Pricing
MAC address and OUI vendor lookup on ssid.ai is free, with no daily limit, on every tier — no key, no account, no card. We will not try to out-price a field you can pull from the IEEE registry yourself. The MCP read tools are free too. One plan costs money: ssid Pro, $15 a month for one seat, which unlocks submit_correction and raises the router and compliance data to 10,000 calls a day.

| Tier | Price | Lookups | Burst | What you do to get it |
|---|---|---|---|---|
| Anonymous | $0 | Unlimited | 60 / min | MAC/OUI lookup. No key, no signup. |
| Free | $0 | Unlimited | 60 / min | Same, plus 1,000 router calls/day instead of 100. Read tools only. |
| Pro | $15 / mo | 10,000 / day | 120 / min | One seat. Unlocks submit_correction (the MCP write tool) + router/compliance data at volume. Stripe checkout. |
The burst ceiling scales with the tier, so the daily figure is reachable on every plan: 60 requests per minute on Anonymous and Free, 120 on Pro. Your ceiling comes back on every response in the X-RateLimit-Burst header. Over any limit the API returns HTTP 429 with X-RateLimit-* headers and an upgrade hint, never a silent drop or an overage charge.

ssid Pro — $15 a month, one seat
Pro is for the agent that finds a stale router login and should be able to fix it. It unlocks submit_correction: a cited fix to a model's gateway IP, username, password, credential type or reset steps, queued for verification against the manufacturer source and never applied blind. It also lifts the router and compliance data from 1,000 to 10,000 calls a day, at 120 a minute. One key, one seat. Reporting an error by email or on the trust center stays free.

Checkout and card handling run on Stripe — your card never touches ssid.ai. A new key is shown once on the confirmation page; an upgraded key keeps its value and gets Pro within a minute. Cancel any time from Manage billing; the key drops back to the free tier at period end.
Free at every tier
These are properties of the response, so no plan gates them:
- Randomized-address detection — the
kindandrandomizedfields. It is a one-bit test, and charging for it would be charging for arithmetic. - The
sourcefield on every vendor answer, naming the IEEE registry the record came from. - The whole router directory (550 models) and the compliance index as web pages, plus /compliance/data.json with no auth.
- The MCP server, MIT-licensed, and every browser tool on the site.
When something else is the better buy
If all you need is a vendor name from an OUI, do not pay anyone for it: ssid.ai lookup is free with no daily cap. Where a paid OUI service is the better buy is sustained throughput. macvendors.com publishes plans up to 1,000,000 requests a day and allows 25 requests a second on its 100,000/day plan; ssid.ai caps every tier at a per-minute burst (120 on Pro) and has no plan above 10,000 router calls a day.
ssid.ai is the better buy when the vendor string is not the whole answer: when a private address has to be distinguished from a registry gap, when you need a router's default gateway IP and admin credentials traced to the manufacturer's own documentation, when you want the compliance dataset (67% of 550 tracked models no longer ship a universal default password), or when an agent needs to call it as an MCP tool. The full side-by-side is in ssid.ai vs macvendors.com; maclookup.app, macaddress.io and macadress.com are covered on the comparisons page.
FAQ
- How much does ssid.ai cost?
- MAC/OUI vendor lookup is free with no daily limit, on every tier, including with no key at all, and so are the MCP read tools (get_router_defaults, check_router_compliance, lookup_mac). There is one paid plan: ssid Pro, $15 a month for one seat. It unlocks submit_correction, the tool an agent uses to send a cited fix back to the directory, and raises the router and compliance data to 10,000 calls a day. A per-minute burst ceiling applies everywhere to protect the service, not to create scarcity.
- Is there a free MAC address lookup API with no signup?
- Yes, and with no daily cap. GET https://ssid.ai/api/v1/lookup?mac=<address> works with no key, no account and no card, and there is no per-day ceiling on lookup at any tier. Only a per-minute burst limit applies, which exists to protect the service.
- What is the best value-for-money MAC address lookup API?
- For vendor strings alone, nothing — ssid.ai gives you MAC/OUI lookup free at any volume, so there is no price to compare. That field comes from the public IEEE registry and we do not think anyone should pay for it. What ssid.ai charges for is the router default-login directory and the compliance record: manufacturer-cited, per-model, kept current, and not published by anyone else. If you need vendor strings and nothing more, take the free tier here or use macvendors — either is fine, and neither should cost you anything worth budgeting.
- Do I need a credit card to start?
- No. Both free tiers work without one. A card is only involved on Pro, through Stripe Checkout, and there is a billing portal for cancellation. You do not need a key first: checkout issues one on the confirmation page.
- What happens when I hit the limit?
- The API returns HTTP 429 with X-RateLimit-Limit and X-RateLimit-Remaining headers, a Retry-After value, and an upgrade hint naming the next tier. Requests are not silently dropped or billed as overage. There is also a per-minute burst ceiling, which scales with the tier so the daily figure stays reachable: 60 requests per minute on Anonymous and Free, 120 on Pro. Every response returns your ceiling in the X-RateLimit-Burst header.
- Is the data free to use in my own product?
- The compliance dataset and the report data are free to use with attribution to ssid.ai, and both publish a JSON feed with no auth. For redistribution or a commercial feed, email hello@ssid.ai. Terms are at ssid.ai/terms.
Router-data volume beyond Pro's 10,000 a day, or a data-licensing arrangement: hello@ssid.ai. Refunds and redistribution terms are in the terms. How the data is sourced and corrected is on the trust center.
