Blockchain Data API - Faster, Smarter, Better
May 29th, 2025
We’ve made significant improvements to our Data API infrastructure, delivering new, faster endpoints with improved performance, richer data, and higher scalability.
- Up to 2.5× faster API responses across key endpoints
- Smarter asset detection — capturing more token types and balances
- Increased backend scalability for improved stability and uptime
Migration Guide & Important Changes
Deprecated Legacy Data API endpoints will be removed on June 30, 2025
To ensure uninterrupted service, 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 the performance improvements, start using the updated endpoints below.
