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
`ticker`	`market.symbol`	-
`name`	`entity.name`	-
`finnhubIndustry`	`entity.category`	-
`exchange`	`market.exchange`	-
`country`	`ext.country`	-
`currency`	`market.currency`	-
`marketCapitalization`	`market.marketCap`	`toNumber`
`shareOutstanding`	`ext.sharesOutstanding`	`toNumber`
`weburl`	`entity.url`	`safeUrl`
`logo`	`media.thumbnailUrl`	`safeUrl`
`ipo`	`entity.createdAt`	`toIsoDate`

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.

What can go wrong#
