Call the YouTube related videos API for JSON. 1 credit per call. Returns the videos YouTube suggests next to a video, equivalent to its Up next list. The video is identified by its URL or ID. ## Request Exactly one of `videoUrl` or `videoId` is required. A request that sets both, or none, fails with `invalidRequest`. ```typescript TypeScript icon="https://mintlify.s3.us-west-1.amazonaws.com/sirathic/images/icons/typescript.svg" theme={null} theme={null} import { Stophy } from "stophy"; const stophy = new Stophy({ apiKey: process.env.STOPHY_API_KEY }); const result = await stophy.youtube.related({ videoId: "p0fybvFyOlM" }); console.log(result.data.results); ``` ```python Python icon="python" theme={null} theme={null} from stophy import Stophy stophy = Stophy() # reads STOPHY_API_KEY result = stophy.youtube.related(video_id="p0fybvFyOlM") print(result["data"]["results"]) ``` ```bash cURL icon="terminal" theme={null} theme={null} curl -X POST https://api.stophy.dev/v1/youtube/related \ -H "Authorization: Bearer $STOPHY_API_KEY" \ -H "content-type: application/json" \ -d '{"videoId":"p0fybvFyOlM"}' ``` ```bash CLI icon="square-terminal" theme={null} theme={null} stophy youtube related --videoId p0fybvFyOlM ``` ## Response If successful, the response body contains the standard envelope. `data.results[]` contains the videos YouTube suggests next. The following example is a real response, truncated: each list shows one item and long strings are cut. ```json theme={null} { "success": true, "data": { "results": [ { "type": "video", "videoId": "ujkD4SxPKOI", "videoUrl": "https://www.youtube.com/watch?v=ujkD4SxPKOI", "title": "AI Just Crossed the Terrifying Line - Now What?", "channelId": "UCsXVk37bltHxD1rDPwtNM8Q", "channelName": "Kurzgesagt – In a Nutshell", "channelUrl": "https://www.youtube.com/channel/UCsXVk37bltHxD1rDPwtNM8Q", "channelUsername": "kurzgesagt", "durationSeconds": 1304, "views": 1200000, "thumbnailUrl": "https://i.ytimg.com/vi/ujkD4SxPKOI/hqdefault.jpg", "isShort": false, "isLive": false, "publishedAt": "2026-10-05T15:47:03.000Z" } ], "cursor": "CBoSDRILcDBmeWJ2RnlPbE0YACq8CTJzNkw2d3lHQndxREJ3b0Q4ajRBQ2c3Q1Bnc0k0dEc4NHBMOHdKeTZBUW9EOGo0QUNnM0NQZ29JaXVTTzV0bjA1ZlJ…" }, "creditsUsed": 1, "requestId": "2fe9dbad-fc48-4890-9751-0b24b596035b" } ``` | Field | Type | Description | | - | - | - | | `cursor` | string | The pagination token. Pass it as `cursor` to retrieve the next page. Omitted on the last page. | | `type` | string | The kind of item: `video`, `channel` or `playlist`. | | `publishedAt` | string (ISO 8601) | Approximate. YouTube lists show only how long ago a video was published. [YouTube video](/api-reference/endpoint/youtube-video) has the exact time. | | `durationSeconds` | integer | The duration, in seconds. | For every field, see the response schema on this page. ## Optional parameters | Parameter | Type | Description | | - | - | - | | `cursor` | string | The pagination token from the previous response. | ## Billing Each successful request consumes 1 credit, regardless of the number of items returned. Requests that fail, or that return no items, are not billed. ## Pagination Results are paginated. To retrieve the next page, pass the value of `data.cursor` as `cursor` in a subsequent request. A response that omits `cursor` is the last page. ## Related methods * [YouTube transcript](/api-reference/endpoint/youtube-transcript): Accepts `videoUrl`. Returns what a YouTube video says, from its captions. * [YouTube video](/api-reference/endpoint/youtube-video): Accepts `videoUrl`. Returns a video's stats, description, chapters and most replayed moments. * [YouTube comments](/api-reference/endpoint/youtube-comments): Accepts `videoUrl`. Returns a video's comments, or the replies to one comment. * [YouTube channel](/api-reference/endpoint/youtube-channel): Accepts `channelUrl`. Returns a channel's profile and one tab of videos, shorts, live, playlists, podcasts or posts. ## OpenAPI ````yaml api-reference/openapi.json POST /v1/youtube/related openapi: 3.1.0 info: title: Stophy API version: '1' description: >- Every endpoint is a POST that takes its input as a JSON object body. Unknown fields are rejected with 400. Responses leave out empty values: null, empty strings, empty objects and empty nested lists are not sent. x-credits is what one call costs. Every call costs the same, whatever it returns, unless an operation's description says it costs per 10 results, or per second of audio. Then x-credits is the lowest price and x-credits-max the most one call can cost. Where an operation takes limit, send it to return fewer results and pay for fewer. When a response has a cursor, send it back unchanged with the same input to get the next page. When it has a page, send the next page number. servers: - url: https://api.stophy.dev security: - apiKey: [] paths: /v1/youtube/related: post: summary: Get the videos YouTube suggests next to a video, like its Up next list description: Costs 1 credit per call.
