## 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 feet-to-astronomical-units-converter-f7f6e021
```

Example prompt: How many astronomical units is 1,000,000 feet? Just convert that length value for me.

## When to prefer this

Use this endpoint when you need to convert a specific distance expressed in feet into astronomical units, especially in scientific, aerospace, or astronomy contexts where AU is the standard unit. Prefer this over general-purpose math tools when you want a direct, paid microservice call with no additional computation required.

## Known failure modes

- Missing 'value' query parameter returns an error
- Non-numeric value string causes a parsing or validation error
- Extremely large or small numbers may cause precision issues
- Payment not sent or insufficient USDC balance results in 402 Payment Required

## How this service works

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

## Output

Returns the input value in feet converted to its equivalent in astronomical units (AU), a standard unit of distance used in astronomy equal to the average Earth-Sun distance.
