Got API?
Rest assured, there’s an API. If you enjoy haggling, feel free to handle your own content negotiation and if negotiation isn’t your thing, we’ve got you covered.
Pick any word, pick your format (via file extension or Accept header), and pick your tool. The snippet updates live with copy buttons throughout.
Lookup word
Formats
- .json application/json
- .html text/html

Format selection — pick a method
# extension approach https://defs.my/flash.txt
Examples by tool
curl "https://defs.my/flash.txt"
Two ways to request a format — append .json / .html / .xml / .md / .txt to the URL, or send a content negotiation header like Accept: text/markdown to the bare URL (e.g. defs.my/flash).
