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
`tradeCount`	`ext.tradeCount`	`toNumber`
`memberCount`	`ext.memberCount`	`toNumber`
`tickerCount`	`ext.tickerCount`	`toNumber`
`filingCount`	`ext.filingCount`	`toNumber`
`ptrFilingsIndexed`	`ext.filingsIndexed`	`toNumber`
`ptrFilingsParsed`	`ext.filingsParsed`	`toNumber`
`firstTradeDate`	`ext.firstTradeDate`	`toIsoDate`
`latestTradeDate`	`ext.latestTradeDate`	`toIsoDate`
`chambers`	`ext.chambers`	-
`lastIngestAt`	`ext.lastIngestAt`	`toIsoDate`
`source`	`ext.source`	-

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 2 minutes and is free.
The cache is shared across all customers, which is what keeps repeat calls cheap.

What can go wrong#
