How this service works
Language detection: identify which of 20 common languages (or "other") a text is written in, with a confidence score. Powered by Jev, with an automatic Groq-hosted LLM fallback if Jev is slow or unavailable - under 4.5s guaranteed. Try GET /language/sample.
Output
Returns a language label (e.g. 'French', 'Spanish', 'other') and a numeric confidence score indicating how certain the model is about the detected language.
Example use cases
Routing multilingual customer support tickets
“Figure out what language this customer message is written in so I can route it to the right support team: 'Necesito ayuda con mi pedido, no ha llegado todavía.'”
Content moderation language gating
“Before I run moderation on this user post, tell me what language it's in and your confidence level: 'Questo prodotto è assolutamente fantastico, lo consiglio a tutti!'”
Auto-tagging uploaded documents by language
“I just uploaded a document — can you identify what language it's written in? Here's the first paragraph: 'Die Sonne scheint heute besonders hell über den Bergen.'”
Technical details
Endpoint
GEThttps://x402.agentindex.world/language?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, cheap, per-call language detection with a confidence score and a guaranteed sub-4.5s response time. Ideal for classifying short-to-medium texts (up to 4000 characters) in pipelines where cost per call matters and you need the reliability of a dual-engine fallback (Jev + Groq LLM). Not ideal for bulk batch jobs or for detecting rare languages outside the 20 supported.
Side effects
- Text exceeds 4000 characters — truncation or rejection required
- Very short or ambiguous text may yield low confidence scores or 'other'
- Language not among the 20 supported returns 'other' rather than a specific label
- Jev and LLM fallback both unavailable — request times out beyond 4.5s SLA
- Payment failure or insufficient USDC balance blocks the call
