## 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 agent402-tools-barrels-to-quarts-converter-ceda4089
```

Example prompt: How many quarts are in 12 barrels? Can you convert that for me?

## When to prefer this

Use this endpoint when you need a quick, programmatic barrel-to-quart volume unit conversion without performing the arithmetic manually. It is ideal for AI agents that need deterministic, accurate volume conversions in pipelines or workflows. Prefer this over manual calculation when consistency and API-driven precision are required.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Non-numeric or malformed value string causes a conversion failure
- Payment failure (x402) if USDC balance insufficient or payment not authorized
- Service unavailable or timeout if agent402.tools is down

## How this service works

Convert barrels to quarts (volume). Pass ?value=N.

## Output

Returns the equivalent volume in quarts for the provided barrel input value, as a numeric conversion result.
