You can give a Roblox game real generated text — dialogue, quests, item names — with a single HTTP request. The catch is where you make it.
HttpService, from the server only
local HttpService = game:GetService("HttpService")
local ok, res = pcall(function()
return HttpService:PostAsync(ENDPOINT, HttpService:JSONEncode({
system = "You are a wise shopkeeper. One sentence.",
text = "what do you sell?",
}), Enum.HttpContentType.ApplicationJson, false, { Authorization = "Bearer " .. KEY })
end)
Turn on Game Settings → Security → Allow HTTP Requests first, or every call fails.
The limits you will hit
- 500 requests/min per server. Cache repeated prompts so you don't burn the budget.
- No SSE streaming in live games. Streaming only works in Studio; live servers are request/response.
- Moderation. Anything player-facing must be filtered, or your game risks removal.
A shortcut
The Cortex kit wraps all of this — one key, caching, retries, and moderation on by default, billed in Robux instead of a credit card. But the pattern above works with any backend. Open source: https://github.com/cortex-rbx/roblox-ai-kit
