youtube.trending - Onekey docs

beta 2 credits may need a pack

Most popular YouTube videos in a region.

GET /v1/youtube/trending

What you get#

A list of YouTube results in Onekey's unified shape, in data (an array). An empty array is a normal, successful answer and is charged like any other; a source that reports "nothing found" as an error returns a free 404 not_found instead.

Also known as: /youtube/videos/trending on APIs that nest their paths. See Alternatives and equivalents.

What it costs#

2 credits for a fresh fetch, charged only when it succeeds.
Free when served from cache (0.2 credit for a cached response over 100 KB).
Free if the request is invalid (never charged) or the source fails or reports not found (refunded).

Parameters#

Name	Type	Required	Default	What it is	Constraints
`region`	string	no	`US`	2-letter region code	max 2 chars; must match `[A-Z]{2}`; trimmed

Request#

curl "https://api.onekey.dev/v1/youtube/trending?region=US" \

Field mapping#

How this endpoint's source fields become Onekey's unified schema. Fields the source lacks come back as null.

Source path	Onekey field	Transform
`id`	`content.id`	-
`snippet.title`	`content.title`	-
`snippet.description`	`content.text`	-
`snippet.publishedAt`	`content.createdAt`	`toIsoDate`
`snippet.channelId`	`author.id`	-
`snippet.channelTitle`	`author.displayName`	-
`snippet.thumbnails.high.url`	`media.thumbnailUrl`	`safeUrl`
`contentDetails.duration`	`ext.duration`	-
`statistics.viewCount`	`engagement.views`	`toNumber`
`statistics.likeCount`	`engagement.likes`	`toNumber`
`statistics.commentCount`	`engagement.comments`	`toNumber`

Caching and freshness#

Fresh for about 30 seconds. Repeat calls in that window are served from cache and are free.
Between 30 seconds and 5 minutes the cached copy is still served instantly and marked stale: true while Onekey refreshes it in the background.
If the source is down when a refresh is needed, the last copy can be served for up to 10 minutes more (marked stale).
A "not found" is remembered for 1 minute and is free.
The cache is shared across all customers, which is what keeps repeat calls cheap.

What can go wrong#

Status	Code	What to do
401	`unauthorized`	Check the `x-api-key` header.
402	`insufficient_credits`	Add credits; your balance must cover the price.
404	`not_found`	Unknown endpoint path.
422	`invalid_params`	Fix the parameters using the table above. Free.
429	`rate_limited`	Wait `Retry-After` seconds, then retry.
502	`upstream_error`	The source failed. Refunded; retry with backoff.

See Errors for the full list and retry guidance.
