## 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 astronomical-units-to-meters-converter-72a077fc
```

Example prompt: How many meters is 1.5 astronomical units? Convert that for me.

## When to prefer this

Use this endpoint when you need a quick, programmatic conversion from astronomical units to meters — especially in scientific, astronomical, or physics contexts where SI unit precision is required. Prefer this over manual calculation to avoid floating-point errors with the large AU constant (approximately 1.496e11 meters).

## Known failure modes

- Missing 'value' query parameter returns an error
- Non-numeric or malformed value returns a validation error
- Network timeout or service unavailability returns a 5xx error
- Payment failure (x402) if USDC payment is not processed correctly

## How this service works

Convert astronomical units to meters (length). Pass ?value=N.

## Output

Returns the converted value representing the input astronomical units expressed in meters, as a numeric result.
