How this service works
Detects the dominant language of a text (over 100 languages) with Amazon Comprehend, from its first 1000 characters. Returns the most likely language codes with scores.
Output
Returns an array of detected language candidates, each with an ISO 639-1 language code (e.g. 'en', 'fr', 'de') and a confidence score between 0 and 1, ordered from most to least likely. The analysis is based on the first 1000 characters of the input text.
Example use cases
Route multilingual customer tickets
“I have an incoming support ticket that says 'Necesito ayuda con mi pedido' — can you detect what language it's in so I can route it to the right team?”
Validate user profile language field
“A user just submitted a bio that reads 'Ich bin ein Berliner und liebe Musik' — can you detect what language that is so I can tag their profile correctly?”
Pre-detect language before translation
“Before I translate this paragraph, can you tell me what language it's in? Here's the text: '今日は東京でとても暑いです。'”
Technical details
Endpoint
POSThttps://ai.kagurazaka.dev/v1/language?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, automated language identification across 100+ languages backed by Amazon Comprehend's production NLP infrastructure. Ideal for preprocessing pipelines that route, tag, or translate multilingual content, and when you need confidence scores rather than a binary yes/no answer. Prefer this over translation endpoints when language identification alone is the goal, or when you need to validate that user input matches an expected locale.
Side effects
- Empty or very short text may result in low-confidence or ambiguous language detection
- Text shorter than a few words may yield unreliable results
- Highly mixed-language input may split confidence across multiple languages
- Payment failure (402) if USDC balance is insufficient
- Request rejected if text field is missing or malformed JSON
