Best Practices
| Best Practice | Description |
|---|---|
| Commitment Levels | Use appropriate commitment levels: processed (fastest), confirmed (balanced), finalized (most reliable) |
| Rate Limiting | Implement retry logic and respect rate limits. Public endpoints: 100 req/s, Private: 1000+ req/s |
| Batch Requests | Use batch requests when possible to improve efficiency and reduce API calls |
| Caching | Cache frequently accessed data to reduce API calls and improve performance |
