Response fields

A successful call returns:

Copy

Field	Description
origin	Your original input text.
translated	The translated result.
reversed	Back-translation of the result into the source language, for your own spot-checking. Only present when back-translation is enabled server-side; otherwise null.
from / to	Source and target language codes.
detected_from	The auto-detected source language — set only when you omitted "from" from the request.
engine	Always "ugajapa-bot" — the actual engine used internally is not exposed.
cached	Whether this exact request was served from the shared cache instead of a fresh translation.
characters_used	Characters counted against your monthly quota for this request.
quality	Quality-evaluation details (see the rows below) — AI review and the back-translation heuristic run independently and may both be present.
quality.ai	AI semantic review: {"score", "passed"}, 0.0–1.0. null if no AI provider (OpenAI/Groq) is configured, or the call failed.
quality.back_translation	Word-overlap score against a back-translation: {"score"}, 0.0–1.0. null unless back-translation is enabled server-side for this request.
quality.overall	The resolved score used for pass/fail and sorting — quality.ai's score when present, else quality.back_translation's, else null.
quality.label / quality.color	A "Good" / "Fair" / "Low" / "Unknown" label with a suggested UI color ("green" / "amber" / "red" / "gray").
quality.passed	Whether the translation met the quality threshold. null when no evaluation ran at all.
quality.method	Which evaluation(s) actually ran: "ai", "heuristic", "ai+heuristic", or "none".
quality.review_reason	Explanation when quality failed, written in the source text's language. null when passed or no evaluation ran.
quality.review_reason_code	Machine-readable category: "ai_specific", "ai_unspecified", or "heuristic_low_overlap". null when passed or no evaluation ran. Only the two fixed-message codes need localizing on your end — "ai_specific" text is already written in your source language.

Name	Key	Created	Last used	Status	Cache

Cache on: an identical repeat translation (same text, same language pair) returns instantly without a new engine call — character usage and billing are the same either way, so this is purely a speed optimization. Cache off: every request is translated fresh and the text is never held in the shared cache, even briefly — turn this off if you don't want translation content sitting in server memory at all, even temporarily.
