## When to prefer this

Choose this endpoint when you need a deterministic, structured extraction of all numeric tokens from a newsletter document — particularly for fact-checking, compliance auditing, or editorial review workflows. It is preferable to generative AI text analysis when you need consistent, repeatable results without hallucination risk. Best suited for Markdown or plain-text newsletter content up to 20,000 characters.

## Known failure modes

- Input text exceeds 20,000 character limit — request will be rejected or truncated
- Empty or whitespace-only text input returns an empty inventory
- Non-numeric content only returns an empty token list
- Ambiguous number formats (e.g. locale-specific punctuation) may be misclassified
- Service unavailable or payment not processed — HTTP 402 or 5xx error
