## 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 gradians-to-arcseconds-angle-converter-52869d82
```

Example prompt: Can you convert 200 gradians to arcseconds for me?

## When to prefer this

Use this endpoint when you need a quick, reliable server-side conversion from gradians to arcseconds without implementing the math locally. Ideal for surveying, geodesy, or astronomy applications that use gradian inputs but require arcsecond outputs. Prefer this over manual calculation when precision and consistency are important.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Non-numeric value passed as input causes a parse or validation error
- Very large or very small floating point values may lose precision
- Payment failure (x402) if USDC funds are insufficient or wallet not configured

## How this service works

Convert gradians to arcseconds (angle). Pass ?value=N.

## Output

Returns the numeric equivalent of the input gradian value expressed in arcseconds (where 1 gradian = 3240 arcseconds, so 400 gradians = 1,296,000 arcseconds).
