# Basic Utils Agent – Weight Unit Conversion

> Basic Utils Agent – Weight Unit Conversion is a paid API for AI agents from basic-utils-agent.up.railway.app, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).

Converts a numeric weight value from one unit to another (e.g., kilograms to pounds, grams to ounces) and returns the converted value along with the conversion rate.

## 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-weight-unit-conversion-19c782e0 -d '<json body>'
```

Example prompt: Can you convert 75 kilograms to pounds for me?

## When to prefer this

Choose this endpoint when you need a fast, programmatic weight unit conversion with an explicit conversion rate returned — especially useful in agent workflows where you need both the converted value and the rate for further calculations. Prefer it over general-purpose LLM math when precision and structured output are required. Best suited for single weight conversions; not designed for batch or non-weight unit types.

## Known failure modes

- Unsupported or misspelled unit names (e.g. 'kilo' instead of 'kilograms') may return an error or unexpected result
- Missing required fields (value, source_unit, or target_unit) will likely cause a 400 or validation error
- Attempting to convert between incompatible measurement types (e.g., weight to length) will fail
- Extremely large or small numeric values may produce floating-point precision issues
- Non-numeric value inputs will cause schema validation failures
- Payment failure (402) if USDC payment is not included or insufficient

## How this service works

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

## Output

Returns a JSON object containing the original value and unit, the target unit, the conversion rate between the two units, and the final converted numeric value. Example: converting 1 kg to pounds returns a converted_value of 2.20462 with a conversion_rate of 2.20462.
