const customAuctionHouse = "E8cU1WiRWjanGxmn96ewBgk9vPTcL6AEZ1t6F6fkgUWe";

// List with custom auction house
await agent.methods.listMagicEdenNFT({
  tokenMint: "NFT_MINT",
  tokenAccount: "TOKEN_ACCOUNT",
  price: 1.5,
  auctionHouseAddress: customAuctionHouse
});

// Earn referral fees on sales
const referralAddress = "YOUR_REFERRAL_ADDRESS";

await agent.methods.listMagicEdenNFT({
  tokenMint: "NFT_MINT",
  tokenAccount: "TOKEN_ACCOUNT", 
  price: 1.5,
  sellerReferral: referralAddress // Seller referral
});

await agent.methods.bidOnMagicEdenNFT({
  tokenMint: "NFT_MINT",
  price: 1.2,
  buyerReferral: referralAddress // Buyer referral
});

Advanced Filtering

// Filter listings by price range and sort options
const expensiveListings = await agent.methods.getMagicEdenCollectionListings({
  collectionSymbol: "degods",
  min_price: 50.0, // Only NFTs above 50 SOL
  max_price: 1000.0,
  sort: "listPrice",
  sort_direction: "desc", // Most expensive first
  limit: 10
});

// Recently listed items
const recentListings = await agent.methods.getMagicEdenCollectionListings({
  collectionSymbol: "solana_monkey_business",
  sort: "updatedAt",
  sort_direction: "desc", // Most recent first
  limit: 20
});

Error Handling

Common Error Scenarios

try {
  const result = await agent.methods.listMagicEdenNFT({...});
} catch (error) {
  if (error.message.includes("Magic Eden API key is required")) {
    // Handle missing API key
  } else if (error.message.includes("Invalid response")) {
    // Handle API response errors
  } else if (error.message.includes("insufficient funds")) {
    // Handle insufficient balance
  }
}

Error Types

1. Authentication Errors

   • Missing or invalid API key
   • Expired authentication

2. Validation Errors

   • Invalid token mint address
   • Invalid price (negative or zero)
   • Missing required parameters

3. Transaction Errors

   • Insufficient SOL balance
   • NFT not owned by wallet
   • Network congestion

4. API Errors

   • Rate limiting
   • Service unavailable
   • Invalid collection symbol

Best Practices

1. Listing Strategy

// Check collection floor price before listing
const stats = await agent.methods.getMagicEdenCollectionStats({
  collectionSymbol: "collection_name"
});

const floorPrice = stats.stats.floorPrice;
const listPrice = floorPrice * 0.95; // List 5% below floor

await agent.methods.listMagicEdenNFT({
  tokenMint: "NFT_MINT",
  tokenAccount: "TOKEN_ACCOUNT",
  price: listPrice
});

2. Bidding Strategy

// Research recent sales before bidding
const listings = await agent.methods.getMagicEdenCollectionListings({
  collectionSymbol: "collection_name",
  sort: "listPrice",
  sort_direction: "asc",
  limit: 10
});

// Bid on the cheapest listing
const cheapestListing = listings.listings[0];
const bidPrice = cheapestListing.price * 0.9; // Bid 10% below asking

await agent.methods.bidOnMagicEdenNFT({
  tokenMint: cheapestListing.tokenMint,
  price: bidPrice
});

3. Market Analysis

// Compare popular collections
const popular = await agent.methods.getPopularMagicEdenCollections({
  timeRange: "7d"
});

// Analyze each collection
for (const collection of popular.collections) {
  const stats = await agent.methods.getMagicEdenCollectionStats({
    collectionSymbol: collection.symbol,
    timeWindow: "7d"
  });
  
  console.log(`${collection.name}: Floor ${stats.stats.floorPrice} SOL, Volume ${stats.stats.volumeAll} SOL`);
}

Security Considerations

1. NFT Ownership Verification

// Always verify you own the NFT before listing
// The tokenAccount must be owned by your wallet

2. Price Validation

// Implement price checks to avoid listing errors
const minPrice = 0.001; // Minimum 0.001 SOL
const maxPrice = 1000; // Maximum 1000 SOL

if (price < minPrice || price > maxPrice) {
  throw new Error("Price out of acceptable range");
}

3. API Key Security

// Never expose API keys in client-side code
// Use environment variables for API key storage
process.env.MAGIC_EDEN_API_KEY

Rate Limits & Performance

API Rate Limits

• With API Key: Higher rate limits for authenticated requests
• Without API Key: Limited requests for public endpoints
• Recommended: Use API key for production applications

Optimization Tips

// Batch collection data requests
const collections = ["degods", "okay_bears", "degenape"];
const statsPromises = collections.map(symbol => 
  agent.methods.getMagicEdenCollectionStats({ collectionSymbol: symbol })
);
const allStats = await Promise.all(statsPromises);

Popular Collection Symbols

Top Solana NFT Collections

• degods - DeGods
• okay_bears - Okay Bears
• degenape - Degenerate Ape Academy
• solana_monkey_business - Solana Monkey Business

Finding Collection Symbols

// Use popular collections endpoint to discover symbols
const popular = await agent.methods.getPopularMagicEdenCollections({
  timeRange: "7d"
});

// Each collection object contains the symbol field
popular.collections.forEach(collection => {
  console.log(`Name: ${collection.name}, Symbol: ${collection.symbol}`);
});

Integration Examples

Trading Bot Example

// Simple arbitrage detection
async function findArbitrageOpportunities() {
  const collections = ["degods", "okay_bears"];
  
  for (const symbol of collections) {
    const stats = await agent.methods.getMagicEdenCollectionStats({
      collectionSymbol: symbol
    });
    
    const listings = await agent.methods.getMagicEdenCollectionListings({
      collectionSymbol: symbol,
      limit: 5,
      sort: "listPrice",
      sort_direction: "asc"
    });
    
    const cheapest = listings.listings[0];
    const floorPrice = stats.stats.floorPrice;
    
    // If cheapest listing is significantly below floor
    if (cheapest.price < floorPrice * 0.8) {
      console.log(`Opportunity found: ${symbol} listed at ${cheapest.price} SOL (floor: ${floorPrice} SOL)`);
    }
  }
}

Portfolio Tracker Example

// Track your listed NFTs
async function trackListings(ownedNfts: string[]) {
  for (const tokenMint of ownedNfts) {
    // Check if NFT is listed by looking through collection listings
    // This requires knowing which collection each NFT belongs to
  }
}
