Ergo On-Chain & Native Token API

healthy 3,962 Subscribers

Live on-chain data from the Ergo (ERG) blockchain via the public Ergo Platform explorer — clean JSON, no cache. Ergo is a proof-of-work cryptocurrency built on the extended-UTXO (eUTXO) model with first-class native tokens, Sigma-protocol smart contracts and storage rent — a distinctly different design from account-based chains. Read the network head (best block height, mining difficulty, miner reward); browse the most recent blocks with their miner, size, difficulty and reward; fetch a single block by header id; look up any address's confirmed ERG balance and every native token it holds; or resolve a native token's id, name, decimals, emission amount and description. Read live from Ergo, nothing stored. This is Ergo's own extended-UTXO chain, native-token and Autolykos-PoW layer — distinct from the Bitcoin, Decred, EOS, Internet Computer and other on-chain APIs and from price feeds.

Upbit API

Live spot market data from Upbit, South Korea's largest crypto exchange and one of the highest-volume venues in the world — served straight from its public API, no key, nothing cached. Get a market's price, 24h change, high/low, 24h volume and value and 52-week range (in Korean won, Bitcoin or Tether); rank every market for a quote currency by 24h trade value; list Upbit's trading pairs with their Korean and English names; and pull daily, weekly or monthly OHLC candles. Upbit's KRW prices are the reference for the "kimchi premium" — a distinct Korean-market venue, separate from other exchange feeds.

HTX API

Live spot market data from HTX (formerly Huobi), one of the longest-running centralised crypto exchanges and a leading venue in Asian markets. The ticker endpoint returns a symbol's 24h last price, open, high, low, best bid/ask, base and quote volume, trade count and change. The tickers endpoint returns the top symbols by 24h quote volume. The symbols endpoint searches HTX's spot trading pairs. Read live from HTX, nothing stored. This is HTX's own spot ticker and market layer — a distinct centralised-exchange venue, separate from other exchange feeds and from DEX, lending and oracle APIs.

KyberSwap API

Live DEX-aggregator swap quotes from KyberSwap, which routes a trade across every decentralised exchange and liquidity pool on a chain to find the best output. The quote endpoint prices a swap between two tokens on Ethereum, Arbitrum, Base, Optimism, Polygon or BNB Chain — it returns the amount received, the USD values in and out, the price impact, the estimated gas cost and the DEXs the route passes through. The tokens endpoint lists the supported tokens per chain. The chains endpoint lists supported chains. Read live from KyberSwap, nothing stored. This is KyberSwap's own multi-chain EVM swap-routing and best-price layer — distinct from single-DEX feeds and from Solana swap aggregators.

MEXC API

Live spot market data from MEXC, a top centralised crypto exchange known for listing the widest range of altcoins and new tokens first. The ticker endpoint returns a symbol's 24h last price, bid/ask, high/low, volume and change. The tickers endpoint returns the top symbols by 24h quote volume. The movers endpoint returns the biggest 24h gainers or losers among liquid pairs — the altcoin-momentum view MEXC is watched for. Read live from MEXC, nothing stored. This is MEXC's own spot ticker and altcoin-momentum layer — a distinct centralised-exchange venue, separate from other exchange feeds and from DEX, lending and oracle APIs.
