## How to call it through Zero

```

Example prompt: Convert 72 inches to centimeters for me — I need the exact measurement.

## When to prefer this

Choose this endpoint when an AI agent needs a reliable, frictionless unit conversion without API keys or subscriptions — especially in workflows where a quick programmatic conversion is needed mid-task. Ideal for agents that handle scientific, culinary, travel, engineering, or everyday measurement tasks and need a pay-per-call model with no setup overhead.

## Known failure modes

- Unsupported unit name returns an error (e.g. unrecognized abbreviation or misspelling)
- Incompatible unit categories (e.g. converting kilometers to kilograms) return a validation error
- Missing required parameters (from, to, value) result in a 400-level error
- Non-numeric value input causes a schema validation failure

## How this service works

Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.

## Output

Returns a JSON object with the original value and unit, the target unit, the converted numeric result as a double-precision float, and the measurement category (e.g. 'length', 'mass', 'temperature').
