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
`name`	`entity.name`	-
`symbol`	`market.symbol`	-
`url`	`entity.url`	`safeUrl`
`category`	`entity.category`	-
`total24h`	`ext.fees24h`	`toNumber`
`total7d`	`ext.fees7d`	`toNumber`
`total30d`	`ext.fees30d`	`toNumber`
`totalAllTime`	`ext.feesAllTime`	`toNumber`

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#

401	`unauthorized`	Check the `x-api-key` header.
402	`insufficient_credits`	Add credits; your balance must cover the price.
