TON Center provides fast and reliable HTTP APIs for interacting with The Open Network, allowing developers to easily access blockchain data for use in wallets, explorers, automation tools, and more. Because TON nodes use a binary protocol (ADNL), the HTTP API acts as a bridge, translating requests into compatible formats through two main implementations.

​
API Versions

  • v2 – TON HTTP API
    Real-time access to blockchain state using tonlibjson and Liteservers.
  • v3 – TON Indexer
    PostgreSQL-based indexer that provides stable and queryable access to structured blockchain data.
Free access is limited to 1 request per second. To increase limits, request an API key via @toncenter on Telegram or follow this guide.

Self-Hosted

Run the APIs on your own infrastructure:
Running your own infra means you’ll need quite powerful hardware. For example, the minimun requirements for a liteserver are at least 16-core CPU, 128 GB RAM, 1 TB NVMe SSD, and 1 Gbps connection.
