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`	-
`version`	`package.version`	-
`app_version`	`ext.appVersion`	-
`description`	`entity.description`	-
`stars`	`entity.stats.stars`	`toNumber`
`repository.name`	`ext.repository`	-
`repository.organization_name`	`author.username`	-
`repository.verified_publisher`	`ext.verifiedPublisher`	`toBoolean`
`ts`	`entity.updatedAt`	`toIsoDate`
`deprecated`	`package.deprecated`	`toBoolean`

`keywords`	`entity.tags`	-

Caching and freshness#

Fresh for about 1 hour. Repeat calls in that window are served from cache and are free.
Between 1 hour and 1 day 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 3 days 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#

Status	Code	What to do
401	`unauthorized`	Check the `x-api-key` header.
402	`insufficient_credits`	Add credits; your balance must cover the price.
404	`not_found`	That record does not exist. Free; do not retry.
422	`invalid_params`	Fix the parameters using the table above. Free.
429	`rate_limited`	Wait `Retry-After` seconds, then retry.
502	`upstream_error`	The source failed. Refunded; retry with backoff.
