Options pricing and greeks calculator, deterministic. Answers "what are the greeks for this option", "what is the implied vol of this price". Buyer supplies spot or forward, strike, expiry (ISO date or years), and iv or price; returns Black-Scholes or Black-76 price, delta, gamma, vega, theta, rho, intrinsic/time value, breakeven — or the implied vol solved from price. Pure math (normal CDF accurate to 1e-15), no data source, no LLM, no key.

price-ascending: candidates are ordered by the listed price of the operation, with no managed-first preference applied. Unlike /v1/apis, this surface does not rank Apiosk-settled listings above federated ones — a comparison that reorders on commercial grounds is not a comparison. Pass sort=managed_first for the catalog's ordering.

Compared: listed price, settlement rail and input compatibility. Not measured yet: latency, reliability, result quality, and provider terms such as rate limits, jurisdiction and licensing.
