## When to prefer this

Choose this endpoint when you need a deterministic, structured extraction of ISO-date patterns (YYYY-MM-DD) from a user guide or technical document. It is purpose-built for documentation workflows rather than general-purpose NLP date extraction. Prefer it when you need consistent, reproducible results on markdown or plain text up to 20,000 characters and do not need generative summarization or fact-checking alongside the date extraction.

## Known failure modes

- Text exceeds 20,000 character limit — request is rejected
- No ISO-date patterns found in the document — returns an empty inventory
- Malformed or non-text input — may return an error or empty result
- Non-ISO date formats (e.g. MM/DD/YYYY, 'October 10') are not extracted and will be absent from the inventory
