## 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 jewelry-maker-calc-bracelet-anklet-length-calculator-8161660e
```

Example prompt: My customer has a 6.75-inch wrist — what finished bracelet length do I need for a comfortable fit, assuming a standard 0.5-inch clasp?

## When to prefer this

Use this endpoint when you need a precise, formula-based finished bracelet or anklet length from a measured wrist or ankle circumference, especially when you need clasp allowance factored in and want to compare multiple fit styles at once. Prefer it over manual lookup charts when building a jewelry-making tool, e-commerce sizing guide, or custom order workflow.

## Known failure modes

- Missing circumferenceInches parameter returns a validation error
- Circumference value of 0 or negative may produce nonsensical results
- Clasp value outside 0–2 inch range may be rejected or clamped
- Unrecognized fit string value falls back to standard fit or returns an error
- Network or payment (x402) failure returns no result

## How this service works

Bracelet or anklet length from wrist or ankle circumference and fit (snug, standard, comfortable, loose), with clasp allowance.

## Output

Returns the recommended finished bracelet/anklet length in both inches and centimeters for the chosen fit, along with the ease added, the body (chain/bead strand) length, and a breakdown of all four fit options (snug, standard, comfortable, loose) for the given circumference.
