Passive DNS API

The Passive DNS API facilitates queriese into the Spamhaus Passive DNS database via HTTPS GET commands. Two parameters, and opitionally a third must be sent to the server to make a query.

Parameters

	*queryType - The type of query you are making
	*target - The record you are searching for
	*output (optional) - The format the response comes back in.

Supported queryType:

queryType Description
CHECK_QUOTA Query to find information regarding your quotas
IP Query an IP/CIDR for hostnames
HOSTDOM Query an IP/CIDR for domains
HOST Query a hostname for IP addresses
NS Query a nameserver for authoritative domains
DOMAIN Query a domain for authoritative nameservers
DOMSEARCH Query a domain for associated hosts
MXD Query a host/domain for its MX records
MX Query an MX target for all clients
CNAME Query canonical names for a host/domain
CHOST Query a host/domain for CNAME records
TXT Query a host/domain for TXT records
SOA Query a domain for a SOA record
NEW_DOMAIN Query a domain for the first time it was seen

Supported output

output= Description
CSV A pipe ("|") separated list (default)
JSON A series of JSON objects, one for each result
JOBJECT A singular JSON object

Example Output URL

To query the IP address 192.168.0.1, with the return format of CSV, create a url with “queryType=ip”, “target=192.168.0.1”, “output=csv”. https://pdnsapi.deteque.com/api/query?queryType=IP&target=192.168.0.1&output=csv

Note: The default output is CSV, so it will return as CSV without the output specified as well.

Optional Query Limit

The default query limit is 100,000 records. If the “query_limit” parameter is set the maximum number of records can be changed to lower the volume. A higher query limit cannot be used.

Example Query Limit URL

https://pdnsapi.deteque.com/api/query?queryType=IP&target=192.168.0.1&query_limit=1000

Example Curl Command

On the CLI a simple Curl command can be used to access the API using this syntax:

url --user <user>:<password> "https://pdnsapi.deteque.com/api/query?queryType=IP&target=192.168.0.1&output=csv"

Query Type CHECK_QUOTA

This query type shows how many queries your company has done for the day and month, as well as how many queries you are allowed in total for those time periods. This query type does not require the “target” parameter and only has the output in a JSON object format. This query will not be included in your daily/monthly query allowance.

Output:

{
	"User": "example", 
	"CustomerID": "11111111",
	"DailyQueries": 7854,
	"DailyQuota": 10000000,

	"MonthlyQuota": 100000000
}

Query Type IP

This query type is used to identify hosts seen on a given IP address or within a given subnet. The largest subnet queryable is a /16 for IPv4 or /32 for IPv6. All results will return the “last seen” instance for each host, sorted in alphabetical order by host.

Sample type IP queries would be:

	target=192.168.0.1
