# Language Detection

> Language Detection is a paid API for AI agents from bess-x402.onrender.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-30).

Detects the language of a given text from 55 possible languages, returning per-language probabilities and a reliability flag.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability language-detection-e503c465
```

Example prompt: What language is this text written in: 'Bonjour, comment allez-vous aujourd'hui?' — give me the top language with its probability and whether the detection is reliable.

## When to prefer this

Choose this endpoint when you need fast, probabilistic language identification across a broad set of 55 languages with confidence scores and a reliability flag — especially useful for routing, tagging, or pre-processing pipelines. Prefer this over translation APIs that include language detection only as a side effect when language identification alone is the goal and cost efficiency matters at $0.002 per call.

## Known failure modes

- Very short or single-word texts may yield low reliability scores and ambiguous results
- Highly mixed-language or code-switched text may spread probability across multiple languages without a clear winner
- Texts consisting primarily of numbers, URLs, or punctuation may fail to identify any language reliably
- Empty or whitespace-only text input will likely return an error or null result
- Rare or minority languages not among the 55 supported may be misclassified as a similar supported language

## How this service works

Detect the language of a text among 55 languages, with probabilities for each candidate and a reliability flag. Use to route messages, pick a translator or tag content.

## Output

Returns a ranked list of candidate languages (up to 55) each with a language name, ISO code, and probability score, plus a top-level reliability flag indicating whether the detection is confident or ambiguous.
