API Services

Every capability is exposed through one unified RESTful API; the Tengri LLM and embeddings speak the OpenAI protocol.

Text Translation

High-quality machine translation between Chinese, traditional Mongolian script and Cyrillic Mongolian, with single and batch calls.

Image Translation

OCR and translate Mongolian or Chinese text in images — recognition and translation in a single call.

Document Translation

Layout-preserving translation of entire documents via an async task API, supporting Word, PDF and other common formats.

Webpage Translation

Submit a URL or HTML and get a fully translated page with its structure preserved — ideal for site localization.

Speech Translation

Recognition and translation in one call — audio in, transcript and translation out, via file upload or real-time streaming.

Text-to-Speech

Synthesize natural Mongolian and Chinese speech with multiple voices and adjustable speed, output as MP3 or WAV.

Speech Recognition

Mongolian and Chinese speech-to-text, with audio file transcription and real-time WebSocket streaming.

Pronunciation Assessment

Score Mongolian read-aloud speech on accuracy, fluency and completeness, with word-level feedback.

Dictionary

Query authoritative Mongolian-Chinese dictionaries for structured definitions, parts of speech and example sentences.

Mongolian Encoding Conversion

Batch conversion between Menksoft-style private encodings and Unicode, fixing legacy data corruption.

Glossary

Manage custom term lists to enforce consistent translations of proper nouns — management API is free.

Tengri LLM

Tengri 2 and T1 models with OpenAI-compatible chat completions, streaming output and image/audio/video understanding.

Text Embedding

OpenAI-compatible text embeddings; tengri-embedding-v1 is optimized for Mongolian and other minority languages.
