# MAC Address Generator (EUI-48)

> MAC Address Generator (EUI-48) is a paid API for AI agents from macaddress.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Generates a random EUI-48 MAC address with configurable locally-administered/universal and unicast/multicast bit settings.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-generator-eui-48-f7563f84 -d '<json body>'
```

Example prompt: Generate a random locally-administered unicast MAC address I can use for testing — make it safe for a private network.

## When to prefer this

Choose this endpoint when you need a quick, correctly-formatted random EUI-48 MAC address with explicit control over the U/L and I/G bits — especially for network testing, VM provisioning, or generating safe dummy addresses that won't collide with real OUI-registered hardware. Pair with sibling endpoints on macaddress.openverbs.com for reformatting, parsing, or EUI-64 derivation.

## Known failure modes

- Invalid boolean values for 'local' or 'multicast' fields may return a 400 validation error
- Network timeout if the service is temporarily unavailable
- Payment failure if insufficient USDC balance for the $0.002 per-call fee via x402 protocol

## How this service works

Generate a random EUI-48 MAC address. By default it is locally-administered and unicast (safe for testing); set `local:false` for a universal-bit address or `multicast:true` for a group address.

## Output

Returns a randomly generated EUI-48 MAC address with the U/L (locally-administered) and I/G (unicast/multicast) bits configured according to the request parameters. The address is suitable for use in network testing, virtual machines, or any context requiring a valid MAC address format.
