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
`data.children.0.data.id`	`content.id`	-
`data.children.0.data.title`	`content.title`	-
`data.children.0.data.selftext`	`content.text`	-
`data.children.0.data.url`	`content.url`	`safeUrl`
`data.children.0.data.created_utc`	`content.createdAt`	`toIsoDate`
`data.children.0.data.author`	`author.username`	-
`data.children.0.data.subreddit`	`entity.name`	-
`data.children.0.data.score`	`engagement.likes`	`toNumber`
`data.children.0.data.num_comments`	`engagement.comments`	`toNumber`
`data.children.0.data.upvote_ratio`	`engagement.upvoteRatio`	`toNumber`
`data.children.0.data.thumbnail`	`media.thumbnailUrl`	`safeUrl`

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.
