Hedera API

healthy 3,247 Subscribers

Live on-chain data from the Hedera network (HBAR), the enterprise public ledger built on hashgraph consensus, via the public Hedera Mirror Node. Hedera identifies every account, token and contract by a shard.realm.num id like 0.0.2 — not a hash address — and this API speaks that native form. Resolve an account's whole state: HBAR balance, the node or account it stakes to, whether it declines rewards and its pending reward, its auto-renew and token-association settings, memo and EVM nonce. Get the HTS tokens an account holds, each decimal-adjusted with token id and freeze/KYC status. Read any HTS token's details — name, symbol, decimals, total and max supply, treasury account and whether it's a fungible token or an NFT collection. Get the live HBAR supply, released and total. Live, no key, nothing stored. Distinct from the XRP Ledger, Stellar, TRON, Aptos, Algorand, Tezos, Cardano, Solana and EVM on-chain APIs and from price feeds — this is Hedera account state, staking, HTS-token holdings, token details and HBAR supply. Perfect for wallets, explorers, treasury, HTS-token and analytics apps.

Hedera Network & Nodes API

Read Hedera's network layer live from the public Hedera Mirror Node — no key. Hedera runs on a permissioned set of council-operated consensus nodes; the Hedera on-chain reader resolves account, token and HBAR-supply state, but it does not surface the node set, the live HBAR/USD exchange rate the network itself uses, or the current network fee schedule. This opens that. List the consensus nodes with their node id, account, operator description (e.g. "Hosted by Google | US"), current and min/max stake in HBAR, rewarded vs not-rewarded stake and whether they decline rewards; read the live HBAR↔USD rate the network pins for fee calculation — current and next period, with a derived USD-per-HBAR price — the protocol's own oracle rate, not a market ticker; and read the current network gas fee schedule per transaction type. Stake is reported in HBAR (1 HBAR = 100,000,000 tinybars). The network / validator / economics layer for Hedera explorers, staking dashboards, wallets and analytics. Distinct from the Hedera on-chain reader (account / token / supply), the HCS topic reader and the HTS token browser. Live from the mirror node; short cache only.

Hedera HTS Token & NFT API

Browse the Hedera Token Service (HTS) live from the public Hedera Mirror Node — no key. The Hedera on-chain reader resolves a single token's details by id and the tokens an account holds, but it cannot browse the token universe, list the serials inside an NFT collection, or list who holds a token. This opens that. Discover and filter HTS tokens — fungible vs NFT collection, search by name; list the minted serials inside any NFT collection, each with its current owner account and decoded per-serial metadata (often an IPFS or HCS pointer) and whether it has been burned; and list the holders of any token with their decimal-adjusted balances, largest first. Every token and account is a shard.realm.num id like 0.0.107597. The discovery and NFT layer for Hedera wallets, token explorers, NFT marketplaces and analytics. Distinct from the Hedera on-chain reader (per-token-id details and per-account holdings) and from the Hedera Consensus Service topic reader. Live from the mirror node; short cache only.

Hedera Topic API

Read the Hedera Consensus Service (HCS) live from the public Hedera mirror node — no key. HCS is Hedera's signature feature: a decentralized, ordered, timestamped message log that powers audit trails, supply-chain tracking, oracles and tokenization registries — the layer that account- and token-readers miss entirely. Look up any topic for its memo, admin/submit-key control, auto-renew and deleted state; read a topic's most recent messages, decoded from base64 to text, each with its consensus sequence number, timestamp and the account that paid to submit it; or discover the topics that are actively receiving messages right now. The consensus-messaging layer for Hedera wallets, explorers, dApps and auditors. Live from the mirror node; short cache only.

Meter API

Live EVM on-chain data for Meter (chain id 82) — the HotStuff-BFT proof-of-stake Layer-1 whose native gas token is MTR — served directly from public EVM JSON-RPC nodes with multi-node failover. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the MTR balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole MTR with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and analytics apps across the Meter ecosystem. Live keyless upstream. 5 endpoints.
