What you get#
Onekey exposes Wikimedia Commons as 4 endpoints behind one API key: 1 endpoint 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 Wikimedia Commons also works for the rest of the entertainment, art & culture category.
Endpoints#
| Endpoint | What it does | Parameters | Credits | Status |
|---|---|---|---|---|
category_files | Files in a Wikimedia Commons category (first 50). | category* | 5 | stable |
file_info | Wikimedia Commons file: URL, size, license and description. | name* | 1 | stable |
random_files | Random Wikimedia Commons files. | - | 5 | stable |
search | Search Wikimedia Commons files. | q* | 5 | 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 commons.file_info (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/commons/file_info?name=Alan%20turing%20header.jpg" \
-H "x-api-key: YOUR_API_KEY"Fields you get back#
These unified fields come back from Wikimedia Commons, with the same names as on every other platform. The count is how many of its 4 mapped endpoints return the field; a field the source lacks is null, never missing.
| Field | Type | Endpoints |
|---|---|---|
content.id | string | 4 |
content.title | string | 4 |
content.text | string | 2 |
author.displayName | string | 1 |
content.updatedAt | ISO 8601 date | 1 |
media.height | integer | 1 |
media.mimeType | string | 1 |
media.sizeBytes | integer | 1 |
media.thumbnailUrl | URL | 1 |
media.url | URL | 1 |
media.width | integer | 1 |
package.license | string | 1 |
The full schema is in Unified schema.
