WhoisXML API Blog

Getting JSON Lines from an API Call into a CSV File via UNIX Command Line

WhoisXML API offers, via API calls, a lot of information on domains or IP addresses that is very useful for a number of applications, including cybersecurity investigations, domain appraisal or system administration. Imagine that one is given a long list of domain names, and one is interested in each domain's details, e.g., WHOIS or website categories, etc. In each API call, a single domain name is sent, and its data is returned in JSON format. (Some of the APIs of WhoisXML API offer bulk lookups, too, but we will not deal with this possibility here.) To get an overview of the data, analysts often prefer to have everything in a single csv file; one line for each domain. This can be opened by popular office spreadsheets like Excel or LibreOffice Calc, or sent to other kinds of processing.

OWASP Amass and WhoisXML API Are Now Integration Partners

Access to relevant data is extremely valuable in today’s information-driven environment. That is especially true in the realm of attack surface mapping. By getting a sense of attack surfaces through asset discovery processes for vulnerability management, organizations can assess their security posture and better protect themselves against external attacks.

Attack surface mapping may seem like a lot of work, but cybersecurity experts don’t have to go at it alone. Many members of the cybersecurity community are linked through the Open Web Application Security Project® (OWASP) Foundation, a nonprofit organization that aims to improve software security. The OWASP Amass Project, meanwhile, embodies the community’s synergistic and collaborative effort.
