stable Advanced

Public GitLab.com projects by topic (most starred first).

GET /v1/gitlab/topic_projects

What you get#

A list of GitLab results in Onekey's unified shape, in data (an array). An empty array is a normal, successful answer and is charged like any other; a source that reports "nothing found" as an error returns a free 404 not_found instead.

What it costs#

Advanced · 5 credits for a fresh fetch, charged only when it succeeds.
Free when served from cache (0.2 credit for a cached response over 100 KB).
Free if the request is invalid (never charged) or the source fails or reports not found (refunded).

Parameters#

Name	Type	Required	Default	What it is	Constraints
`topic`	string	yes	(required)	Topic	max 50 chars; must match `[a-z0-9][a-z0-9._-]{0,49}`; trimmed, lowercased

Request#

curl "https://api.onekey.dev/v1/gitlab/topic_projects?topic=cli" \
  -H "x-api-key: YOUR_API_KEY"

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
`id`	`entity.id`	`toString`
`path_with_namespace`	`entity.name`	-
`description`	`entity.description`	-
`web_url`	`entity.url`	`safeUrl`
`star_count`	`entity.stats.stars`	`toNumber`
`forks_count`	`entity.stats.forks`	`toNumber`
`open_issues_count`	`entity.stats.openIssues`	`toNumber`
`created_at`	`entity.createdAt`	`toIsoDate`
`last_activity_at`	`entity.updatedAt`	`toIsoDate`
`default_branch`	`package.defaultBranch`	-
`namespace.path`	`author.username`	-
`namespace.web_url`	`author.url`	`safeUrl`
`topics`	`entity.tags`	-
`visibility`	`ext.visibility`	-

Caching and freshness#

Fresh for about 2 minutes. Repeat calls in that window are served from cache and are free.
Between 2 minutes and 15 minutes 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 hour more (marked stale).
A "not found" is remembered for 1 minute 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`	Unknown endpoint path.
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.

See Errors for the full list and retry guidance.

Status: stable (verified against the live source).
