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`	`entity.id`	-
`attributes.canonicalTitle`	`entity.name`	-
`attributes.synopsis`	`entity.description`	-
`attributes.status`	`entity.status`	-
`attributes.subtype`	`entity.type`	-
`attributes.startDate`	`event.startDate`	-
`attributes.averageRating`	`entity.stats.score`	`toNumber`
`attributes.popularityRank`	`ext.popularityRank`	`toNumber`
`attributes.posterImage.small`	`media.thumbnailUrl`	`safeUrl`
`attributes.chapterCount`	`ext.chapters`	`toNumber`

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.
