@ronaldtse the lambda now support interscript v0.1.4, you can test it as sample bellow

curl "https://api.interscript.com" \
 -i \
 -X 'POST' \
 -H 'Accept: application/json, text/plain, */*' \
 -H 'Content-Type: application/json' \
 -H 'Origin: http://localhost:3000' \
 --data-binary '{transliterate(systemCode: "bgnpcgn-arm-Armn-Latn-1981", input: "Հայերէն")}'

@phuonghuynh can you help document how to use the API in the README? Will make a new issue for this.
