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
`trackId`	`entity.id`	`toNumber`
`trackName`	`entity.name`	-
`trackViewUrl`	`entity.url`	`safeUrl`
`artistName`	`author.displayName`	-
`collectionName`	`ext.album`	-
`artworkUrl100`	`media.thumbnailUrl`	`safeUrl`
`previewUrl`	`media.audioUrl`	`safeUrl`
`trackTimeMillis`	`ext.durationMs`	`toNumber`
`releaseDate`	`entity.releaseDate`	`toIsoDate`
`primaryGenreName`	`entity.category`	-

Caching and freshness#

Fresh for about 1 hour. Repeat calls in that window are served from cache and are free.
Between 1 hour and 1 day 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 3 days 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.

What can go wrong#

401	`unauthorized`	Check the `x-api-key` header.

422	`invalid_params`	Fix the parameters using the table above. Free.
