#curve

Live protocol metrics for Convex Finance, the yield-booster built on top of Curve (it lets liquidity providers and CRV holders earn boosted rewards), keyless. Get the total value locked, the boosted Curve yield pools with their TVL and APY (base + rewards), per-chain TVL, and protocol fees and revenue. One combined overview endpoint snapshots it all. Live, nothing stored. The yield-aggregator metrics layer for DeFi dashboards, yield, farming and analytics apps — distinct from DEX, lending, restaking and generic DeFi/TVL browsers, this is Convex Curve-boosted yield specifically.

Live DeFi data from Curve Finance — the dominant decentralised exchange for stablecoins and pegged assets (StableSwap AMM) — served from its public API as clean JSON, no cache. List every chain Curve runs on and the pool registries on each; pull the liquidity pools on a chain/registry with each pool's USD TVL, underlying coins and prices, amplification coefficient, virtual price and CRV gauge APY (sorted by TVL); fetch one pool's full detail by address; or read a chain's total and per-pool trading volume. Read live from Curve, nothing cached. This is Curve's own StableSwap pool, TVL and gauge layer across Ethereum and 20+ L2s — distinct from on-chain explorers, general DEX-pool feeds and price APIs: protocol-level data for the largest stablecoin AMM in DeFi.

Horizontal road-curve geometry as an API, computed locally and deterministically — the curve-element, stationing and design-radius numbers a highway engineer, surveyor or civil-design tool lays out a road or railway curve with. The geometry endpoint takes the radius and the intersection (deflection) angle and returns the full simple circular curve: the tangent T = R·tan(Δ/2), the curve length L = R·Δ in radians, the long chord LC = 2R·sin(Δ/2), the middle ordinate M = R(1−cos(Δ/2)) and the external distance E = R(sec(Δ/2)−1), plus the degree of curve (arc definition) = 5729.578 ÷ R, the US shorthand for sharpness. The stations endpoint lays the curve out from the PI: the PC (point of curvature) = PI − tangent and the PT (point of tangency) = PC + curve length — and it reminds you the PT is reached along the arc, not by adding the tangent again. The min-radius endpoint gives the minimum radius for a design speed (AASHTO) R = V² ÷ (15·(e + f)), where e is the superelevation and f the side-friction factor, the banking-plus-grip that holds a vehicle in the turn. Everything is computed locally and deterministically, so it is instant and private. Ideal for highway- and rail-design tools, surveying and civil-engineering utilities, and CAD/GIS road layout. Pure local computation — no key, no third-party service, instant. US units (ft, mph). 3 compute endpoints. For slope and grade use a slope API; for open-channel drainage a Manning API.

Bézier-curve geometry maths as an API, computed locally and deterministically. The point endpoint evaluates a quadratic (three control points) or cubic (four) Bézier curve at a parameter t between 0 and 1 using de Casteljau's algorithm, returning the point on the curve and the tangent there — its direction vector, angle and speed (the derivative B'(t)). The length endpoint computes the arc length of the curve by fine polyline sampling, together with the straight-line chord length and the axis-aligned bounding box (min and max x and y, width and height). The split endpoint splits the curve at a parameter into two sub-curves and returns the control points of each — the standard de Casteljau subdivision used for trimming and adaptive rendering. Control points are passed as plain x/y coordinates. Everything is computed locally and deterministically, so it is instant and private. Ideal for graphics, CAD, font, animation, game-engine and vector-design app developers, path and curve tools, and computational-geometry education. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is Bézier-curve geometry; for animation easing and timing functions use an easing API.
