## API Methods

### Live Streaming Coins

```javascript
// Get currently live coins with pagination
const liveCoins = await client.getCurrentlyLiveCoins({
  offset: 0,        // Skip items (default: 0)
  limit: 60,        // Items to return (default: 60, max: 60)
  sort: 'currently_live', // Sort field
  order: 'DESC',    // Sort order (ASC/DESC)
  includeNsfw: false // Include NSFW content
});
```

### Stream Clips and Highlights

```javascript
// Get complete stream recordings
const completeStreams = await client.getCompleteStreams(mintId, 20);

// Get highlight clips
const highlights = await client.getHighlightClips(mintId, 20);

// Generic clip retrieval
const clips = await client.getStreamClips(mintId, {
  limit: 20,
  clipType: 'COMPLETE' // or 'HIGHLIGHT'
});
```

### Livestream Status

```javascript
// Check if creator is approved for livestreaming
const approval = await client.checkCreatorLivestreamApproval(mintId);

// Get current livestream status
const livestream = await client.getCurrentLivestream(mintId);
```

### Chat and Social

```javascript
// Get chat invite information
const invites = await client.getCoinChatInvites(mintId);
```

### Market Data

```javascript
// Get current SOL price
const solPrice = await client.getSolPrice();

// Get platform flags and configuration
const flags = await client.getPlatformFlags();
```

### Download Clips

```javascript
// Download a highlight clip (MP4)
const clip = { /* StreamClip object */ };
const result = await client.downloadHighlightClip(clip, './downloads/clip.mp4', {
  onProgress: (progress, downloaded, total) => {
    console.log(`Download: ${progress.toFixed(1)}%`);
  }
});

// Download a complete stream (HLS) - requires ffmpeg
const completeResult = await client.downloadCompleteStream(clip, './downloads/complete.mp4', {
  onProgress: (progress, currentTime, totalTime) => {
    console.log(`Progress: ${progress.toFixed(1)}%`);
  },
  ffmpegPath: 'ffmpeg' // or path to ffmpeg executable
});

// Download with automatic format detection
const autoResult = await client.downloadClip(clip, './downloads/auto.mp4');

// Download multiple clips
const results = await client.downloadHighlightClips(clips, './downloads/', {
  concurrency: 3, // Download 3 clips simultaneously
  filenameGenerator: (clip, index) => `clip-${index + 1}.mp4`
});

// Download thumbnail
const thumbResult = await client.downloadThumbnail(clip, './downloads/thumb.jpg');

// Get download information
const info = await client.getClipDownloadInfo(clip);
console.log(`Format: ${info.format}, Size: ${info.estimatedSize} bytes`);
```

## Client Configuration

```javascript
import { createClient } from 'pumpfun-api';

const client = createClient({
  timeout: 30000, // Request timeout in milliseconds
  headers: {
    'User-Agent': 'My-App/1.0'
  }
});
```

## Data Structures

### Live Coin Object

```javascript
{
  mint: "string",              // Solana token mint address
  name: "string",              // Coin name
  symbol: "string",            // Ticker symbol
  description: "string",       // Coin description
  image_uri: "string",         // IPFS image URL
  market_cap: 12345.67,        // USD market cap
  is_currently_live: true,     // Live streaming status
  livestream_title: "string",  // Livestream title
  creator: "string",           // Creator wallet address
  // ... many more fields
}
```

### Stream Clip Object

```javascript
{
  clipId: "string",
  sessionId: "string",
  startTime: "2023-10-18T15:30:00Z",
  endTime: "2023-10-18T16:30:00Z",
  duration: 3600,              // Duration in seconds
  playlistUrl: "string",       // HLS playlist URL (for COMPLETE clips)
  mp4Url: "string",            // Direct MP4 URL (for HIGHLIGHT clips)
  thumbnailUrl: "string",      // Thumbnail image URL
  clipType: "COMPLETE" | "HIGHLIGHT",
  createdAt: "2023-10-18T16:45:00Z"
}
```

## Downloading Clips

### Prerequisites

- **MP4 Downloads**: No additional requirements
- **HLS Downloads**: Requires [ffmpeg](https://ffmpeg.org/) to be installed
  - Ubuntu: `sudo apt-get install ffmpeg`
  - macOS: `brew install ffmpeg`
  - Windows: Download from [ffmpeg.org](https://ffmpeg.org/download.html)

### Download Types

The package supports two types of downloads:

