Tezos (XTZ) On-Chain API

healthy 3,747 Subscribers

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.

Etherlink Chain API

Live on-chain data for Etherlink — a Tezos-secured EVM Layer 2 — via its public Blockscout explorer (no wallet, no key). The stats endpoint returns chain-wide totals (blocks, transactions, addresses, average block time, gas used); gas gives the current gas-price oracle (slow/average/fast). Blocks lists the latest blocks, and a single block resolves by height or by hash with its transaction count, gas, miner and timestamp. The address endpoint returns any account's XTZ balance, nonce, contract flag and token holdings; transaction resolves a tx by hash with its from/to, value in XTZ, fee, status and block. The token endpoint returns an ERC-20 token's metadata (name, symbol, decimals, total supply, holders) by contract address, and search runs a universal lookup across addresses, tokens, blocks and transactions. Gas, balances, values and fees are denominated in XTZ, the native coin. Real on-chain data straight from the explorer, refreshed every call — no key. 9 endpoints. For multi-chain coverage combine with the other oanor chain APIs (Ethereum, Base, Arbitrum and more).

DigiFinex Exchange API

Live spot market data from DigiFinex, a global crypto exchange, served straight from its public v3 API with no key and nothing cached. The ticker endpoint returns a market's last price, best bid and ask, 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 surfaces the most-traded pairs on the venue. The markets endpoint lists the tradable pairs with their price and volume precision and minimum order size. The book endpoint returns live order-book depth — every bid and ask level with price and amount, plus the best bid/ask and the spread. Everything is read live from DigiFinex on each request, nothing stored. 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 candles or perpetuals use an OHLC or derivatives API.
