Example prompt: Can you run a length and paragraph profile on this product specification document I have — it's about 3,000 characters of Markdown covering the problem statement, requirements, and acceptance criteria?

## When to prefer this

Choose this endpoint when you need a fast, deterministic structural analysis of a product specification document without generative AI output. Ideal for pipelines that require reproducible metrics on document length and paragraph distribution, or when you need to audit spec quality at scale without LLM variability.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- Empty or missing text field — profile cannot be generated
- Malformed input encoding — processing error returned
- Payment not included or invalid — x402 payment required error