1. **Highlight Clips (HIGHLIGHT)**: Direct MP4 downloads
2. **Complete Streams (COMPLETE)**: HLS streams converted to MP4 using ffmpeg

### Download Options

```javascript
const options = {
  onProgress: (progress, downloaded, total) => {
    // Progress callback (0-100%)
    console.log(`Progress: ${progress.toFixed(1)}%`);
  },
  timeout: 300000, // Download timeout in milliseconds
  ffmpegPath: 'ffmpeg' // Path to ffmpeg executable (for HLS downloads)
};
```

### Download Results

```javascript
{
  success: true,
  path: '/path/to/downloaded/file.mp4',
  size: 1234567, // File size in bytes
  clip: { /* Original clip data */ }
}
```

### Batch Downloads

```javascript
// Download multiple clips with concurrency control
const results = await client.downloadHighlightClips(clips, './downloads/', {
  concurrency: 3, // Max simultaneous downloads
  filenameGenerator: (clip, index) => {
    // Custom filename generation
    return `clip-${index + 1}-${clip.clipId}.mp4`;
  },
  onProgress: (progress, downloaded, total) => {
    // Progress for individual downloads
  }
});

// Check results
results.forEach(result => {
  if (result.success) {
    console.log(`Downloaded: ${result.path}`);
  } else {
    console.log(`Failed: ${result.error}`);
  }
});
```

## Examples

### Basic Usage

```javascript
import { createClient } from 'pumpfun-api';

const client = createClient();

// Get live coins and their details
const liveCoins = await client.getCurrentlyLiveCoins({ limit: 10 });

for (const coin of liveCoins) {
  console.log(`${coin.name} (${coin.symbol})`);
  console.log(`Market Cap: $${coin.market_cap.toLocaleString()}`);
  console.log(`Live: ${coin.is_currently_live}`);

  if (coin.is_currently_live) {
    const clips = await client.getHighlightClips(coin.mint, 3);
    console.log(`Clips: ${clips.clips.length} available`);
  }
}
```

### Advanced Usage with Pagination

```javascript
// Get all live coins with pagination
let allCoins = [];
let offset = 0;
const limit = 60;

while (true) {
  const coins = await client.getCurrentlyLiveCoins({ offset, limit });

  if (coins.length === 0) break;

  allCoins = allCoins.concat(coins);
  offset += limit;
}

// Filter high market cap tokens
const highCapTokens = allCoins
  .filter(coin => coin.market_cap > 100000)
  .sort((a, b) => b.market_cap - a.market_cap);
```

### Error Handling

```javascript
import { createClient } from 'pumpfun-api';

const client = createClient({ timeout: 10000 });

try {
  const liveCoins = await client.getCurrentlyLiveCoins();
  console.log(`Found ${liveCoins.length} live coins`);
} catch (error) {
  if (error.message.includes('timeout')) {
    console.error('Request timed out');
  } else if (error.message.includes('HTTP error')) {
    console.error('API error:', error.message);
  } else {
    console.error('Unexpected error:', error);
  }
}
```

### Download Example

```javascript
import { createClient } from 'pumpfun-api';

const client = createClient();

async function downloadTokenClips(mintId) {
  try {
    // Get highlight clips
    const { clips } = await client.getHighlightClips(mintId, 5);

    console.log(`Found ${clips.length} clips, downloading...`);

    // Download each clip with progress tracking
    for (const [index, clip] of clips.entries()) {
      try {
        const result = await client.downloadHighlightClip(
          clip,
          `./downloads/clip-${index + 1}.mp4`,
          {
            onProgress: (progress) => {
              process.stdout.write(`\rClip ${index + 1}: ${progress.toFixed(1)}%`);
            }
          }
        );

        console.log(`\n✅ Downloaded: ${result.path}`);
        console.log(`   Size: ${(result.size / 1024 / 1024).toFixed(2)} MB`);

      } catch (error) {
        console.log(`\n❌ Failed to download clip ${index + 1}: ${error.message}`);
      }
    }

    // Batch download thumbnails
    const thumbnailResults = await client.downloadHighlightClips(
      clips.map(clip => ({ ...clip, mp4Url: clip.thumbnailUrl })),
      './downloads/thumbnails/',
      {
        concurrency: 5,
        filenameGenerator: (clip, index) => `thumb-${index + 1}.jpg`
      }
    );

    console.log(`\nDownloaded ${thumbnailResults.filter(r => r.success).length} thumbnails`);

  } catch (error) {
    console.error('Download failed:', error.message);
  }
}
```
