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
`company.company_number`	`entity.id`	-
`company.name`	`entity.name`	-
`company.jurisdiction_code`	`ext.jurisdiction`	-
`company.incorporation_date`	`content.createdAt`	`toIsoDate`
`company.current_status`	`entity.status`	-
`company.opencorporates_url`	`entity.url`	`safeUrl`
`company.registered_address_in_full`	`place.address`	-

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.

422	`invalid_params`	Fix the parameters using the table above. Free.
