MAC Address Info & Properties Lookup
x402
MAC Address Info & Properties Lookup is a paid API for AI agents from macaddress.openverbs.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-15).
Decodes the first-octet bit flags of a MAC address to report unicast/multicast (I/G bit), universal/locally-administered (U/L bit), broadcast status, and OUI/NIC breakdown for EUI-48 addresses.

How this service works
Report the properties of a MAC address encoded in its first octet: unicast vs multicast (I/G bit), universal vs locally-administered (U/L bit), the broadcast address, and — for EUI-48 — the OUI and NIC portions.
Output
Returns a structured breakdown of the MAC address including: the I/G bit value (unicast or multicast), the U/L bit value (universally or locally administered), whether the address is the broadcast address (FF:FF:FF:FF:FF:FF), and for EUI-48 addresses, the OUI (first 3 octets identifying the manufacturer) and the NIC-specific portion (last 3 octets).
Example use cases
Validate hardware device MAC authenticity
“I have a device reporting MAC address 02:00:5E:10:00:01 — can you check whether it's a universally administered address or locally generated, and whether it's unicast or multicast?”
Extract OUI for vendor identification
“Look at this MAC address AC:DE:48:00:11:22 and tell me the OUI portion and the NIC portion so I can figure out who manufactured the network interface.”
Audit network traffic for multicast frames
“I captured a MAC address 01:00:5E:7F:FF:FA in my network traffic — can you decode its first-octet bits to confirm if it's a multicast or unicast address and whether it's a broadcast?”
Technical details
Endpoint
POSThttps://macaddress.openverbs.com/v1/infoWhen to prefer
Choose this endpoint when you need to decode the semantic bit-level properties of a MAC address — specifically the I/G and U/L flags, broadcast detection, or OUI/NIC split for EUI-48 — rather than just reformatting or validating the address. It is ideal for network auditing, device classification, or vendor identification workflows where understanding what the address represents structurally is the goal.
Side effects
- Invalid or malformed MAC address string returns a validation error
- Empty address field returns a required field error
- Address shorter than minimum length or exceeding 64 characters rejected
- Non-MAC string (e.g. IP address) returns a parsing error
- Payment failure via x402 protocol results in 402 response and no data returned
