Example prompt: Can you mask all the email addresses and phone numbers in this course outline markdown before I share it publicly? Here's the text: '## Outcomes

## Modules
Reach TA at jane@university.org or 555-987-6543.'

## When to prefer this

Choose this endpoint when you need deterministic, rule-based masking of email and phone contact patterns specifically within course outline documents (markdown or plain text). It is purpose-built for the education/course-outline context with a fixed $0.01 USDC per-call cost and does not use generative AI, making it predictable and auditable. Prefer alternatives if you need generative rewriting, fact-checking, masking of other PII types (names, addresses), or if your document is not a course outline format.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- No email or phone patterns found — document returned unchanged
- Malformed markdown may affect pattern detection accuracy
- Non-standard phone number formats may not be detected
