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
`metadata.channelMetadataRenderer.externalId`	`author.id`	-
`metadata.channelMetadataRenderer.title`	`author.displayName`	-
`header.pageHeaderRenderer.content.pageHeaderViewModel.metadata.contentMetadataViewModel.metadataRows.0.metadataParts.0.text.content`	`author.username`	-
`metadata.channelMetadataRenderer.vanityChannelUrl`	`author.url`	`safeUrl`
`header.pageHeaderRenderer.content.pageHeaderViewModel.metadata.contentMetadataViewModel.metadataRows.1.metadataParts.0.text.content`	`ext.followersText`	-
`header.pageHeaderRenderer.content.pageHeaderViewModel.metadata.contentMetadataViewModel.metadataRows.1.metadataParts.1.text.content`	`ext.videosText`	-
`metadata.channelMetadataRenderer.description`	`content.text`	-
`metadata.channelMetadataRenderer.avatar.thumbnails.0.url`	`author.avatarUrl`	`safeUrl`
`metadata.channelMetadataRenderer.isFamilySafe`	`ext.familySafe`	`toBoolean`

Caching and freshness#

Fresh for about 30 minutes. Repeat calls in that window are served from cache and are free.
Between 30 minutes and 6 hours 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 day more (marked stale).
A "not found" is remembered for 5 minutes and is free.
The cache is shared across all customers, which is what keeps repeat calls cheap.
