The TON API documentation provides developers with the tools to interact programmatically with The Open Network blockchain. It covers fetching account information, calling smart contract get methods for precise data retrieval, and fetching account transactions. The API utilizes HTTP-based JSON-RPC endpoints, with TON Center being a recommended provider. This interface is essential for building decentralized applications that need to read and interact with the TON blockchain efficiently.
