Break-even and cost-volume-profit maths as an API, computed locally and deterministically. The breakeven endpoint computes the break-even point of a product — the units you must sell to cover all costs, fixed costs ÷ (price − variable cost) — together with the break-even revenue, the contribution margin per unit and the contribution-margin ratio. The target endpoint computes the units and revenue needed to reach a target profit, (fixed costs + target profit) ÷ contribution margin. The margin-of-safety endpoint takes an actual sales level (in units or revenue) and returns the margin of safety — how far sales can fall before a loss — both in units and as a percentage, plus the profit at that level. Everything is computed locally and deterministically, so it is instant and private. Ideal for business, startup and finance app developers, pricing and product-planning tools, and small-business and accounting dashboards. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is cost-volume-profit analysis; for per-unit margin and markup pricing use a margin API.

The North American Industry Classification System (NAICS 2022) as an API — 2,100+ industry codes in a 5-level hierarchy (sector → subsector → industry group → industry → national industry). Look up any code (e.g. 541511 → Custom Computer Programming Services) with its full ancestor chain and direct children; search industries by title (e.g. "software", "restaurant"); or navigate the tree from the 20 top-level sectors down. NAICS is the standard used by US, Canadian and Mexican statistical agencies to classify business establishments. Ideal for business classification, market research, CRM enrichment, lead segmentation and economic analysis.
