About TON Center
TON Center offers HTTP APIs for the TON blockchain: direct liteserver access, indexed data, transaction emulation, real-time streams and validator efficiency data. The TON documentation uses its API v2 and v3 as the reference examples for reading chain data.
The docs' comparison table explains the difference: v2 relays requests to liteservers, while v3 is an indexer with its own database for richer queries. Both are open source and can be self-hosted, and you can request an API key through the documented process.
Highlights
- v2 relays to liteservers, v3 is an indexer
- Open source and self-hostable
- Transaction emulation and real-time streams
