Sui API

healthy 4,117 Subscribers

Live on-chain data from Sui (SUI), the high-throughput Layer 1 from Mysten Labs built on the Move language and an object-centric model, via a public Sui full-node JSON-RPC endpoint. Unlike account- or UTXO-based chains, on Sui everything an address owns is a typed Move object. Resolve an address's SUI balance together with every coin type it holds and how many distinct coins it owns. Read any coin type's metadata — its name, symbol, decimals and description — and its total on-chain supply. List the Move objects an address owns, each with its object id and fully-qualified type, the native unit of Sui ownership. Read the live chain state — the chain identifier, the current epoch, the latest checkpoint, the total transaction-block count, the reference gas price and the active validator count. Live, no key, nothing stored. Distinct from the XRP Ledger, Stellar, TRON, Aptos, Algorand, Tezos, Cardano, Hedera, Kaspa, Cosmos, Solana and EVM on-chain APIs and from price feeds — this is Sui's object-model account state, coins, owned objects and chain economics. Perfect for wallets, explorers and analytics apps.

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.

Chain Stats API

Live blockchain network statistics across 18 chains, from the public Blockchair feed. Get one network's full stats — price, market cap and dominance, block height, 24h transactions, circulating supply, difficulty, hashrate, mempool size and average fee; compare the major chains side by side, ranked by market cap; and read a chain's mempool congestion (pending transactions, size and fees). A multi-chain network-stats layer — distinct from single-coin price feeds and Bitcoin-only on-chain APIs: it answers how each blockchain is performing right now and how they compare. Live, with a 10-minute upstream cache.

Dash On-Chain API

Live on-chain data from the Dash (DASH) blockchain — a payments-focused cryptocurrency — via the public Dash Insight explorer, clean JSON and no cache. Dash uses X11 proof-of-work plus a second tier of collateralised masternodes that power InstantSend (near-instant locked payments) and ChainLocks, and an on-chain treasury that funds proposals. Read the chain state (block height, difficulty, peer connections, protocol version and relay fee); fetch a block by height or hash; look up an address's DASH balance, total received and sent and transaction count; or resolve a transaction's block, value, fee, input/output counts and its InstantSend lock status. Read live from Dash, nothing stored. This is Dash's own X11, masternode-tier and InstantSend ledger — distinct from the Bitcoin, Decred, Ergo, Nervos and other on-chain APIs and from price feeds.

Conflux On-Chain API

Live on-chain data from the Conflux (CFX) network — a high-throughput Layer-1 that orders blocks with the Tree-Graph DAG consensus (not a single chain) and runs two spaces: the native Core space (cfx: addresses) and an EVM-compatible eSpace. Served live from a public Conflux Core-space JSON-RPC node as clean JSON. Conflux is distinctive for its storage-collateral model and a built-in proof-of-stake interest rate. Read the chain state (chain id, current epoch, block number, latest-finalized epoch, pending-tx count and the PoS interest rate); the supply (circulating, issued, staked and storage-collateral CFX); a block (the pivot block of an epoch) by epoch number or hash; or a Core-space address's CFX balance and staked balance. Read live from Conflux, nothing cached. This is Conflux's own Tree-Graph, storage-collateral and PoS layer — distinct from the Bitcoin, Decred, Ergo, Nervos and other on-chain APIs and from price feeds.
