## Penggunaan API

MuApi menggunakan pola **kirim-lalu-jajak pendapat**: kirimkan pekerjaan, dapatkan `request_id`, lalu lakukan polling titik akhir prediksi hingga `status` menjadi `selesai`. Secara opsional, teruskan `?webhook=YOUR_URL` pada panggilan kirim untuk menerima panggilan balik POST ketika pekerjaan selesai (lewati polling).

**Otentikasi**: kirim kunci MuApi Anda di header `x-api-key`. Dapatkan satu di https://muapi.ai/access-keys.

**Tanggapan:**

```

### 2. Polling hasil

```http
GET https://api.muapi.ai/api/v1/predictions/{request_id}/result
x-api-key: YOUR_API_KEY
```

Nilai `status` yang mungkin: `antrian`, `tertunda`, `sedang diproses`, `selesai`, `gagal`, `dibatalkan`. Jajak pendapat setiap 2-5 detik hingga terminal. Saat `selesai`, URL hasil berada dalam larik `outputs`.

**Contoh respon ketika `selesai`:**

```json
{
  "id": "abc123",
  "status": "completed",
  "outputs": [
    "https://cdn.muapi.ai/.../output.png"
  ],
  "urls": {
    "get": "https://api.muapi.ai/api/v1/predictions/abc123/result"
  },
  "created_at": "2026-05-08T12:34:56Z",
  "has_nsfw_contents": []
}
```

## Webhook (opsional)

Tambahkan `?webhook=https://server-Anda/path` ke URL pengiriman. Saat tugas mencapai status terminal, MuApi akan POST dalam bentuk yang sama dengan respons polling ke URL Anda — tidak perlu polling.

## Integrasi Agen

MuApi mengirimkan server MCP dan CLI sehingga agen (Claude Code, Cursor, custom) dapat memanggil endpoint ini tanpa menulis kode HTTP:

```bash
# Instal CLI
npm install -g muapi-cli

# Autentikasi sekali
muapi auth login

# Paparkan semua model MuApi sebagai alat MCP kepada agen Anda
muapi mcp serve
```

Server MCP menampilkan alat yang menggabungkan pengiriman + jajak pendapat untuk setiap model, termasuk `gemini-3-8-flash-tts`. Lihat `muapi --help` untuk pintasan khusus kategori (`muapi image generate`, `muapi video from-image`, dll.).
