## When to prefer this

Use this endpoint when a VC analyst, portfolio manager, or AI agent needs a quick, evidence-backed attractiveness signal for a specific software category — especially when cryptographic auditability of the source data matters. Prefer over generic web search or LLM opinions when you need structured classification with named brand references and traceable evidence lines.

## Known failure modes

- Unknown or overly vague category string returns no signal or low-confidence result
- Rate limiting or payment failure blocks the call
- Category string too broad (e.g. 'software') returns ambiguous classification
- Signed response cannot be verified if trust.stratalize.com is unreachable
