Lighter

Lighter is a decentralized perpetual futures exchange built on zkLighter, a zero-knowledge rollup that produces verifiable proofs of order matching and liquidations while targeting the latency of a centralized venue. Traders register a Lighter account by signing with an Ethereum wallet, then operate it through up to 256 API keys across master and sub-accounts. The public zkLighter REST API exposes 78 operations covering order books, trades, candles, funding rates, accounts, positions, public pools, referrals, deposits, transfers and withdrawals, alongside a WebSocket stream carrying order book, trade, candle, position and account-transaction channels. Writes are signed transactions rather than plain authenticated calls: clients sign an order, cancel, modify or transfer body with an API private key and submit it via sendTx or sendTxBatch. Lighter ships first-party Python and Go SDKs, runs a full testnet deployment, publishes a 239-entry numeric error registry, weighted per-tier rate limits, and a vulnerability disclosure policy.

Lighter publishes 13 APIs on the APIs.io network, including account API, announcement API, block API, and 10 more. Tagged areas include Company, Trading, Cryptocurrency, Decentralized Finance, and Perpetual Futures.

The Lighter catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Lighter’s developer surface includes documentation, API reference, getting-started guide, signup flow, pricing, support, authentication, and 24 more developer resources.
