Blockchain Data API - Faster, Smarter, Better
We’ve made significant improvements to our Data API infrastructure
– and we’re excited to roll out new, faster endpoints that deliver better performance and richer data.
- Up to 2.5× faster API responses across key endpoints
- Smarter asset detection: now capturing more token types and balances
- Increased backend scalability for improved stability and uptime
📚 Migration Guide & Important changes in API
Deprecated Legacy Data API endpoints will be removed on June 30, 2025To ensure continued access and performance, all users must migrate to the new endpoints by this date.
The legacy endpoints will no longer be maintained or guaranteed to function. To take full advantage of these improvements, we encourage you to start using the new endpoints listed below.
