## 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 mac-address-colon-separated-format-validator-7c08fc23 -d '<json body>'
```

Example prompt: Can you check whether the string '2C:54:91:88:C9:E3' is a valid colon-separated MAC address?

## When to prefer this

Use this endpoint when you need a definitive, reliable check that a string is a colon-separated MAC address and a free sandbox alternative (POST /v1/sandbox/check-mac-colon) is unavailable or rate-limited. Prefer the free sandbox endpoint first; fall back to this paid endpoint when the sandbox is inaccessible or you need guaranteed SLA.

## Known failure modes

- Empty or missing 'value' field returns validation error
- String exceeding 20000 characters rejected
- Malformed input schema causes 400 error
- Network timeout or service unavailability returns 5xx
- Payment of exactly $0.001 USDC required; insufficient payment returns 402

## How this service works

Call when an agent needs whether a string is a colon-separated MAC address. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/check-mac-colon first.

## Output

Returns a boolean or structured result indicating whether the provided string conforms to the standard colon-separated MAC address format (six groups of two hexadecimal digits separated by colons, e.g. XX:XX:XX:XX:XX:XX).
