What you get#
Onekey exposes Docker Hub as 6 endpoints behind one API key: 3 endpoints return one record (data is an object) and 3 endpoints return a list (data is an array). Every answer uses the same envelope (success, data, metadata, error), the cost is reported in metadata.credits_charged, and fields are mapped onto the unified schema so the code you write for Docker Hub also works for the rest of the developer platforms category.
Endpoints#
| Endpoint | What it does | Parameters | Credits | Status |
|---|---|---|---|---|
namespace_repos | Public repositories of a Docker Hub user or organisation. | namespace* | 5 | stable |
repo | Docker Hub repository metadata (stars, pulls). | namespace*, repo* | 1 | stable |
search | Search Docker Hub repositories. | q* | 5 | stable |
tag | Details of one Docker Hub image tag. | namespace*, repo*, tag* | 1 | stable |
tags | Most recently pushed tags of a Docker Hub repository. | namespace*, repo* | 5 | stable |
user | Docker Hub user or organisation profile. | name* | 1 | stable |
A * marks a required parameter. Each endpoint name links to its reference page with the full parameter table, caching window and a recorded response.
Make a request#
This calls dockerhub.repo (1 credit, stable). Replace YOUR_API_KEY with your key; sign up, no card. 1,000 free credits cover the open-platform endpoints. Hard-to-reach platforms (X, TikTok, Instagram, Reddit, and others marked on their page) need a verified email and a purchased pack.
curl "https://api.onekey.dev/v1/dockerhub/repo?namespace=library&repo=nginx" \
-H "x-api-key: YOUR_API_KEY"Fields you get back#
These unified fields come back from Docker Hub, with the same names as on every other platform. The count is how many of its 6 mapped endpoints return the field; a field the source lacks is null, never missing. 7 platform-specific fields (ext.<name>) come on top, documented on each endpoint page.
| Field | Type | Endpoints |
|---|---|---|
entity.name | string | 5 |
entity.updatedAt | ISO 8601 date | 4 |
entity.description | string | 3 |
entity.stats.stars | integer | 3 |
author.username | string | 2 |
entity.createdAt | ISO 8601 date | 2 |
entity.status | string | 2 |
package.namespace | string | 2 |
author.createdAt | ISO 8601 date | 1 |
author.displayName | string | 1 |
author.id | string | 1 |
author.location | string | 1 |
author.type | string | 1 |
author.url | URL | 1 |
The full schema is in Unified schema.
