Example prompt: Can you run a length and paragraph profile on this research note I've written? Here's the full text in Markdown — I want to see the word count, paragraph count, and structural breakdown.

## When to prefer this

Choose this endpoint when you need a fast, deterministic structural analysis of a research note document — specifically word count, paragraph count, and length profile — without any generative AI output or fact-checking. Prefer this over general-purpose LLM analysis when you need consistent, reproducible metrics for document QA pipelines or submission checklists.

## Known failure modes

- Input text exceeds 20,000 character limit — request will be rejected
- Empty or missing text field — no profile can be generated
- Malformed Markdown may affect paragraph detection accuracy
- Payment of 0.01 USDC not completed — endpoint returns 402 Payment Required
