Question 1

Is the Free tier really free? Do I need to sign up?

Accepted Answer

Yes. Free gives you 1,000 requests/day per IP address with no signup and no API key. Create an account only if you want a key, usage tracking, or to upgrade.

Question 2

What counts as one request?

Accepted Answer

One API call is one request, including a search-bar search or MCP tool call that fans out to several checks behind the scenes. Bulk lookups are charged per item (each IP in a POST /v1/ip/bulk counts), and nearby places and premium phone lookups have their own separate budgets.

Question 3

What happens if I go over my daily limit?

Accepted Answer

Requests return HTTP 429 with a Retry-After header until the window resets at 00:00 UTC, or until you move to a higher tier. Nothing breaks on your side beyond those rejected calls.

Question 4

Is city-level geolocation or IPv6 locked to paid plans?

Accepted Answer

City, postal code, and latitude/longitude are returned at every tier, including Free, and IPv6 addresses are supported too — paid tiers raise your volume and add bulk lookup, support, and an SLA rather than gating location precision.

Question 5

Do carrier and porting phone lookups cost extra?

Accepted Answer

No. Premium phone lookups are included in every plan — 100 per month on Free, 1,000 on Pro, and 5,000 on Enterprise. Once you use them up you keep getting the free format/region/line-type result for the rest of the month.
