Technical details
Endpoint
GEThttps://api.x402node.dev/text/lang-detectWhen to prefer
Use this endpoint when you need fast, per-call language identification of arbitrary text with an ISO 639-3 code and confidence score — especially useful in multilingual AI pipelines, content routing systems, or translation preprocessing where you need a standardized language tag rather than a human-readable label.
Side effects
- Very short text (1-2 characters) may yield low confidence or unreliable detection
- Mixed-language text may return the dominant language but with reduced confidence
- Unknown or constructed languages not in the 80+ supported set may return a closest match with low confidence
- Empty or whitespace-only input may return an error or null language code
- Heavily romanized or transliterated text may be misclassified
