Live on-chain data from the Tezos blockchain (XTZ), a self-amending liquid-proof-of-stake Layer 1, served from the public TzKT indexer API — no key, nothing cached. The account endpoint returns any address's state: its XTZ balance, account type, the baker it delegates to, its staked balance, transaction count and first-activity date. The tokens endpoint returns the FA1.2 and FA2 token balances an address holds, with the token contract, symbol and decoded amount. The operations endpoint returns the account's most recent transactions with the counterparty, amount, status and time. The network endpoint returns the live chain state: the head block level, the current cycle, the active protocol and the total XTZ supply. Everything is read live from TzKT, nothing stored. This is the Tezos on-chain layer for any wallet, explorer, baking, NFT or analytics app. Distinct from the XRP Ledger, Stellar, TRON, Aptos, Algorand, EVM and Solana on-chain APIs and from price feeds — this is Tezos account state, delegation, token balances, operations and ledger health. 4 endpoints, no key on our side.

Live on-chain data from the Algorand blockchain (ALGO), a fast carbon-negative pure-proof-of-stake Layer 1, served straight from the public AlgoNode indexer and algod APIs — no key, nothing cached. The account endpoint returns any address's state: its ALGO balance, participation status (online/offline for staking), pending rewards, the Algorand Standard Assets (ASAs) it holds with their amounts, and how many apps it has created. The asset endpoint returns the on-chain registry entry for any ASA — its name, unit, decimals, total supply, creator and URL, so you can resolve USDC, USDt and thousands of tokens. The transactions endpoint returns the account's most recent transactions with the type, counterparty, amount, fee, round and time. The network endpoint returns the live chain state: the last round, the round time, and the total and online ALGO supply. Everything is read live from AlgoNode, nothing stored. This is the Algorand on-chain layer for any wallet, explorer, payments, DeFi or analytics app. Distinct from the XRP Ledger, Stellar, TRON, Aptos, EVM and Solana on-chain APIs and from price feeds — this is Algorand account state, ASA holdings, asset registry, transactions and ledger health. 4 endpoints, no key on our side.

Live-On-Chain-Daten von der Aptos-Blockchain (APT), einer hochdurchsatzfähigen Move-basierten Layer 1, direkt von der offiziellen öffentlichen Aptos-Fullnode-REST-API bereitgestellt – kein Key, nichts gecached. Der Account-Endpunkt gibt den Zustand einer beliebigen Adresse zurück: ihre Sequenznummer, den Authentifizierungs-Key, den APT-Saldo und wie viele On-Chain-Ressourcen sie hält. Der Balance-Endpunkt gibt den Saldo von APT oder einer beliebigen Coin oder eines fungiblen Assets für eine Adresse zurück und verarbeitet sowohl den klassischen Coin-Standard als auch den neueren Fungible-Asset-Standard in einem Aufruf. Der Resources-Endpunkt listet die Move-Ressourcentypen auf, die ein Account hält – seine Coins, Stores, Staking- und Moduldaten – die strukturelle Ansicht dessen, was sich an einer Adresse befindet. Der Transactions-Endpunkt gibt die letzten Transaktionen des Accounts mit Version, Hash, Entry-Funktion, Erfolgsflag, verbrauchtem Gas und Zeit zurück. Der Network-Endpunkt gibt den Live-Chain-Status zurück: Chain-ID, die neueste Ledger-Version und Blockhöhe, die Epoche und den Ledger-Zeitstempel. Alles wird live von der Fullnode gelesen, nichts gespeichert. Dies ist die Aptos-On-Chain-Schicht für jede Wallet, Explorer, Zahlungen, Gaming- oder Analyse-App. Abgrenzung zu den XRP Ledger-, Stellar-, TRON-, EVM- und Solana-On-Chain-APIs sowie zu Preis-Feeds – dies ist der Aptos-Account-Status, Salden, Move-Ressourcen, Transaktionen und Ledger-Health. 5 Endpunkte, kein Key auf unserer Seite.
