Modus automatically creates an external API based on the endpoints defined in
your app manifest. Modus generates the API
signature based on the functions you export from your app.
Modus uses the default conventions for each language.
Functions written in Go use starting capital letters to expose functions as public. Modus
creates an external API for public functions from any file that belongs to the main package.The functions below generate an API endpoint with the signature

type Query { classifyText(text: String!, threshold: Float!): String!}
Since the classify function isn’t capitalized, Modus doesn’t include it in the
generated GraphQL API.
