oh thanks. It was just some toy I made playing with golang and tries a few years back. It uses some linux word file as input, I just forget which. From memory, I think these are all the endpoints...

  /startswith/xyz
  /endswith/xyz
  /contains/xyz
  /anagrams/xyz  - exact match anagrams
  /canmake/xyz - all words that can be made with that combination of letters

What I do when looking for words is go to `/usr/share/dict/` and grep for things, for example `grep 'su$' american-english` gives me:

  Amaterasu
  Fujitsu
  Ginsu
  Ieyasu
  Iguassu
  jujitsu
  shiatsu
  tiramisu
