Example prompt: Can you classify my AI system under the EU AI Act? It's a hiring tool that automatically screens and ranks job applicants based on their CVs and interview scores.

## When to prefer this

Choose this endpoint when you need a fast, auditable EU AI Act risk classification for a described AI system without building your own regulatory logic. Ideal for compliance workflows, product reviews, or regulatory due diligence where a cryptographic audit trail is required. Prefer this over general LLM prompting when you need a structured, repeatable classification backed by an audit record.

## Known failure modes

- Missing or empty description parameter returns a validation error
- Description too vague or ambiguous may yield an uncertain or broad classification
- Network timeout on upstream classification model
- Invalid query parameter format returns a 400 error
- Service unavailable returns a 5xx with no classification result

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns an EU AI Act risk classification (e.g. unacceptable risk, high-risk, limited risk, or minimal risk) for the described AI system, along with relevant regulatory obligations and an audit record containing a cryptographic chain hash for traceability.
