How it works

  1. Choose a plan

    Free needs only an NSN Lookup account. Paid plans are a monthly subscription.

  2. Get your key

    Your API key appears on your account page, next to your other NSN Lookup subscriptions.

  3. Make calls

    Send the key in a header. REST calls and MCP calls both count toward your plan.

Pricing questions

What counts as a request?
Each call to a data endpoint, and each MCP tool call, is one request. The documentation pages and the health and version checks are free and need no key.
What happens if I reach my limit?
Calls are refused with a clear 429 response until the limit resets. You are never charged extra automatically. You can upgrade at any time from your account page.
Can I change or cancel my plan?
Yes. Manage API subscriptions from your account page, together with your other NSN Lookup subscriptions.
Do you offer government or volume pricing?
Yes. Contact us with your expected volume.
Is there a trial of the paid plans?
The Free plan has every feature of the paid plans, at a lower volume, for as long as you like.

Not sure which plan fits?

Start on Free. Your account page shows how many requests you use, so the right plan becomes obvious.
