Example prompt: Can you classify this AI system under the EU AI Act and tell me its risk level? It's a CV screening tool that automatically filters job applicants based on predicted performance scores.

## When to prefer this

Use this endpoint when you need a fast, rule-based EU AI Act compliance check for an AI system description without engaging a human legal expert. Ideal for initial triage, developer compliance checks, or automated regulatory screening pipelines. Prefer this over general LLM reasoning when you need structured, citation-backed output tied to specific EU AI Act articles and annexes.

## Known failure modes

- Missing or empty description query parameter returns validation error
- Vague description may yield ambiguous or low-confidence classification
- Service unavailable returns HTTP 402 or 5xx error
- Description too short to match against regulatory criteria may return minimal-risk by default

## How this service works

Classify an AI system's risk level under the EU AI Act. Rule-based analysis against Annex III and Article 5/6/50 criteria.

## Output

Returns a structured risk classification indicating the AI system's risk level (e.g. unacceptable, high-risk, limited-risk, minimal-risk) under the EU AI Act, with references to the specific Annex III categories or Article 5/6/50 criteria that triggered the classification.
