Every result is deterministic: the same inputs always give the same numbers. The calculators are also exposed as an MCP server and a REST API, and each MCP result is cryptographically signed (ECDSA P-256), so an AI agent or a trading bot can check that the numbers came from the formulas and were not altered. The core calculators are checked against public test vectors on a live page (/verify).
It is free, needs no signup, and returns exact numbers from published formulas instead of estimates. The same tools work in the browser, over REST and over MCP, so a trader and an AI agent get identical answers. It covers options, forex, risk statistics and crypto perpetual futures in one place, including coin-margined contracts.
Developers building AI agents and trading bots who need verifiable numbers from a tool call, and traders who want fast, exact calculations for options, forex and crypto futures without creating an account.
