ssid.aiAPI

SSID API

Identify the manufacturer behind any MAC address, and know when it's a randomized (private) address instead of a real prefix. No signup for the free tier.

Try it

curl "https://ssid.ai/api/v1/lookup?mac=F4:F5:E8:11:22:33"
{
  "mac": "F4:F5:E8:11:22:33",
  "oui": "F4F5E8",
  "kind": "universal",
  "randomized": false,
  "vendor": { "organization": "Google, Inc.", "address": "..." },
  "deviceType": null,
  "confidence": 1,
  "source": { "name": "IEEE OUI registry", "url": "https://standards-oui.ieee.org/" }
}

Get a key

MAC/OUI lookup is free with no daily limit and needs no key at all. A key raises your per-minute burst headroom and is what the paid router/compliance tiers attach to — no email, shown once.

No email required. Free tier: 1,000 lookups/day. Higher tiers upgrade with the same key.

Auth

Pass an API key to raise limits: Authorization: Bearer ssid_… (or x-api-key). Every response carries X-RateLimit-* headers.

Starter$10 / mo10,000 / day120 / min
Pro$100 / mo100,000 / day300 / min

The burst ceiling scales with the tier so the daily figure stays reachable; your ceiling comes back on every response in X-RateLimit-Burst. Full terms, and when a cheaper option is the right call, on pricing.

Upgrade

Checkout and card handling run on Stripe — your card never touches ssid.ai. The upgraded limit applies to this key within a minute of payment. Cancel any time from Manage billing; the key drops back to the free tier at period end.

Stuck, or something went wrong during checkout? Email support@ssid.ai and a person will answer. Volume beyond Pro or data licensing: hello@ssid.ai. Refunds per the terms.
