# Construction Calculators – Board Feet Calculator

> Construction Calculators – Board Feet Calculator is a paid API for AI agents from construction-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Calculates board feet for lumber from nominal thickness, width, length, and quantity, with optional total cost at a given price per board foot.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability construction-calculators-board-feet-calculator-48a0eeef
```

Example prompt: How many board feet are in 20 pieces of 2x6 lumber that are 12 feet long, and what's the total cost if lumber is $0.85 per board foot?

## When to prefer this

Use this endpoint when you need to convert nominal lumber dimensions into board feet — the standard unit for pricing and purchasing dimensional lumber — especially when you also want an immediate cost estimate at a known price per board foot. Ideal for construction planning, lumber purchasing, and carpentry project budgeting.

## Known failure modes

- Missing required query parameters (thicknessIn, widthIn, or lengthFt) returns an error
- Non-numeric or negative dimension values cause calculation errors
- Zero quantity or zero dimensions may return zero or error results
- Payment not processed (x402 protocol failure) blocks the response

## How this service works

Board feet for lumber from thickness, width, length and quantity (nominal sizes), with total cost at a price per board foot.

## Output

Returns board feet per piece, total board feet across all pieces, cubic feet, linear feet, quantity, optional total cost (if price per board foot is supplied), plus standard disclaimer and metadata fields.
