CoinBoss is the right starting point for derivatives traders who need a single dashboard covering liquidations, open interest, funding rates, and ETF flows without paying anything today. Its API is currently free and unauthenticated, which is genuinely useful, but the paid tier structure is unfinished and launch-date-free, making it a risky dependency for any production build. If you need a proven, commercially licensed data feed right now, CoinGlass has a longer track record and live paid plans.
What is CoinBoss?
CoinBoss aggregates real-time crypto derivatives and on-chain data: liquidations across major exchanges, open interest, funding rates, long-short ratios, spot and derivatives volume, ETF flows, stablecoin issuance and exchange balances.
How we scored CoinBoss
Capability scores well because the breadth of derivatives data is genuine: 26 exchanges, 4,681 perpetual symbols, 9 distinct feature sections including options analytics and Hyperliquid-specific tools that most free competitors omit. Ease of use benefits from zero-friction access, no account required, and a clearly organized navigation structure, though the web-only delivery and absence of alerts cap the score. Value is strong for the current free tier but the planned paid pricing ($199/month for a commercial license with no confirmed launch date) makes the long-term value proposition hard to assess. Delivery scores low because the entire commercial API structure is unfinished and contractually unenforceable: a production team building on this today has no SLA, no rate-limit guarantee, and no confirmed timeline, which is a real delivery risk that the marketing framing of the pricing page does not adequately flag.
Pros and cons
What we liked
- All 143 API endpoints are currently free and require no authentication, making it the lowest-friction derivatives data source available for developers and researchers right now.
- Liquidation data is organized into multiple linked views: a live feed, coin ranking by notional, largest single orders, and per-exchange breakdowns, giving traders more resolution than a single aggregate number.
- Coverage spans 26 exchanges, 4,681 perpetual symbols, and 1,090 active coins, plus dedicated Hyperliquid tools, ETF flow data, and options analytics that most competing free dashboards omit.
Where it falls short
- The paid API tiers have no confirmed launch date and the pricing structure is explicitly subject to change before release, meaning any production dependency on this API is built on an informal arrangement with no SLA or contract.
- The platform is web-only with no mobile app, which is a real gap for traders who monitor liquidation events on the move and need push alerts or a native mobile experience.
- There is no alert or notification system visible on the platform: a trader cannot set a liquidation threshold or funding rate trigger and receive a notification, which is a standard feature on competing derivatives dashboards.

Who should use CoinBoss?
Derivatives traders who watch leverage buildup and liquidation cascades will get the most out of CoinBoss. The liquidation feed, exchange breakdown, and heatmap views are built for exactly that workflow: spotting where forced orders are concentrating, which venues are driving a flush, and how large the notional is relative to recent history. Quant researchers and data engineers who want free API access to 143 endpoints covering OI, funding, and liquidation data will also find it immediately useful, since the current no-auth setup removes all onboarding friction.
Spot traders, long-term investors, and anyone who needs portfolio tracking, tax reporting, or trade execution tools should look elsewhere. CoinBoss has no portfolio features and is not a trading venue. If you need a commercially licensed derivatives data feed with a live SLA today, AlphaVue is worth evaluating for its structured, evidence-backed research layer, though it targets equity research more than raw crypto derivatives feeds.
