## 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 agentshelf-hsl-to-hex-color-converter-55a5192a -d '<json body>'
```

Example prompt: Convert hsl(210, 75%, 45%) to its hex color code for me.

## When to prefer this

Use this endpoint when you need a deterministic, no-network color conversion from HSL to hex and have already exhausted the free sandbox option at /v1/sandbox/color-hsl-to-hex. It is best for agents that need exact hex codes from HSL inputs without relying on external services or libraries. Cost is $0.006 USDC per call, so prefer it only when the free path is unavailable.

## Known failure modes

- Invalid or malformed HSL text input returns an error
- Empty text field is rejected due to minLength:1 constraint
- HSL values outside valid ranges (hue >360, saturation/lightness >100%) may produce unexpected results or errors
- Network unavailability returns a 402 or connection error; prefer free sandbox endpoint /v1/sandbox/color-hsl-to-hex when available

## How this service works

Call when an agent needs a color converted with hsl-to-hex. No network. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/color-hsl-to-hex first.

## Output

Returns the hex color code (e.g. #3399CC) corresponding to the provided HSL input, as a text string.
