## Autentikasi

**Authorization** `string` *required*

Semua endpoint memerlukan autentikasi Bearer Token

Dapatkan API Key:

Kunjungi [Halaman Manajemen API Key](https://gccai.heqingsong.uk/keys) untuk mendapatkan API Key Anda

Tambahkan ke header permintaan:

```
Authorization: Bearer YOUR_API_KEY
```

## Parameter Permintaan

**model** `string` *required*

Nama model pembuatan video, tetap sebagai `wan2.6-i2v-flash`

**nsfw\_check** `boolean` (default: false)

Menentukan apakah moderasi konten dijalankan sebelum tugas video dikirim.

* `true`: periksa prompt dan gambar input dengan `omni-moderation-latest`
* `false` atau dihilangkan: tidak mengirim permintaan moderasi, tanpa biaya atau latensi moderasi tambahan (default)

**image\_urls** `array\<string\>` *required*

Array URL gambar referensi (hanya 1 gambar frame pertama didukung)

Mendukung URL gambar yang dapat diakses publik atau encoding Base64 (`data:image/png;base64,...`)

Contoh: `["https://example.com/image.jpg"]`

> [!NOTE]
>
> Persyaratan gambar:
>
> * Format: JPEG, JPG, PNG (tanpa transparansi), BMP, WEBP
> * Resolusi: rentang lebar/tinggi 240-8000 piksel
> * Ukuran: ≤ 10MB

**prompt** `string`

Deskripsi konten video

Opsional tetapi direkomendasikan untuk gambar-ke-video, menjelaskan aksi dan efek yang diharapkan

Tentukan subjek, aksi, kamera, dan gaya dengan jelas untuk hasil yang lebih baik

Contoh: `"The person in the image smiles and waves, camera slowly zooms in"`

**negative\_prompt** `string`

Prompt negatif, menjelaskan konten yang tidak diinginkan

Maksimum 500 karakter

Contoh: `"blurry, low quality, distorted"`

**resolution** `string` (default: 1080p)

Resolusi video

Opsi:

* `720p` - HD
* `1080p` - FHD (default)

Default: `1080p`

> [!NOTE]
>
> Resolusi secara langsung memengaruhi harga, 1080p lebih mahal daripada 720p. Rasio aspek ditentukan oleh gambar input.

**duration** `integer` (default: 5)

Durasi video (detik)

Rentang yang didukung: `2` hingga `15` detik (integer)

Default: `5`

**audio** `boolean` (default: true)

Apakah membuat audio

Atur ke `true`: otomatis membuat musik latar/efek suara yang sesuai (default)

Atur ke `false`: menghasilkan video tanpa suara

Default: `true`

> [!NOTE]
>
> Tidak didukung saat model adalah `wan2.6-i2v`.

**audio\_url** `string`

URL audio kustom (wav/mp3, 3-30 detik, ≤ 15MB)

Prioritas lebih rendah daripada `audio`: diabaikan saat `audio=false`

Jika audio lebih panjang dari durasi video, audio akan dipotong; jika lebih pendek, bagian sisanya tanpa suara

> [!WARNING]
>
> Persyaratan file audio:
>
> * Format: wav, mp3
> * Durasi: 3-30 detik
> * Ukuran: ≤ 15MB

**prompt\_extend** `boolean` (default: true)

Apakah mengaktifkan penulisan ulang prompt cerdas

Secara signifikan meningkatkan hasil untuk prompt yang lebih pendek, tetapi menambah waktu pemrosesan

Default: `true`

**shot\_type** `string`

Tipe shot, memerlukan `prompt_extend=true`

Opsi:

* `single` - Shot tunggal (default), menghasilkan video shot tunggal berkesinambungan
* `multi` - Multi-shot, menghasilkan video naratif dengan beberapa transisi shot

> [!NOTE]
>
> `shot_type` berprioritas lebih tinggi daripada `prompt`. Bahkan jika prompt menyebutkan "multi-shot", mengatur `single` akan tetap menghasilkan shot tunggal.

**seed** `integer`

Random seed (≥0), menetapkan seed yang sama dapat mereproduksi hasil serupa

Contoh: `12345`

**watermark** `boolean` (default: false)

Apakah menambahkan watermark "AI Dihasilkan" (kanan bawah)

Default: `false`

## Kontrol Audio

| Kombinasi Parameter | Hasil |
| - | - |
| Tanpa `audio` atau `audio_url` | Audio dibuat otomatis (default) |
| `audio_url: "https://..."` | Gunakan audio yang ditentukan |
| `audio: false` | Video tanpa suara |
| `audio: false` + `audio_url: "..."` | Video tanpa suara (`audio` berprioritas lebih tinggi) |

## Respons

**code** `integer`

Kode status respons, 200 jika berhasil

**data** `array`

Array data respons

**Elemen array**

**status** `string`

Status tugas, `submitted` saat pengiriman awal

**task\_id** `string`

Pengidentifikasi tugas unik untuk mengueri status dan hasil tugas

## Kasus Penggunaan

### Kasus 1: Permintaan Minimal

```json theme={null}
{
  "model": "wan2.6-i2v-flash",
  "image_urls": ["https://example.com/image.jpg"]
}
```

### Kasus 2: Parameter Lengkap

```json theme={null}
{
  "model": "wan2.6-i2v-flash",

  "image_urls": ["https://example.com/image.jpg"],
  "negative_prompt": "blurry, low quality, distorted",
  "resolution": "1080p",
  "duration": 10,
  "seed": 12345,
  "prompt_extend": true,
  "shot_type": "multi",
  "audio": true,
  "watermark": false
}
```

### Kasus 3: Audio Kustom

```json theme={null}
{
  "model": "wan2.6-i2v-flash",
  "prompt": "Person dancing to the music",
  "image_urls": ["https://example.com/dancer.jpg"],
  "audio_url": "https://example.com/music.mp3",
  "resolution": "1080p",
  "duration": 10
}
```

### Kasus 4: Video Tanpa Suara

```json theme={null}
{
  "model": "wan2.6-i2v-flash",
  "prompt": "Flower slowly blooming",
  "image_urls": ["https://example.com/flower.jpg"],
  "audio": false,
  "resolution": "720p",
  "duration": 5

  "duration": 5
}
```

> [!NOTE]
>
> **Kueri Hasil Tugas**
>
> Pembuatan video adalah tugas asinkron yang mengembalikan `task_id` saat dikirim. Gunakan endpoint [Dapatkan Status Tugas](https://gccai.heqingsong.uk/id/api-reference/tasks/status.md) untuk mengueri progres dan hasil pembuatan.
