Example prompt: Can you mask all the email addresses and phone numbers in this user guide draft before we publish it? Here's the Markdown content: '## Overview\nContact support at help@example.com or call 555-123-4567 for assistance.'

## When to prefer this

Choose this endpoint when you need deterministic, rule-based masking of email and phone contact patterns in user guide documents (Markdown or plain text), especially for privacy compliance, publishing sanitization, or vendor sharing workflows. It is not generative — it applies fixed pattern masking without AI prose generation or fact-checking, making it predictable and auditable. Prefer it over general-purpose LLM redaction when you need consistent, bounded output for a single document up to 20,000 characters.

## Known failure modes

- Input text exceeds 20,000 character limit, resulting in rejection
- Malformed or ambiguous phone patterns may not be detected and masked
- Non-standard international phone formats may be missed
- Empty or missing text field may return an error or empty result
- Service unavailability due to infrastructure issues
