## 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 ai-generated-text-detector-for-european-portuguese-pt-pt-5135aac4 -d '<json body>'
```

Example prompt: Can you check whether this European Portuguese text was likely written by AI or a human? Here's the text: 'A inteligência artificial está a transformar profundamente a sociedade moderna, trazendo consigo oportunidades e desafios sem precedentes para o mercado de trabalho e para a educação.'

## When to prefer this

Choose this endpoint when you specifically need to detect AI-generated content written in European Portuguese (PT-PT), not Brazilian Portuguese (PT-BR) or other languages. It is calibrated on European Portuguese corpora and achieves AUROC 0.94 with only 1.7% false accusations, making it well-suited for academic integrity, publishing, and HR screening use cases where false positives are costly. Prefer this over generic multilingual AI detectors when European Portuguese accuracy is a priority.

## Known failure modes

- Text shorter than recommended 90 words may yield less reliable probability estimates
- Text submitted in non-Portuguese or Brazilian Portuguese (PT-BR) may reduce accuracy
- Input text exceeding 8000 characters will be rejected
- Non-HTTP method body types or unsupported HTTP methods will cause validation errors
- Network or service unavailability returns a 5xx error

## How this service works

AI-generated text detector for European Portuguese (PT-PT): Binoculars method calibrated on Portuguese texts (AUROC 0.94, 1.7% false accusations). Returns a probability level, never proof. Text is not stored.

## Output

Returns a probability level indicating how likely the submitted European Portuguese text is to have been AI-generated, based on the Binoculars method calibrated on Portuguese corpora (AUROC 0.94, ~1.7% false positive rate). The result is a probability/confidence level, not definitive proof. Text is not stored after analysis.
