# 💋 Realistic Lipsync Animation API (Pixverse Lipsync)

## Overview
The Realistic Lipsync Animation API by Pixverse Lipsync allows developers to generate precise and high-quality lipsync animations from audio files. This AI-powered tool seamlessly synchronizes audio with video, ensuring a realistic and engaging visual experience for viewers.

## Features
- High-quality lipsync synchronization
- Fast and efficient processing
- Easy integration with various applications
- Asynchronous processing for better performance
- Minimal lag with real-time applications

## Use Cases
Here are some practical examples of how the Realistic Lipsync Animation API can be used across different industries:

1. **Film and Animation**: Enhance animated characters by syncing their lip movements with voice-overs, creating a more lifelike experience.
2. **Education**: Create engaging educational videos where the teacher's video is synced with the lesson's audio, ensuring clarity and coherence in virtual learning environments.
3. **Advertising**: Produce compelling video ads with voiceovers that match the on-screen presenter’s lip movements, delivering a more professional and polished message.
4. **Gaming**: Integrate with interactive video games to ensure characters' lip movements match the dialogue, providing a more immersive experience.
5. **Social Media Content Creation**: Empower content creators to produce professional-grade lip-synced videos quickly, enhancing their social media presence.

## Pricing
- **Pay As You Go (PAYG)**: You only pay for what you use.
- **$0.05 per second of output video**
- **GET requests** to check prediction status (`GET /api/v1/magicapi/realistic-lipsync-animation-api-pixverse-lipsync/predictions/{id}`) are free and don't count toward API unit usage.

## API Documentation

### Base URL
All API requests should be made to:
```
https://prod.api.market/api/v1/magicapi/realistic-lipsync-animation-api-pixverse-lipsync
```

### Authentication
Authentication is handled via API key. Include your API key in the request header:
```
x-api-market-key: YOUR_API_MARKET_KEY
```

### Asynchronous Processing
**IMPORTANT**: This API uses asynchronous processing for predictions. The typical flow is:
1. Submit a prediction request to the POST endpoint.
2. Receive a prediction ID in the response.
3. Poll the GET endpoint with the prediction ID to check status.
4. Continue polling until the prediction is complete.

The processing time varies depending on the complexity of the request. Your code should implement:
- A polling interval of 1 second between status checks
- A maximum timeout of 600 seconds (10 minutes)
- Status checking logic that continues while status is "starting" or "processing"
- Result handling when status becomes "succeeded"
- Error handling when status becomes "failed" or timeout is reached

### Endpoints

#### Create Prediction
**POST /api/v1/magicapi/realistic-lipsync-animation-api-pixverse-lipsync/predictions**

Create a new prediction.
```bash
curl -X POST "https://prod.api.market/api/v1/magicapi/realistic-lipsync-animation-api-pixverse-lipsync/predictions" \

    "video": "https://blog.api.market/wp-content/uploads/2026/01/woman-cafe-input-api-market.mp4"
  }
}'
```

#### cURL Example
```bash
# Step 1: Create a prediction
curl -X POST "https://prod.api.market/api/v1/magicapi/realistic-lipsync-animation-api-pixverse-lipsync/predictions" \
-H "Content-Type: application/json" \
-H "x-api-market-key: YOUR_API_MARKET_KEY" \
-d '{
  "version": "3ca6d73f4fb9e1d77a4b6e14f8998ee18926e4dc462838e31fa2bb5e662c1e2c",
  "input": {
    "audio": "https://blog.api.market/wp-content/uploads/2026/01/every-person.mp3",
    "video": "https://blog.api.market/wp-content/uploads/2026/01/woman-cafe-input-api-market.mp4"
  }
}'

# Response will contain a prediction ID like:
# {"id": "abcd1234", "status": "starting"}

# Step 2: Check prediction status (replace abcd1234 with the actual ID)
curl -X GET "https://prod.api.market/api/v1/magicapi/realistic-lipsync-animation-api-pixverse-lipsync/predictions/abcd1234" \
-H "x-api-market-key: YOUR_API_MARKET_KEY"

# Note: You need to repeatedly poll this endpoint manually until status is "succeeded"
```
