## 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 gocreative-mac-oui-vendor-lookup-api-89a51098
```

Example prompt: What vendor or manufacturer is associated with the MAC address OUI 00:1A:2B? I need to identify the company that registered that hardware prefix.

## When to prefer this

Use this endpoint when you need to identify the hardware manufacturer or vendor behind a specific MAC address OUI prefix, such as during network asset discovery, device fingerprinting, security audits, or network inventory enrichment. It is particularly useful for AI agents performing automated network analysis without needing to pre-register for an API key.

## Known failure modes

- Invalid or malformed OUI input returns an error
- Unknown or unregistered OUI returns no match
- Payment failure (HTTP 402) if USDC balance is insufficient
- Network timeout if the API is temporarily unavailable
- Malformed path parameter results in 400 or 404 response

## How this service works

Keyless, pay-per-call compliance & regulated-data API for AI agents — OFAC wallet + sanctions/PEP + KYB screening, SEC filings, FRED economics, FDA recalls, federal awards, plus continuous monitoring. USDC on Base/Solana via x402, native MCP. No API key, no signup.

## Output

Returns the vendor or manufacturer name associated with the provided MAC address OUI prefix, drawn from the IEEE OUI registry, identifying which organization registered that block of MAC addresses.
