+# DOMAPI - Domain API, basic management
+
+DOMAPI is a quick and simple API to get properties of a domain name.
+
+## Key features
+
+* Purely Python
+* It's an API with 5 endpoints
+* Needs flask library
+* Needs wordsegment library
+* Needs python-whois library
+* Needs tldextract library
+
+## Requirements
+
+DOMAPI requires install next Python libraries with pip:
+
+* pip install flask
+* pip install wordsegment
+* pip install python-whois
+* pip install tldextract
+
+## Usage
+
+- Run: python .\wodapi.py
+- Then, a server is deploy on http://127.0.0.1:5000
+- Use GET with endpoints
+- An error will occur if your parameter is not a well-formed domain.
+
+## Endpoints
+
+- words :: split a domain name in words. Only in English languaje, next versions will be available in other languages. Example: http://127.0.0.1:5000/words/hereyourdomainname.com
+- whois :: return full whois info from domain. It works with many extensions, although some have limitations in use, such as the .NET extension. Example: http://127.0.0.1:5000/whois/hereyourdomainname.com
+- tld :: return TLD or ccTLD or a domain. Example: http://127.0.0.1:5000/tld/hereyourdomainname.com
+- domain :: return only domain of a full domain. Example: http://127.0.0.1:5000/domain/hereyourdomainname.com
+- size :: returns the size of a domain, not counting its extension. Example: http://127.0.0.1:5000/size/hereyourdomainname.com
+
+## TO-DO
+
+- words in Italian and Spanish
+- test if a domain is IDN
+- conver between ascii-punycode-idn
