## 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 cable-mass-calculator-4faa5199 -d '<json body>'
```

Example prompt: Can you calculate the mass of a copper cable that is 150 meters long with a cross-sectional area of 16 mm²?

## When to prefer this

Choose this endpoint when you need a quick programmatic calculation of cable mass from physical parameters such as length, cross-sectional area, and material density, especially within automated engineering workflows or materials procurement pipelines.

## Known failure modes

- Missing required parameters such as length or cross-section returns a 400 error
- Invalid or unsupported material type returns an error
- Negative or zero length/area values may return a validation error
- Service unavailable returns a 5xx error

## How this service works

Conductor mass is calculated from nominal cross-section, core count and length against the material density; for a nominal cross-section this is exact and independent of stranding. Total cable mass and the copper share are returned as a range derived from published manufacturer weight tables per cross-section band, not as a type-test value. Insulation, filler and armour are not modelled individually.

## Output

Returns the computed mass of the specified cable, typically expressed in kilograms, based on the provided length, cross-sectional area, and material density inputs.
