Best Practices for Implementation

Rate Limiting
- Implement request throttling (max 5 requests/sec)
- Cache frequent queries locally
Error Handling
- Retry transient failures (5xx errors)
- Implement exponential backoff
Data Freshness
- Balance real-time updates with performance
- Consider webhooks for critical changes

FAQ Section

Q: How frequently is asset data updated?

A: Our systems refresh blockchain data every 15 minutes, with critical updates propagating within 2 minutes.

Q: Can I query multiple wallets simultaneously?

A: Yes, but each wallet requires separate API calls. We recommend parallel processing for bulk operations.

Q: What's the maximum response size for asset lists?

A: Responses are paginated with a default limit of 100 items per page. Use cursor-based pagination for large collections.

Q: How do I handle private NFTs?

A: Configure appropriate privacy settings through our developer dashboard before querying sensitive assets.

Performance Optimization Tips

Selective Field Retrieval
```
{
  "fields": ["name", "image_url"]
}
```
Local Caching Strategies
- Cache immutable NFT metadata indefinitely
- Refresh ownership data hourly
Connection Pooling
- Maintain persistent API connections
- Reuse authenticated sessions
