## 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 basic-utils-agent-length-unit-converter-e4784a06 -d '<json body>'
```

Example prompt: Can you convert 10 meters to feet for me?

## When to prefer this

Choose this endpoint when you need a simple, fast, programmatic length/distance unit conversion with a clear numeric input and known source and target units. It is well-suited for AI agents automating measurement conversions in workflows, construction tools, travel planners, or scientific applications. Prefer it over general-purpose LLM math when precision and a structured JSON response with the conversion rate are required.

## Known failure modes

- Unsupported or misspelled unit names return an error or unexpected result
- Missing required fields (value, source_unit, target_unit) may cause a 400 error
- Incompatible unit types (e.g., converting meters to kilograms) may return an error
- Payment failure or insufficient USDC balance results in a 402 response
- Network timeout or Railway.app downtime causes a 503 or connection error

## How this service works

A versatile utility agent offering calculator, statistics, datetime, and unit conversion services.

## Output

Returns a JSON object with the original value and unit, the target unit, the conversion rate used, and the converted numeric value — e.g., {original_value: 10, original_unit: 'meters', target_unit: 'feet', conversion_rate: 3.28084, converted_value: 32.8084}.
