We're building the most comprehensive crypto data API we can, and it's still growing — there's always a coin, a field or an endpoint we haven't got to yet.
Please tell us about any data you think Crypto Data API should nail but doesn't. We're data nerds who love to geek out about market data, trading bots, AI agents, or how to make your trading stack work in general. Prefer a form? Send feedback.

Join us on DiscordA zk-rollup order-book perps DEX built for verifiable, low-latency trading.
Lighter is a decentralized perpetual-futures exchange built on a zero-knowledge rollup, pairing a central limit order book with verifiable on-chain settlement and a focus on low-latency, MEV-resistant execution. It is one of the newer entrants in the on-chain perps space; it isn't in our BTC-only cross-exchange feeds, but we pull its total open interest, 24h volume and BTC funding rate directly from its own public API.
Live crypto market data covering Lighter and the other major venues — every metric one API call away.
Cross-exchange open interest, funding and liquidations — all programmatic. Start free: 1,000 requests/day, no card.
