## When to prefer this

Choose this endpoint when you need a quick, AI-generated RESTful endpoint name suggestion from a plain-English description and want a pay-per-call approach with no signup. Useful for code generators, API documentation tools, or developer assistants that need to auto-label routes. Prefer this over general-purpose LLMs when you want a purpose-built, lightweight, cheap ($0.001 USDC) call that doesn't require managing API keys.

## Known failure modes

- Empty or too-short description input (minLength: 1 enforced) — returns validation error
- Description exceeding 500 characters (maxLength enforced) — returns validation error
- Ambiguous or overly generic description may yield a generic or unhelpful endpoint name
- Payment not included or insufficient — returns HTTP 402 Payment Required
- Service unavailable or model not loaded — returns 5xx error
