Robtex API

Robtex Free API

This API is free to use, however it is limited in rate and amount of data returned. This is to avoid abuse.
We also provide a Professional API for larger volumes.

We are very interested to know what you build with this, if you make something of general interest, please let us know and we can add a link.

The API is (mostly) JSON based and located on https://freeapi.robtex.com/

Robtex PRO API

Syntax is basically the same as for the free API, but there is no ratelimit. The url changes from freeapi.robtex.com to proapi.robtex.com and the API-key is added.

https://freeapi.robtex.com/ipquery/93.184.216.34

https://proapi.robtex.com/ipquery/93.184.216.34?key=X
Replace X with your private API-key. You can see your private key on the dashboard

Current pricing:

ipquery

This API returns the current forward and reverse of an IP number, together with GEO-location data and network data. The format returned is JSON. Most keys are self-explanatory.

status: Should be "ok"
pas: Passive (reverse) DNS
pash: Passive DNS history
act: Active (forward) DNS
acth: Active DNS history

The arrays returned include a timestamp "t" when a record was last seen.
Example query: https://freeapi.robtex.com/ipquery/199.19.54.1

asquery

Returns an array of networks related to a specific AS number. Currently only returns networks actually in global bgp table, but plans are to extend it.
Example query: https://freeapi.robtex.com/asquery/1234

{
   "status": "ok",
   "nets": [
      {
         "n": "132.171.0.0/16",

      {
         "n": "132.171.0.0/17",
         "inbgp": 1
      },
      {
         "n": "132.171.128.0/17",
         "inbgp": 1
      },
      {
         "n": "193.110.32.0/21",
         "inbgp": 1

      }
   ]
}
