# CoCo Language Detection API

> CoCo Language Detection API is a paid API for AI agents from cocoeatsai.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).

Detects the natural language of a given text string and returns the identified language code with confidence score

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 coco-language-detection-api-fd08d9d0
```

Example prompt: Can you detect what language this text is written in: 'Bonjour, comment ça va?'

## When to prefer this

Use this endpoint when you need lightweight, fast language detection on a text snippet and want a simple JSON response with a language code and confidence score. It is ideal for pre-processing pipelines, routing decisions, or validating user input language before forwarding to a translation or localization service. Prefer it for single-text, low-latency detection calls where the $0.001 per-call pricing is acceptable.

## Known failure modes

- Empty or missing text query parameter returns an error or undefined behavior
- Very short text (single character or word) may yield low confidence or incorrect detection
- Highly mixed-language text may produce ambiguous results with split confidence across candidates
- Extremely rare or constructed languages may not be recognized
- Request timeout if upstream service is unavailable

## Output

Returns a JSON object containing the detected language code (e.g. 'en' for English), a confidence score between 0 and 1, and an array of candidate languages each with a probability score. Example: {"language":"en","candidates":[{"p":1,"lang":"en"}],"confidence":1}
