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 25 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/lighter: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
