Media library

Media library endpoints of the Zanfia Workspace API, with schemas and code samples.

10 min readLast updated Oct 8, 2026

Upload files and videos for use in lessons and pages. Videos transcode after upload — poll the media item until uploadStatus is ready. You can also generate images with AI (synchronous; spends the workspace's AI credits) and start video transcription (spends transcription minutes; returns 202 — poll GET /media/{mediaId}/transcript for the result). All routes require a Authorization: Bearer header — see Authentication.

List media

GET/media

Authorization

bearerAuth

AuthorizationBearer <token>

API key from Dashboard → Integrations → API, MCP and CLI.

In: header

Query Parameters

folder?string

Response Body

`application/json`

curl -X GET "https://example.com/media"

{  "count": 0,  "media": [    {      "id": "string",      "name": "string",      "type": "string",      "mimeType": "string",      "size": 0,      "url": "string",      "thumbnailUrl": "string",      "video": {        "bunnyLibraryId": "string",        "bunnyVideoId": "string"      },      "folder": "string",      "uploadStatus": "string",      "createdAt": "string"    }  ]}

{  "error": "string",  "message": "string"}

Upload a file

POST/media

Authorization

bearerAuth

AuthorizationBearer <token>

API key from Dashboard → Integrations → API, MCP and CLI.

In: header

Request Body

application/json

TypeScript Definitions

Use the request body type in TypeScript.

name*string

Original file name — sanitized for the stored object + Media Library label.

mimeType*string

MIME type, e.g. image/png.

data*string

Base64-encoded file bytes (no data: prefix).

folder?string

Optional Media Library folder name.

description?string

Optional human description stored on the media doc.

Response Body

`application/json`

curl -X POST "https://example.com/media" \  -H "Content-Type: application/json" \  -d '{    "name": "string",    "mimeType": "string",    "data": "string"  }'

{  "mediaId": "string",  "url": "string",  "storagePath": "string"}

{  "error": "string",  "message": "string"}

Start a video upload

POST/media/videos/initiate-upload

Authorization

bearerAuth

AuthorizationBearer <token>

API key from Dashboard → Integrations → API, MCP and CLI.

In: header

Request Body

application/json

TypeScript Definitions

Use the request body type in TypeScript.

Begin a Bunny video upload: provisions a Bunny video object + a Pending MediaDocument, and returns a signed TUS credential. The caller then uploads the bytes DIRECTLY to Bunny (the file never passes through the API), and polls GET /media/:mediaId until uploadStatus is ready (Bunny finalizes via webhook).

title*string

sourceSizeBytes*number

Source-file byte count — persisted as MediaDocument.size and used for the quota pre-check.

Response Body

`application/json`

curl -X POST "https://example.com/media/videos/initiate-upload" \  -H "Content-Type: application/json" \  -d '{    "title": "string",    "sourceSizeBytes": 0  }'

{  "mediaId": "string",  "bunnyVideoId": "string",  "bunnyLibraryId": "string",  "signature": "string",  "expire": 0}

{  "error": "string",  "message": "string"}

Generate an AI image

POST/media/ai-images

Authorization

bearerAuth

AuthorizationBearer <token>

API key from Dashboard → Integrations → API, MCP and CLI.

In: header

Request Body

application/json

TypeScript Definitions

Use the request body type in TypeScript.

Generate ONE AI image into the Media Library. Synchronous (up to ~1 min); spends the workspace's AI credits. 402 no-credits, 413 storage-quota-exceeded, 502 image-generation-failed.

prompt*string

The creator's prompt (platform single-graphic guards are appended server-side).

aspectRatio*AIImageAspectRatio

Aspect ratio = the SHAPE of the generated image, independent of resolution. The value is the literal string the provider expects (Gemini's image_config.aspect_ratio), so the UI control is the single source of truth and no pixel mapping is needed.

Curated to the formats a non-technical creator actually publishes — labelled by use-case in the UI (Square / Portrait / Story / Widescreen), not pixels.

Value in

"1:1"
"4:5"
"9:16"
"16:9"

quality*AIImageQuality

Clamped to what the configured model supports.

Value in

"1K"
"2K"
"4K"

folder?string

Media Library folder NAME to file the image under.

textLanguage?string

Language code any text rendered inside the image must use (e.g. pl).

Response Body

`application/json`

curl -X POST "https://example.com/media/ai-images" \  -H "Content-Type: application/json" \  -d '{    "prompt": "string",    "aspectRatio": "1:1",    "quality": "1K"  }'
