**APIs profiled:** 1

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.
