# Endpoints
|
||
|
||
Set these for the examples below:
|
||
|
||
```bash
|
||
export BASE_URL="http://localhost:3000" # local / self-hosted app
|
||
export API_KEY="s2yt_live_your_key_here"
|
||
```
|
||
|
||
Live HTML docs: [docs.songs2vid.com/docs/api/endpoints](https://docs.songs2vid.com/docs/api/endpoints).
|
||
|
||
## Discovery
|
||
|
||
```bash
|
||
curl "$BASE_URL/api/v1"
|
||
```
|
||
|
||
Returns the endpoint list and requirements (**no auth**). No billing routes are listed or implemented.
|
||
|
||
## Upload a file (two-step)
|
||
|
||
```bash
|
||
curl -X POST "$BASE_URL/api/v1/upload" \
|
||
-H "Authorization: Bearer $API_KEY" \
|
||
-F "file=@cover.jpg" \
|
||
-F "type=image"
|
||
```
|
||
|
||
```bash
|
||
curl -X POST "$BASE_URL/api/v1/upload" \
|
||
-H "Authorization: Bearer $API_KEY" \
|
||
-F "file=@track1.mp3" \
|
||
-F "type=audio"
|
||
```
|
||
|
||
```bash
|
||
# Optional: PNG watermark logo
|
||
curl -X POST "$BASE_URL/api/v1/upload" \
|
||
-H "Authorization: Bearer $API_KEY" \
|
||
-F "file=@logo.png" \

# Optional: custom font (.ttf / .otf, max 10 MB)
|
||
curl -X POST "$BASE_URL/api/v1/upload" \
|
||
-H "Authorization: Bearer $API_KEY" \
|
||
-F "file=@Brand.ttf" \
|

-F "type=font"
|
||
```
|
||
|
||
### Request fields
|
||
|
||
| Field | Required | Notes |
|
||
|-------|----------|--------|
|
||
| `file` | Yes | Multipart file |
|
||
| `type` | Yes | `image` \| `audio` \| `logo` \| `font` |
|
||
|
||
### Allowed files
|
||
|
||
| `type` | Formats | Max size |
|
||
|--------|---------|----------|
|
||
| `image` | JPEG, PNG, WebP, GIF | 500 MB |
|
||
| `audio` | MP3, WAV, FLAC | 500 MB |
|
||
| `logo` | PNG only | 500 MB |
|
||
| `font` | `.ttf` / `.otf` | **10 MB** |
|
||
|
||
### Response
|
||
|
||
```json
|
||
{
|
||
"path": "/uploads/.../track.mp3",
|
||
"filename": "track.mp3",
|
||
"size": 4123456,
|
||
"audioTags": {
|
||
"title": "Song Title",
|
||
"artist": "Artist Name",
|
||
"album": "Album",
|
||
"genre": "Electronic",
|
||
"year": "2024"
|
||
}
|
||
}
|
||
```
|
||
|
||
`audioTags` is present for MP3 when tags are readable; otherwise `null`.
|
||
|
||
## Create job / render from paths (recommended)
|
||
|
||
Self-hosted unlocks per-track covers, custom watermarks/fonts, and art-track layouts. Max batch size: **100**. Watermarks are optional — nothing forces the default Songs2VID badge.
|
||
|
||
`POST /api/v1/render` is an **n8n-friendly alias** of `POST /api/v1/jobs` (identical body and response). `GET /api/v1/render` lists jobs like `GET /api/v1/jobs`.
|
||
|
||
Optional `webhookUrl` (absolute `http(s)` URL) makes Songs2VID POST JSON when items/jobs finish — preferred for n8n.
|
||
|
||
```bash
|
||
curl -X POST "$BASE_URL/api/v1/render" \
|
||
-H "Authorization: Bearer $API_KEY" \
|
||
-H "Content-Type: application/json" \
|
||

|

|

"watermark": {

"fontKey": "montserrat",
|

|

|
||
},
|
||
"playlistId": null
|
||
}
|
||
}]
|
||
}'
|
||
```
|
||
|
||
Equivalent path: `POST $BASE_URL/api/v1/jobs` with the same JSON.
|
||
|
||
### Success response
|
||
|
||
```json
|
||
{
|
||
"jobId": "clxxxxxxxx",
|
||
"itemCount": 1,
|
||
"status": "PENDING",
|
||
"statusUrl": "/api/v1/jobs/clxxxxxxxx",
|
||
"webhookUrl": "https://your-n8n.example/webhook/songs2vid-complete",
|
||
"playlist": null
|
||
}
|
||
```
|
||
|
||

|
||
### Watermark fields
|
||
|
||
`watermark.mode`: `none` | `default` | `text` | `logo`
|
||
|
||
- `none` — no overlay
|
||
- `default` — built-in Songs2VID badge PNG (`assets/watermark.png`)
|
||
- `logo` — requires prior `type=logo` upload; set `logoPath`
|
||
- `text` — custom string (max **80**); set `text`
|
||
|
||
`watermark.position`: `top-left` | `top-right` | `bottom-left` | `bottom-right` | `center`
|
||
|
||
`watermark.offsetX` / `offsetY`: `0`–`200` (default `20`)
|
||
|
||
`watermark.fontKey`: `system` | `inter` | `montserrat` | `roboto` | `oswald` | `playfair` | `custom` (styles art-track text and text watermarks)
|
||
|
||
### Art-track layouts
|
||
|
||
`metadata.layout.template` (or flat `layout_template` / `layoutTemplate`). Valid enums are also listed on `GET /api/v1` as `layoutTemplates`. Mirrored pairs used by the Layout Studio composition grid are listed under `compositionFamilies` (`side`: cover beside text; `lower`: lower corner).
