healthy 4,214 Subscribers

Live market data for Lighter, the zkSync-based order-book perpetuals and spot DEX, with no key. List every market (perps and spot) with its id and status; pull exchange-wide stats with last price, 24h volume and daily change for every market; read the live order book; and stream recent public trades. Symbols are accepted by name (BTC, ETH, AAPL) or numeric market id and resolved automatically. Lighter notably lists tokenised-equity perps (AAPL, TSLA …) alongside crypto — ideal for cross-asset derivatives dashboards and market monitors.

Sophon Chain API

Real-time on-chain data for Sophon (chain-id 50104), a ZK Layer-2 built on the zkSync Elastic Chain stack and focused on consumer and entertainment apps, where gas is paid in the native SOPH token. The status endpoint returns the chain id, network id, latest block height, native symbol and node client version so you can confirm the chain is live and synced. The block endpoint returns a block by decimal or 0x-hex height — or the latest block when no height is given — with its hash, parent hash, timestamp (raw and ISO), transaction count, gas used and limit, base fee and miner. The gas endpoint returns the current gas price in both wei and gwei at the latest block. The balance endpoint returns the native SOPH balance (in wei and human-readable units) and the transaction count (nonce) for any 0x address. The meta endpoint documents the chain id, decimals and ecosystem. Reads a live Sophon JSON-RPC node directly, so values are current to the latest block. Live, nothing stored. 5 endpoints. This serves native-coin and chain data; for ERC-20 token balances or contract calls use a dedicated token/contract API.

Abstract Network API

Live on-chain data for Abstract (chain-id 2741), a consumer-focused ZK Stack Layer 2 (zkSync-based) that settles to Ethereum and uses ETH for gas. Read the chain status — chain id, latest block number, current gas price, node client version and sync state — fetch any block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and limit, base fee and proposer, read the current gas price and max priority fee in both wei and gwei, and look up any account address for its ETH balance (in wei and whole ETH) and transaction nonce. Addresses use the standard 0x EVM hex form. A short protective cache keeps responses fast while staying within a few seconds of the chain. Distinct from other Layer-1, Layer-2 and Cosmos-chain APIs on the marketplace: this surfaces the Abstract ZK network specifically.

zkSync Era On-Chain API

Live zkSync Era on-chain data as an API, built on the open Blockscout explorer. zkSync Era (chain id 324) is a leading Ethereum zk-rollup Layer-2 by Matter Labs; its native currency is ETH and fees are a fraction of mainnet. Pull network stats (total blocks and transactions, ETH price, live gas), a gas oracle with slow, average and fast prices in gwei, the most recent blocks and full block detail by height or hash. Look up any address for its balance and contract status, any transaction by hash for its value, fee, status, sender and receiver, and any ERC-20 token by contract for its name, symbol, decimals, holders and USD rate. A universal search resolves addresses, tokens, blocks and transactions in one call. Real on-chain data, no key needed upstream. Ideal for zkSync wallets, block explorers, gas trackers, DeFi dashboards and on-chain analytics.

Crypto Derivatives API

A cross-exchange aggregator of cryptocurrency perpetual-futures and derivatives markets — the funding rates, open interest and volume that drive leveraged crypto trading, pulled together across every listed derivatives exchange (Binance, Bybit, OKX, Hyperliquid, MEXC and dozens more). The perps endpoint ranks the largest perpetual markets by open interest with their price, funding rate, open interest and 24h volume. The funding endpoint compares the funding rate of one asset (e.g. BTC, ETH, SOL) across every exchange that lists it, with the average — so you can spot funding dislocations and basis trades at a glance. The exchanges endpoint ranks derivatives venues by open interest with their perpetual and futures pair counts. The overview endpoint aggregates total open interest, total 24h volume and the perpetual-pair count across the whole derivatives market. The meta endpoint documents the API. Live aggregated data, lightly cached; funding rates are percentages, open interest in USD per market and BTC for venue totals. Live. 5 endpoints. This aggregates derivatives across all exchanges; for a single exchange's raw order book use that exchange's API.
