## 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-syntexa-ch-mac-address-regex-extractor-97461707 -d '<json body>'
```

Example prompt: Can you extract all MAC addresses from this network scan output? Here's the text: 'Device at 00:1A:2B:3C:4D:5E connected to switch port 3, another at AA:BB:CC:DD:EE:FF on port 7.'

## When to prefer this

Use this endpoint when you need to reliably extract colon-formatted MAC addresses from arbitrary text without running a local regex. It is a pure computation endpoint with no network calls or LLM involvement, making it fast and deterministic. Prefer the free POST /v1/sandbox/regex-mac endpoint for testing or low-volume use before committing to paid calls. Avoid if you need dash-separated or Cisco dotted-quad MAC format support, or if you expect more than 20 MAC addresses in a single text.

## Known failure modes

- Empty match list returned when no MAC addresses exist in text — call is still billed $0.006
- Input text exceeds 100,000 character limit — request rejected
- Malformed input (missing or empty 'text' field) — request rejected
- Only colon-separated format matched; dash-separated (00-1A-2B-3C-4D-5E) or dotted formats not captured
- Cap of 20 matches means additional MACs beyond the 20th are silently dropped

## How this service works

Call when an agent needs colon MAC addresses extracted from text, capped at 20 matches. An empty match list is billed. No network. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/regex-mac first.

## Output

A list of up to 20 colon-separated MAC address strings found in the input text (e.g. '00:1A:2B:3C:4D:5E'). If no MAC addresses are present, an empty list is returned — but the call is still billed.
