npm install
npm run dev

Once running, head to http://localhost:5173/api/dev

Enter a url formatted like http://localhost:5173/api/{castHash}

E.g. http://localhost:5173/api/0xefce3c6093a361124976bcf67fe4acd87f015133

The cast hash should be for a cast with the text @launcher launch $[TICKER]

If the cast contains an image, it will pull it into the frame for the token launch.
