Language detector / language identification. ISO 639-1 code, full name, confidence (0-1). Mixed-language detection with secondary languages list. 100+ languages.
Output
Returns the detected primary language as an ISO 639-1 code (e.g. 'fr') and full name (e.g. 'French'), a confidence score between 0 and 1, and a list of secondary languages if the text contains mixed-language content. Supports 100+ languages.
Example use cases
Example prompt

Technical details
Endpoint
POSThttps://x402-deployer.x402-deployer.workers.dev/detect-languageWhen to prefer
Use this endpoint when you need programmatic language identification with a confidence score and ISO 639-1 codes, especially for multilingual or mixed-language text. Ideal for routing user messages by language, pre-processing text before translation, or filtering content by language in pipelines.
Side effects
- Empty or very short text may yield low confidence or ambiguous results
- Highly transliterated or code-switched text may misidentify the primary language
- Extremely rare languages may not be detected correctly or may fall back to a closest match
- Non-textual input or binary content will likely return an error or near-zero confidence
