## 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-pounds-to-grams-converter-32443277
```

Example prompt: How many grams are in 2.5 pounds?

## When to prefer this

Use this endpoint when an agent needs a precise, programmatic pounds-to-grams mass conversion without implementing conversion logic locally. Ideal for workflows that handle user-provided imperial mass values and need metric equivalents, especially within x402-payment-compatible pipelines.

## Known failure modes

- Missing ?value parameter returns an error or bad request
- Non-numeric value passed to ?value causes a parse error
- Negative or zero values may return unexpected results depending on validation
- Payment not processed results in 402 response blocking conversion

## How this service works

Convert pounds to grams (mass). Pass ?value=N.

## Output

A numeric value representing the input pounds converted to grams (e.g., 2.5 lbs → 1133.98 g), returned as a structured response from the API.
