07 · Questions
Good to know.
More in the FAQ and the documentation, or see how we compare.
What is in the free plan?
1.000 requests a day with full location and network data for IPv4, IPv6 and domains, up to 20 API keys, and no card to sign up. The bot flags come with every paid plan, from 9,00 € a month (VAT included). You can see them for free in the IP lookup.
What can I look up?
Any public IPv4 or IPv6 address, or a domain name. Domains are resolved and the resulting address is looked up.
What do the bot flags mean?
is_ai is true when the address belongs to a known AI crawler or agent operator, is_crawler for a known search or other crawler, and is_scanner for a known internet scanner. A user agent alone never sets a flag, and false is not proof of a human. The bot signals page lists every covered operator.
How precise is the location?
IP geolocation is approximate: country is the most reliable field, while city and coordinates point to an area, never a street address. Fields with no answer say "No Data" instead of guessing.
What happens if I go over my daily limit?
Requests above the limit are refused until the allowance resets at midnight UTC. Paid plans raise the limit, up to 1.000.000 requests a day on Scale. See the plans.
How does billing work?
Every price includes VAT. You can upgrade at any time from the pricing page or your dashboard, and cancel anytime: the plan then runs to the end of the period you paid for. A first purchase can be refunded within 14 days. See subscriptions and billing.
Who runs IPAPI.GR?
Connectivo, a business registered in Greece, in the European Union. Your account data is handled under the GDPR, as set out in the privacy policy. More on the about page.
