HTTP API

Getting Started

This documentation provides a comprehensive guide to using the TON HTTP API, including API endpoints, request and response formats, and error handling. Whether you're building a new application or integrating with an existing one, this documentation will help you get started with the TON HTTP API quickly and efficiently.

Get Address Information

get

Get basic information about the address: balance, code, data, last_transaction_id.

Authorizations
Query parameters
addressstringRequired

  "ok": true,
  "result": "text",
  "error": "text",
  "code": 1

Get Extended Address Information

get

Similar to previous one but tries to parse additional information for known contract types. This method is based on tonlib's function getAccountState. For detecting wallets we recommend to use getWalletInformation.

Get Wallet Information

get

Retrieve wallet information. This method parses contract state and currently supports more wallet types than getExtendedAddressInformation: simple wallet, standart wallet, v3 wallet, v4 wallet.
