About the MAC Address Lookup API

MAC Address Lookup works by retrieving MAC address data a predefined database and providing it in a structured format. The database is updated regularly to ensure accurate and up-to-date information.

What people use it for

Network Security: Use the MAC Address Lookup API to look up MAC address data for network security. Use the data to identify devices, monitor traffic, and prevent unauthorized access
Device Management: Manage devices by using the MAC Address Lookup API to look up MAC address data. Use the data to track devices, assign IP addresses, and troubleshoot network issues
IT Support: Provide IT support by using the MAC Address Lookup API to look up MAC address data. Use the data to diagnose network problems, configure devices, and optimize performance
Network Monitoring: Monitor networks by using the MAC Address Lookup API to look up MAC address data. Use the data to analyze traffic patterns, detect anomalies, and ensure network reliability

Ways to call it

Common questions about the MAC Address Lookup API.

Read the docs →

What does the MAC Address Lookup API do?

MAC Address Lookup is a simple tool for looking up MAC address data. It returns the MAC address vendor, conversions, and more.

How do I authenticate MAC Address Lookup API requests?

Pass your API key in the x-api-key header over HTTPS. One key works across all 300+ APIVerve APIs — there are no per-endpoint credentials.

How much does the MAC Address Lookup API cost?

Each call spends 2 credits from your shared pool. The free tier includes 200 credits every month, and paid plans add more headroom.

How fast is the MAC Address Lookup API?

Response time depends on the endpoint — the p50 through p99 latency for this API is published on this page. Requests are served over HTTPS through a global edge network.

What response formats does the MAC Address Lookup API support?

JSON by default, plus XML and YAML via the format parameter. GraphQL and an MCP interface for AI agents are available across the catalog.

What HTTP method does the MAC Address Lookup API use?

GET over HTTPS, following standard REST conventions with a consistent { status, error, data } response envelope.

Request parameters — GET /v1/macaddresslookup

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

Required

Parameter	Type	Example	Description
`mac`Required	string	`00-B0-D0-63-C2-26`	The MAC address for which you want to get the data (e.g., 00-B0-D0-63-C2-26)

Example request

1
2

curl "https://api.apiverve.com/v1/macaddresslookup?mac=00-B0-D0-63-C2-26" \
  -H "x-api-key: YOUR_API_KEY"

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Header	When	Value
`x-api-key`Required	Every request	Your API key. Header names are case-insensitive, so `X-API-Key` is the same header.
`Authorization`Alternate	Instead of the above	`Bearer <key>` — for clients that only expose bearer auth. Resolves to the same account and the same billing.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Response — GET /v1/macaddresslookup

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Sample response

{
  "status": "ok",
  "error": null,
  "data": {
    "mac": "00:B0:D0:63:C2:26",
    "isValid": true,
    "vendor": "Dell Inc.",
    "oui": "00B0D0",
    "formats": {
      "colon": "00:B0:D0:63:C2:26",
      "dash": "00-B0-D0-63-C2-26",
      "dot": "00.B0.D0.63.C2.26",
      "raw": "00B0D063C226"
    }
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Field	Type	Example	Description
`mac`	string	`"00:B0:D0:63:C2:26"`	The MAC address in standard colon-separated format
`isValid`	boolean	`true`	Whether the MAC address is valid and recognized
`vendor`Premium	string	`"Dell Inc."`	Manufacturer of the device with this MAC address
`oui`Premium	string	`"00B0D0"`	Organizationally Unique Identifier (manufacturer code)
`formats`	object	`{...}`
`colon`	string	`"00:B0:D0:63:C2:26"`	MAC address formatted with colons (00:B0:D0:63:C2:26)
`dash`	string	`"00-B0-D0-63-C2-26"`	MAC address formatted with dashes (00-B0-D0-63-C2-26)
`dot`	string	`"00.B0.D0.63.C2.26"`	MAC address formatted with dots (00.B0.D0.63.C2.26)
`raw`	string	`"00B0D063C226"`	MAC address formatted without separators (00B0D063C226)

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Header	What it carries
`x-api-remaining-credits`	Credits left in the current cycle
`x-api-credits-used`	Credits spent in the current cycle
`x-api-max-credits`	The cycle's allowance
`x-api-version`	Version of the endpoint that answered

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter that has to change.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted here	A key restriction or an IP allow-list — never a bad key.
`429`	Rate limited, or out of credits	Read `error` to tell them apart, then back off or top up.

What a call costs — 2 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Plan	Per month	Credits	MAC Address Lookup calls	Per 1,000 calls
Free	Free	200	100	Free
Starter	$29.99	200,000	100,000	$0.30
Pro	$99.99	1,000,000	500,000	$0.20
Mega	$299.99	4,000,000	2,000,000	$0.15

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.
