All projects on Base matching “calculator api”

Calculate gross/net rental yield, income, operating costs and simple payback in OMR. Calculations only. Paid per call via x402; no API key required.

Evaluate a mathematical expression with optional named variables — arithmetic, comparison and logic operators plus functions like sqrt, abs, min, max, sin, cos, log, floor, round, etc. A syntax error, an undefined variable, or a non-finite result is a clean 400. The factorial operator is disabled for safety.
