#contango

The shape of the commodity futures curve — contango versus backwardation — and the roll yield it pays, computed live from Yahoo Finance dated futures contracts, no key, nothing stored. A single commodity price hides the most important thing about it: what the market charges to hold it forward. When deferred contracts cost MORE than the front (an upward curve, contango) a long futures position bleeds money as it rolls up the curve each month; when they cost LESS (a downward curve, backwardation — classic for crude oil in tight markets) the roll pays you. That roll yield, not the spot move, is what drives the long-run return of commodity-index investing. This API reads the actual dated contracts — the front month and the deferred months out the curve — for crude oil, natural gas, gasoline, gold, silver, copper, corn, wheat and soybeans, and returns the full term structure, the front-to-second-month roll yield annualised, the curve shape and the front-vs-back spread. The curve endpoint returns one commodity's full chain; the screener endpoint ranks every commodity by roll yield, separating the backwardated markets (positive carry for a long) from the contango ones (negative carry). This is the commodity futures term-structure / roll-yield cut — distinct from the crypto dated-futures curve API, the inter-commodity crack/crush spread API, the commodity-momentum and seasonality APIs and the spot price feeds. It is the carry, read straight off the curve.

Die Form der Aktienvolatilitätskurve – das am meisten beachtete Regime-Signal in der Optionswelt – live von Yahoo Finance berechnet, kein API-Key, nichts gespeichert. Ein VIX-Wert sagt Ihnen, wie verängstigt der Markt gerade ist; die Term Structure sagt Ihnen, ob diese Angst kurzfristige Panik oder ein ruhiger, anhaltender Zustand ist und in welche Richtung sie sich bewegt. Diese API liest die implizite Volatilitätskurve des S&P 500 über vier Laufzeiten – den 9-Tage-VIX, den 30-Tage-VIX, den 3-Monats-VIX und den 6-Monats-VIX – und wandelt sie in ein Regime um. Wenn die Kurve ansteigt (VIX < VIX3M < VIX6M), befindet sich der Markt im Contango: ruhig, mit kurzfristiger Volatilität günstiger als langfristige, der Zustand, den Short-Vol-Strategien ernten. Wenn sie in Backwardation invertiert (VIX über VIX3M), ist die kurze Seite teurer als die lange: akuter Stress, Angst steigt, historisch nahe an Kapitulation. Der Structure-Endpoint gibt die Live-Kurve, das Contango-Verhältnis (VIX / VIX3M), das Short-End-Verhältnis (VIX9D / VIX), den Roll-Yield, den eine Short-Vol-Position erzielen würde, die Steigungsklassifikation und eine Regime-Lesart zurück, mit VVIX (der Volatilität des VIX) als Kontext. Der History-Endpoint gibt die tägliche Zeitreihe des Contango-Verhältnisses zurück und markiert jeden Backwardation-Tag. Der Percentile-Endpoint ordnet das heutige Contango-Verhältnis in seine Ein-Jahres-Spanne ein. Dies ist der Volatilitäts-Term-Structure / Contango-Backwardation-Schnitt – unterschieden vom Cross-Asset-VIX-Family-Level-Board, dem Crypto-DVOL-Index und den Realisierte-Volatilität-APIs. Es ist die Form der Angst, nicht ihr Niveau.

The shape of the crypto dated-futures curve and the annualised basis at every expiry, read live from Deribit's public futures book — no key, nothing stored. A single spot price tells you nothing about what the market pays to hold a position over time: dated futures trade at a premium (contango) or a discount (backwardation) to spot, and that premium, annualised, is the cash-and-carry yield basis traders harvest. The curve endpoint returns, for a currency (BTC or ETH), the spot index, the perpetual and every listed dated future — each with its days to expiry, mark price, the absolute and percent basis to spot and the annualised basis — plus the overall curve shape (contango or backwardation) and the front- and back-month annualised basis. The basis endpoint returns the annualised basis (cash-and-carry yield) for a chosen expiry, or the front future. This is the futures-curve / term-structure cut for crypto — distinct from the spot-versus-perpetual basis API (a single point on the curve), and from the funding-rate, options, max-pain, gamma and price APIs in the catalogue. Currency is BTC or ETH; expiry is a Deribit code like 26JUN26.

Live crypto spot-versus-perpetual basis and premium as an API, served from the Bybit v5 feed. The basis is the gap between a coin's perpetual-futures price and its spot price: when the perp trades above spot the market is in contango (leveraged longs are paying up), when below it is in backwardation. For any coin this returns the spot price, the perp last, mark and index price, the basis in absolute and percentage terms, the mark-to-index premium, the market structure, and the funding rate — per-8-hour and annualised — that arbitrages the basis away. Get a coin's basis, or scan the majors ranked by basis. The cash-and-carry and funding-arbitrage signal layer for trading and dashboard apps. Live, no key, no cache. Distinct from funding-rate, open-interest and price APIs — this is the spot-perp basis.
