STON.fi API

degraded 3,243 Subscribers

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.

Cetus API

Live data from Cetus, the largest concentrated-liquidity (CLMM) DEX on Sui, which runs most of Sui's on-chain swap volume across thousands of pools. The pools endpoint returns the top pools by TVL, volume or APR — each with its token pair, fee tier, total liquidity, 24h volume and fees, the fee APR and reward APR, and the current price. The pool endpoint returns one pool's full state by address. The search endpoint finds pools by token symbol. Read live from Cetus, nothing stored. This is Cetus's own Sui CLMM pool, TVL/volume/APR and pricing layer — distinct from Ethereum and Solana DEX feeds, lending, staking and oracle APIs, and the only Sui-native DeFi feed here.

Raydium API

Live data from Raydium, the largest automated-market-maker DEX on Solana, whose standard (AMM) and concentrated-liquidity (CLMM) pools route most of Solana's on-chain swap volume. The overview endpoint returns the protocol's total value locked and 24h volume. The pools endpoint returns the top pools by liquidity, volume, APR or fees — each with its pair, type, price, TVL, 24h volume, fee APR and fee rate. The pool endpoint returns one pool's full state by id, including weekly and monthly volume and the CLMM price range. The price endpoint returns the live USD price of one or more SPL tokens by mint address, with symbol shortcuts for SOL, RAY, USDC and more. Read live from Raydium, nothing stored. This is Raydium's own Solana AMM/CLMM pool, TVL/volume/APR and token-pricing layer — distinct from Ethereum AMM feeds (Balancer, Curve), order-book/perps DEX feeds and swap aggregators.

Balancer API

Live data from Balancer, a leading multi-chain decentralised AMM whose programmable liquidity pools (weighted, stable, gyro, boosted) power swaps and yield across Ethereum, Arbitrum, Base, Polygon, Avalanche, Gnosis, Optimism and more. The pools endpoint returns the top pools by TVL on a chain — each with its type, total liquidity, 24h volume and fees, total APR (with a yield/swap/staking breakdown) and constituent tokens. The pool endpoint returns one pool's full state by id, including swap and holder counts and the full APR breakdown. The token endpoint returns a token's live Balancer price plus its symbol, name and decimals. The tokens endpoint searches the token registry by symbol or name. Read live from Balancer, nothing stored. This is Balancer's own programmable-pool AMM, TVL/volume/APR and token-pricing layer — distinct from constant-product DEX feeds, Curve's stableswap and order-book or perps DEX feeds.