|
||
|
||
| Enum | Description |
|
||
|------|-------------|
|
||
| `COVER_LEFT_TEXT_RIGHT` | Cover left, title & artist right |
|
||
| `COVER_TOP_TEXT_BOTTOM` | Cover top, title & artist below |
|
||
| `COVER_RIGHT_TEXT_LEFT` | Cover right, title & artist left |
|
||
| `CENTERED_COMPACT` | Centered cover + text stack |
|
||
| `LOWER_LEFT_COVER_TEXT` | Lower-left cover; `textPadding` is equal left + bottom inset (diagonal from frame corner) with title/artist to the right |
|
||
| `LOWER_RIGHT_COVER_TEXT` | Lower-right cover; `textPadding` is equal right + bottom inset (diagonal from frame corner) with title/artist to the left |
|
||
|
||
For lower-corner templates only, optional `metadata.backgroundImagePath` (or `background_image_path`) sets a separate full-frame blur fill. Upload with `type=image` first, then pass the returned path. The cover (`imagePath` / per-item `metadata.imagePath`) stays the sharp corner square. Omit the field to blur the cover itself (default). `blurAmount` / `blurOpacity` still apply to whichever image is used as the fill.
|
||
|
||
Optional fine-tuning (clamped; camelCase or snake_case):
|
||
|
||
| Field | Range | Default | Purpose |
|
||
|-------|-------|---------|---------|
|
||
| `blurAmount` / `blur_amount` | 0–100 | 55 | Background `boxblur` intensity |
|
||
| `blurOpacity` / `blur_opacity` | 0–100 | 100 | Blurred fill vs black |
|
||
| `blurFill` / `blur_fill` | boolean | `false` | Classic letterbox only: fill bars with blurred cover (ignored for art-track templates) |
|
||
| `textPadding` / `text_padding` | 16–120 | 48 | Edge inset for cover/text. On lower-corner templates this value is applied equally on both axes (left=bottom or right=bottom) so the cover corner sits on a true diagonal from the frame corner |
|
||
| `titleArtistGap` / `title_artist_gap` | 0–64 | 10 | Space between title and artist |
|
||
| `titleBold` / `title_bold` | boolean | `true` | Bold song title (preview + FFmpeg) |
|
||
| `textOffsetX` / `text_offset_x` | −120–120 | 0 | Shift text block horizontally |
|
||
| `textOffsetY` / `text_offset_y` | −120–120 | 0 | Shift text block vertically |
|
||
|
||
Also set `metadata.songTitle` (max 120) and `metadata.artist` (max 80) for the on-video text lines. `metadata.title` remains the YouTube title.
|
||
|
||
Omit `layout.template` for classic letterbox (black-padded cover by default). Set `layout.blurFill` / `blur_fill` to `true` to fill letterbox bars with a blurred cover; then `blurAmount` / `blurOpacity` apply. Free-form cover coordinates (`x`, `y`, `coverX`, …) and layout-level `offsetX`/`offsetY` are **rejected**.
|
||
|
||
Invalid template strings return **400**:
|
||
|
||
```json
|
||
{ "error": "Invalid layout template. Refer to API documentation for valid enum values." }
|
||
```
|
||
|
||
## YouTube playlists
|
||
|
||
```bash
|
||
curl "$BASE_URL/api/v1/playlists" \
|
||
-H "Authorization: Bearer $API_KEY"
|
||
```
|
||
|
||
```bash
|
||
curl -X POST "$BASE_URL/api/v1/playlists" \
|
||
-H "Authorization: Bearer $API_KEY" \
|
||
-H "Content-Type: application/json" \
|
||
-d '{"title":"My Album","description":"From Songs2VID","privacy":"unlisted"}'
|
||
```
|
||
|
||
Or pass `createPlaylist` on a job / batch body to create a playlist and attach all videos.
|
||
|
||
## One-shot batch (small packs only)
|
||
|
||
```bash
|
||
curl -X POST "$BASE_URL/api/v1/jobs/batch" \
|
||
-H "Authorization: Bearer $API_KEY" \
|
||
-F "image=@cover.jpg" \
|
||
-F "audio=@track1.mp3" \
|
||
-F "audio=@track2.mp3" \
|
||
-F 'metadata={"defaults":{"privacy":"PUBLIC"},"items":[{"title":"Track One"},{"title":"Track Two"}]}'
|
||
```
|
||
|
||
Prefer two-step upload + jobs for larger packs.
|
||
|
||
## Poll job status
|
||
|
||
```bash
|
||
curl "$BASE_URL/api/v1/jobs/JOB_ID" \
|
||
-H "Authorization: Bearer $API_KEY"
|
||
```
|
||
|
||
```bash
|
||
curl "$BASE_URL/api/v1/jobs?limit=10" \
|
||
-H "Authorization: Bearer $API_KEY"
|
||
```
|
||
|
||
`GET /api/v1/jobs` accepts `limit` (default **20**, max **100**).
|
||
|
||
