the channel's subscriber count on `post.ext.author_followers` (YouTube's own figure, which it rounds to three significant figures above 1,000) and fills the channel's `post.author.display_name`, `.avatar_url` and `.username` where missing. It also adds the country the channel's owner set, as an ISO 3166-1 alpha-2 code on `post.ext.author_country` (null when the channel sets none). Send both to cover rows that arrive without a channel id: the video join supplies it and the channel join then uses it. Each join costs 1 credit per distinct video or channel it filled, and never more than 5 per 50; ids that could not be filled are refunded. Each join adds 0.2 to 0.7 seconds on a fresh page (one lookup per 50 ids, never more than 8 seconds). Read `data.hydration` for the rows, lookups, credits held and kept, and the time. |
| exact_dates | No | Exact publish dates are on by default and free. A row whose date the upstream derived from a relative label such as "4 months ago" (measured up to four months off) is joined to the per-video lookup for its exact publish second, at no extra credit: one lookup per page (two on a page past 50 rows, side by side), adding about 0.2 to 0.7 seconds (never more than 3). The same lookup swaps the listing title, often YouTube's English machine translation, for the creator's own, and `computed.language` follows it; a title not swapped carries `post.ext.title_maybe_translated: true`. Set to `false` to skip the lookup: rows then carry the supplier's date estimate (a day-granular or coarser label truncated to midnight UTC), marked by `post.ext.published_precision` and `post.ext.published_label`, and the listing title, marked by `post.ext.title_maybe_translated`. A row the lookup could not resolve keeps those values and markers, and `_warnings` carries `exact_dates_partial` (some rows) or `exact_dates_unavailable` (none); on `channel/videos`, whose dates are already exact, the warnings are `original_titles_partial` and `original_titles_unavailable`. (true | false) |
| since | No | Only rows published on or after this date: YYYY-MM-DD (midnight UTC) or an ISO 8601 timestamp. Rows older than it are left off each page. This list is not in date order, so the walk does not stop at the date: keep following `next_cursor`, and each page costs what a page costs even when every row on it is filtered out. A row with no date is kept. `published_after`, `start_date`, `from_date`, `publish_time` (`yesterday`, `this-week`, `this-month`, `last-3-months`, `last-6-months`) and `max_age_days` are accepted and applied as `since`. |
| until | No | Only rows published on or before this date: YYYY-MM-DD (that whole UTC day is included) or an ISO 8601 timestamp. Newer rows are left off each page and the walk does not stop, so older pages follow. A row with no date is kept. `published_before`, `end_date` and `to_date` are accepted and applied as `until`. |
