## 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 cisco-dotted-mac-address-validator-50c82ecd -d '<json body>'
```

Example prompt: Is the string '1a2b.3c4d.5e6f' a valid Cisco dotted MAC address?

## When to prefer this

Choose this endpoint when you specifically need to validate the Cisco dotted notation MAC address format (xxxx.xxxx.xxxx) rather than other MAC formats like colon-separated (xx:xx:xx:xx:xx:xx) or hyphen-separated. Prefer the free sandbox endpoint POST /v1/sandbox/check-mac-dot first; use this paid endpoint when the sandbox is unavailable or when production reliability is required.

## Known failure modes

- Empty or missing value field returns validation error
- String exceeding 20,000 characters rejected
- Malformed request body returns 400 error
- Non-dotted MAC formats (colon-separated, hyphen-separated) may return false even if valid in other notations
- Payment failure returns 402 Payment Required

## How this service works

Call when an agent needs whether a string is a Cisco dotted MAC address. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/check-mac-dot first.

## Output

A boolean or structured response indicating whether the submitted string conforms to the Cisco dotted MAC address format (three groups of four hexadecimal digits separated by dots, e.g. 1234.5678.9abc).
