Keys are stored in this browser only. A key lets you buy credits and keep going after the free runs.
How it works
- Type a domain name, IP address, or AS number into the query field and choose compact or full output.
- Press Run to send the query to the registry's RDAP service.
- Read the normalised registration record in the result panel, or copy the JSON for use elsewhere.
Limits
Each query must fit within 4,096 bytes. You get 20 free lookups per day without a login. After that, each run costs 1 credit drawn from a prepaid balance attached to your API key.
Privacy
Your query is used only to fulfil the request and is discarded afterwards; it is not retained or used for any other purpose. Usage records store only the time, tool name, status, duration, credits consumed, and a salted hash of your IP address.
