Example prompt: Can you pull out all the action-marker lines (like TODOs with dates) from this research note? Here's the markdown: '## Findings
Content here.
TODO: review the supplied document by 2026-10-10.'

## When to prefer this

Choose this endpoint when you need deterministic, rule-based extraction of action-marker lines (such as TODO annotations with dates) from a research note formatted in Markdown or plain text, and do not need generative summarization or AI-written prose — especially when cost predictability ($0.01 USDC per call) and bounded processing are priorities.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- No action-marker lines found in the document — empty result returned
- Malformed or empty input text — processing error
- Payment not completed — endpoint returns 402
