## 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 awg-metric-calculator-042b68e6 -d '<json body>'
```

Example prompt: Can you convert 12 AWG wire to its metric equivalent — I need the diameter in millimeters and the cross-sectional area in mm²?

## When to prefer this

Use this endpoint when you need a quick, reliable AWG-to-metric conversion for wire diameter, cross-sectional area, or resistance, especially in workflows involving international sourcing, IEC compliance, or engineering calculations where metric units are required. Prefer this over manual lookup tables or general-purpose unit converters that may not cover wire gauge specifics.

## Known failure modes

- Invalid or out-of-range AWG number (AWG values typically range from 0000 to 40)
- Malformed request body returns an error
- Non-integer or non-numeric AWG input may cause a parsing error
- Extremely unusual gauges outside standard tables may not be supported

## How this service works

Uses the geometric AWG definition, so results are exact for solid round conductors. Mass per metre and resistance follow from the material density and resistivity at 20 degrees Celsius; stranded conductors carry roughly two to five percent more mass and resistance per metre than the same nominal size and are not modelled separately. Supply either awg or cross_section_mm2, not both. Sizes 4/0 through 40 AWG are covered.

## Output

Returns the metric equivalent properties for the given AWG wire size, including diameter in millimeters, cross-sectional area in mm², and potentially resistance per unit length — enabling direct use in metric-standard engineering contexts.
