TON Blockchain API

degraded 4,506 Subscribers

Live on-chain data from The Open Network (TON / Toncoin), the layer-1 blockchain integrated with Telegram — no key, nothing cached, nothing stored. The network endpoint returns the latest masterchain block (the chain tip). The account endpoint returns any TON address's balance (in TON and nanoTON), account state and last-transaction reference. The transactions endpoint returns an address's most recent transactions with counterparties, value, fee and time. Addresses accept raw (0:.. / -1:..) or user-friendly (EQ.. / UQ..) form. This is live blockchain and network data straight from the public TON node API — distinct from the exchange-ticker, price and market APIs in the catalogue. Built for TON wallets, explorers, dashboards and on-chain analytics.

STON.fi API

Live data from STON.fi, the largest decentralised exchange on TON (The Open Network, the Telegram-native blockchain). The overview endpoint returns the DEX's current total value locked plus lifetime volume, wallets and trades. The pools endpoint returns the top liquidity pools by volume, APY or liquidity — each with its token pair, last price, base/quote volume and liquidity, LP token USD price and APY. The assets endpoint searches STON.fi's token registry by symbol and returns each token's live USD price, decimals and contract address. Read live from STON.fi, nothing stored. The only TON-native DeFi feed here — distinct from Ethereum, Solana and Sui DEX feeds — this is STON.fi's own TON DEX pool, volume/APY and token-pricing layer.

TAC API

Live TAC on-chain data via Blockscout. TAC is the TON Application Chain, an EVM layer that brings Ethereum apps to the TON ecosystem; gas and balances are in TAC. Network stats, gas prices, latest blocks, a block by height or hash, address detail with TAC balance, a transaction by hash, ERC-20 token metadata and a universal search across addresses, tokens, blocks and transactions. Real data, no key.

BTSE Exchange API

Live spot market data from BTSE, a global crypto exchange, served straight from its public order books — no key on the data, nothing cached, nothing stored. Look up any market for its last price, best bid/ask and spread, 24h high/low, 24h change and base/quote volume; rank every market for a quote currency by 24h turnover; list the tradable pairs with their base and quote; or pull live order-book depth with the running spread. Markets are addressed BASE-QUOTE (BTC-USD). This is the BTSE venue specifically — a distinct multi-fiat price feed that quotes against the US, Hong Kong, Canadian, New Zealand and Australian dollars plus the pound, euro, Swiss franc, yen and rupee as well as USDT/USDC, ideal for HKD/CAD/CHF/GBP/NZD price discovery and cross-venue arbitrage, separate from the USD/USDT-only exchange APIs in the catalogue.

EXMO Exchange API

Live spot market data from EXMO, a European/CIS crypto exchange, served straight from its public order books — no key on the data, nothing cached, nothing stored. Look up any market for its last price, best bid/ask and spread, 24h high/low/average and base/quote volume; rank every market for a quote currency by 24h turnover; list the tradable pairs with their base, quote and limits; or pull live order-book depth with the running spread. Markets are addressed BASE_QUOTE (BTC_UAH). This is the EXMO venue specifically — a distinct multi-fiat price feed that quotes against the Ukrainian hryvnia (UAH), Polish złoty (PLN), euro, Brazilian real and US dollar as well as USDT, ideal for UAH/PLN price discovery and Eastern-European-market arbitrage, separate from the USD/USDT-only exchange APIs in the catalogue.
