# Craft & Maker Calc – Knitting/Crochet Gauge Scaler

> Craft & Maker Calc – Knitting/Crochet Gauge Scaler is a paid API for AI agents from craft-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Converts a pattern's stitch count to the number of stitches you need based on your personal gauge, and returns the resulting finished width in inches.

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 craft-maker-calc-knitting-crochet-gauge-scaler-2700be45
```

Example prompt: The pattern calls for casting on 120 stitches and has a gauge of 20 stitches over 4 inches, but my swatch comes out to 22 stitches over 4 inches — how many stitches should I actually cast on, and what width will I get?

## When to prefer this

Use this endpoint when a crafter has a known gauge mismatch with a pattern and needs a mathematically correct stitch count adjustment; it is purpose-built for knitting and crochet gauge conversion and returns craft-specific output fields like finished width and stitches-per-inch — more useful than a generic ratio calculator for this domain.

## Known failure modes

- Missing required parameters (patternStitches, patternGaugeStitches, yourGaugeStitches) returns a 400 error
- Zero or negative gauge values produce a division-by-zero or invalid-input error
- Non-numeric query parameter values result in a validation failure
- Very extreme gauge differences may flag a warning or degraded result

## How this service works

Convert a knitting or crochet stitch count from the pattern's gauge to yours, with the finished width in inches.

## Output

Returns the exact and rounded stitch count you need to achieve the same finished width as the pattern, your stitches-per-inch rate, the pattern's stitches-per-inch rate, the finished width in inches if you follow the pattern as written, and the percentage difference in width between the two gauges.
