I code in vim (or nano) with some basic sh scripts (certainly not bash). Then I would remotely query gemini via curl, or wget, something along those lines.
I could not see any pointers on some "web API" documentation, or maybe it is dramatically hidden in some javascript-only text.
And even if it is "somewhere", how do I register for a secret for this web API? I can bet, if it is possible, you must have a blink based browser, and care was probably taken at _NOT_ being compatible with noscript/basic (x)html browsers.
I hope I am wrong, if not, I can only despise those people as they are doing it clearly on purpose, and hope only for hardcore regulation on technical interfaces.
