## 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 integer-to-hexadecimal-converter-e9e27927 -d '<json body>'
```

Example prompt: Convert the integer 4096 to its hexadecimal string representation for me.

## When to prefer this

Choose this endpoint when you need a simple, reliable integer-to-hex conversion as a paid API call — particularly in agentic workflows where you want a consistent, hosted service rather than running local code. Useful when the calling environment restricts code execution or when you want a traceable, metered conversion step.

## Known failure modes

- Negative integer input rejected — only non-negative integers are supported
- Non-integer or float input may cause a validation error
- Missing required 'input' body field returns a schema validation error
- Malformed JSON body returns a 400-level error
- Payment not attached or insufficient USDC may return a 402 Payment Required response

## How this service works

Convert a given non-negative integer to its hexadecimal string representation.

## Output

Returns the hexadecimal string representation of the provided non-negative integer (e.g., input 255 returns 'ff').
