Aptos (APT) On-Chain API

healthy 3,935 Subscribers

Live on-chain data from the Aptos blockchain (APT), a high-throughput Move-based Layer 1, served straight from the official public Aptos fullnode REST API — no key, nothing cached. The account endpoint returns any address's state: its sequence number, authentication key, APT balance and how many on-chain resources it holds. The balance endpoint returns the balance of APT or any coin or fungible asset for an address, handling both the classic coin standard and the newer fungible-asset standard in one call. The resources endpoint lists the Move resource types an account holds — its coins, stores, staking and module data — the structural view of what lives at an address. The transactions endpoint returns the account's most recent transactions with the version, hash, entry function, success flag, gas used and time. The network endpoint returns the live chain state: chain id, the latest ledger version and block height, the epoch and the ledger timestamp. Everything is read live from the fullnode, nothing stored. This is the Aptos on-chain layer for any wallet, explorer, payments, gaming or analytics app. Distinct from the XRP Ledger, Stellar, TRON, EVM and Solana on-chain APIs and from price feeds — this is Aptos account state, balances, Move resources, transactions and ledger health. 5 endpoints, no key on our side.

Sui API

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.

Crypto Derivatives Exchanges API

Live ranking and directory of crypto derivatives venues — the platforms that run perpetual and futures markets — served from the public CoinGecko feed with no key and nothing cached. This is a venue-level view of the derivatives market, distinct from spot-exchange directories, per-contract open-interest feeds and single-exchange tickers: it ranks the derivatives platforms themselves. The exchanges endpoint returns the venues ranked by open interest (or by 24-hour volume), each with its open interest in BTC, 24-hour derivatives volume in BTC, the number of perpetual and futures pairs it lists, its country and the year it was established — so one call tells you who the biggest derivatives venues are and how concentrated open interest is. The exchange endpoint returns a single venue's full profile by id. The list endpoint returns every derivatives-exchange id and name for lookup and autocomplete. Everything is read live from CoinGecko on each request, nothing stored beyond a short protective cache. Ideal for derivatives dashboards, open-interest and market-structure analytics, venue comparison and trading tools. Live, no key. 3 endpoints. For per-contract funding and open-interest history use a derivatives or open-interest API.

Crypto.com Exchange API

Live spot market data from the Crypto.com Exchange, one of the largest global retail crypto venues and the heart of the CRO ecosystem, served straight from its public API with no key and nothing cached. The ticker endpoint returns a market's last price, best bid and ask, the spread, 24-hour high and low, 24-hour change and base and quote volume. The tickers endpoint returns every spot market for a quote currency ranked by 24-hour quote volume, so one call gives you the most-traded pairs on the venue. The instruments endpoint lists the tradable spot pairs with their price and quantity tick sizes and decimal precision. The book endpoint returns live order-book depth — every bid and ask level with price, amount and order count, plus the best bid/ask and spread. Everything is read live from Crypto.com on each request, nothing stored; perpetual contracts are excluded so you get clean spot data. A distinct global venue, separate from the other exchange feeds on the marketplace. Ideal for trading bots, price tickers, arbitrage scanners, portfolio trackers and market dashboards. Live, no key. 4 spot endpoints. For perpetuals or candles use a derivatives or OHLC API.

Crypto Trending API

What the crypto market is searching for right now, served live from the public CoinGecko trending feed with no key. This is hype and attention data — distinct from market-cap rankings, exchange tickers and DeFi feeds — surfacing the coins, NFT collections and categories with the biggest spike in search interest over the last 24 hours. The coins endpoint returns the trending coins ranked by search popularity, each with its live USD price, 24-hour change, market cap, 24-hour volume, market-cap rank and BTC price. The nfts endpoint returns the trending NFT collections with floor price (native and display), 24-hour floor change and 24-hour volume. The categories endpoint returns the trending narratives and sectors with market cap, volume and 24-hour change. Trending means ranked by CoinGecko search popularity, so rank 1 is the single most-searched asset of the moment — exactly the signal traders, bots and dashboards use to catch a move early. Read live from CoinGecko, nothing stored beyond a short protective cache. Ideal for crypto dashboards, trading bots, sentiment and hype trackers, and discovery feeds. Live, no key. 3 trending endpoints. For full price history use an OHLC or exchange API.
