## 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-stitch-count-for-area-19ce0ac7
```

Example prompt: I'm knitting a scarf that should be 6 inches wide and 60 inches long — my gauge is 5 stitches per inch and 7 rows per inch. How many stitches do I need to cast on and how many rows will I knit?

## When to prefer this

Use this endpoint when you need to determine how many stitches to cast on and how many rows to work for a knitting or crochet project given a target finished size and your personal gauge. Ideal for pattern-agnostic stitch planning where you know your gauge and your desired dimensions. Prefer over manual calculation or generic calculators when you also need the repeat-multiple rounding feature for stitch patterns.

## Known failure modes

- Missing required query parameters (widthInches, heightInches, stitchesPerInch, rowsPerInch) returns an error
- Non-numeric or zero/negative values for gauge or dimensions may return an error or nonsensical result
- Payment failure (x402 flow) if USDC balance is insufficient or wallet not configured
- Extremely large dimensions or very small gauge values may produce very large stitch counts but should still compute correctly

## How this service works

Stitches and rows needed to cover a width and height at your stitch and row gauge, with total stitches.

## Output

Returns stitches (rounded), rows (rounded), exact stitch count, exact row count, total stitches, actual width and height in inches after rounding, and optional rounding metadata. If a repeat multiple is provided, stitches are rounded up to the nearest multiple.
