Generate text

POST https://api.dhanu.ai/api/pub/v1/text

Generates text from a prompt. Nothing is stored — no task, no document, no version history. You get the text back and a metering record is written against the acting project.

Request

Field	Type	Required	Notes
prompt	string	Yes	Up to 2000 characters
system	string	No	System instruction shaping the reply
maxTokens	number	No	Caps the length of the reply
projectId	string	No	Required when the key is scoped to more than one project

  "text": "…",
  "model": "…",
  "usage": { "inputTokens": 12, "outputTokens": 41 },
  "cost": { "amount": 28, "currency": "NPR" }
}

cost.amount is in the currency’s minor unit, so 28 is NPR 0.28. A reply of roughly 500 tokens in and 500 out costs on the order of 28 paisa.
