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
`transcript`	`content.text`	-
`language`	`content.language`	-
`duration`	`media.durationSeconds`	`toNumber`

Caching and freshness#

Fresh for about 5 minutes. Repeat calls in that window are served from cache and are free.
Between 5 minutes and 1 hour 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 1 minute and is free.
The cache is shared across all customers, which is what keeps repeat calls cheap.

What can go wrong#
