# Endpoints

Set these for the examples below:

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" \
  -F "type=logo"
```

```bash
# 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 |

### 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 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.

```bash
curl -X POST "$BASE_URL/api/v1/jobs" \

### Watermark fields

- `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)

Fine-tuning (defaults in parentheses): `blurAmount` (55), `blurOpacity` (100), `textPadding` (48), `titleArtistGap` (10), `textOffsetX` (0), `textOffsetY` (0).

## 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**).
