What you get#
Onekey exposes Flathub as 5 endpoints behind one API key: 2 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 Flathub also works for the rest of the developer platforms category.
Endpoints#
| Endpoint | What it does | Parameters | Credits | Status |
|---|---|---|---|---|
app | Flathub app details by application id. | app_id* | 1 | stable |
popular | Popular Flathub apps. | - | 5 | stable |
recently_added | Recently added Flathub applications. | - | 5 | stable |
search | Search Flathub applications. | q* | 5 | stable |
summary | Flathub install size and architectures of an application. | app_id* | 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 flathub.app (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.

-H "x-api-key: YOUR_API_KEY"Fields you get back#
These unified fields come back from Flathub, with the same names as on every other platform. The count is how many of its 5 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.id | string | 5 |
entity.description | string | 4 |
entity.name | string | 4 |
package.license | string | 3 |
author.displayName | string | 2 |
media.thumbnailUrl | URL | 2 |
entity.tags | list of strings | 1 |
entity.updatedAt | ISO 8601 date | 1 |
entity.url | URL | 1 |
package.version | string | 1 |
The full schema is in Unified schema.
