Funding

Current perpetual funding, normalized to an eight-hour rate and annualized, with history and a one-year percentile baseline. Positive means longs pay shorts; it is a cost of holding, not a direction forecast.

What it does

Current perpetual funding rate for one coin (hourly rate plus an annualized estimate), merged across providers, with its 24h and 7d trajectory AND the underlying 8h-bucket series. Positive means longs pay shorts. The trajectory is the point: the same +6% annualized reads as post-flush relief if it fell from +40% and as shorts capitulating if it rose from -20%. The series carries the shape a trailing delta flattens away — a steady drift and a spike that retraced give the same 24h change off opposite tapes — plus the window's own low/high, so the current rate can be judged against where it has actually been rather than an absolute threshold. A 1y line ranks the current rate against a year of daily closes (percentile, low/median/high with dates), so 'high' means high for this coin, not just for the week. Set 'points' to trim the series (omit for the full ~10-day window; 0 to suppress it).

Parameters

NameTypeDescription
symbolrequiredpathstringCoin symbol, e.g. "BTC".
pointsqueryintegerHow many of the newest 8h buckets to emit. Omit for the full window (30 points ~ 10 days); 0 suppresses the series and returns the summary only.

Call it

One API key works for MCP, REST and WebSocket; each call uses one unit. Agents without an account can pay per call with x402.

Sample response

A real response captured 2026-11-13. Interactive is the tool's MCP App rendering it, as Claude, ChatGPT and other MCP Apps hosts show it; here it is read-only. JSON is what REST and WebSocket return, and the structuredContent of an MCP call (trimmed for length), with generatedAt for freshness. Text is the report an MCP client hands to a model.
