## एपीआई उपयोग

MuApi **submit-then-poll** पैटर्न का उपयोग करता है: एक नौकरी सबमिट करें, एक `request_id` प्राप्त करें, फिर `status` `पूरा` होने तक पूर्वानुमान समापन बिंदु पर पोल करें। वैकल्पिक रूप से कार्य समाप्त होने पर POST कॉलबैक प्राप्त करने के लिए सबमिट कॉल पर `?webhook=YOUR_URL` पास करें (मतदान छोड़ें)।

**प्रमाणीकरण**: अपनी MuApi कुंजी को `x-api-key` हेडर में भेजें। https://muapi.ai/access-keys पर एक प्राप्त करें।

### 1. कार्य सबमिट करें

**प्रतिक्रिया:**

```json
{
  "request_id": "abc123",
  "status": "processing"
}
```

### 2. परिणाम पोल करें

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

संभावित `स्थिति` मान: `कतारबद्ध`, `लंबित`, `प्रसंस्करण`, `पूर्ण`, `विफल`, `रद्द`। टर्मिनल तक हर 2-5 सेकंड में मतदान करें। जब `पूर्ण` होता है, तो परिणाम यूआरएल `आउटपुट` सरणी में होते हैं।

**'पूरा' होने पर उदाहरण प्रतिक्रिया:**

```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": []
}
```

### cURL

```bash

## वेबहुक (वैकल्पिक)

सबमिट URL में `?webhook=https://your-server/path` जोड़ें। जब कार्य अंतिम स्थिति में पहुंच जाता है, तो MuApi आपके URL पर पोलिंग प्रतिक्रिया के समान आकार में पोस्ट करेगा - किसी पोलिंग की आवश्यकता नहीं है।

## एजेंट एकीकरण

MuApi एक MCP सर्वर और CLI शिप करता है ताकि एजेंट (क्लाउड कोड, कर्सर, कस्टम) HTTP कोड लिखे बिना इस एंडपॉइंट को कॉल कर सकें:

```bash
# CLI स्थापित करें
npm install -g muapi-cli

# एक बार प्रमाणित करें
muapi auth login

# Expose all MuApi models as MCP tools to your agent
muapi mcp serve
```

MCP सर्वर उन टूल को प्रदर्शित करता है जो `gemini-3-8-flash-tts` सहित प्रत्येक मॉडल के लिए सबमिट + पोल को लपेटते हैं। श्रेणी-विशिष्ट शॉर्टकट के लिए `muapi --help` देखें (`muapi image generate`, `muapi video from-image`, आदि)।
