youtube.channels_batch

beta Standard

Details and statistics for up to 10 YouTube channels in one call.

GET /v1/youtube/channels_batch

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/channels on APIs that nest their paths. See Alternatives and equivalents.

What it costs#

Standard · 1 credit 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
`ids`	string	yes	(required)	Comma-separated YouTube channel ids (UC..., 1 to 10)	max 249 chars; must match `UC[A-Za-z0-9_-]{22}(?:,UC[A-Za-z0-9_-]{22}){0,9}`; trimmed

Request#

curl "https://api.onekey.dev/v1/youtube/channels_batch?ids=UCuAXFkgsw1L7xaCfnd5JJOw" \

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`	`author.id`	-
`snippet.title`	`author.displayName`	-
`snippet.description`	`author.bio`	-
`snippet.customUrl`	`author.username`	-
`snippet.publishedAt`	`author.createdAt`	`toIsoDate`
`snippet.thumbnails.high.url`	`author.avatarUrl`	`safeUrl`
`statistics.subscriberCount`	`author.followers`	`toNumber`
`statistics.videoCount`	`author.contentCount`	`toNumber`
`statistics.viewCount`	`engagement.views`	`toNumber`

Caching and freshness#

Fresh for about 2 minutes. Repeat calls in that window are served from cache and are free.
Between 2 minutes and 15 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 1 hour 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.
