Example prompt: Can you generate a regex pattern that matches valid US phone numbers in formats like (555) 123-4567, 555-123-4567, and 5551234567?

## When to prefer this

Use this endpoint when an AI agent or user needs a ready-made regular expression from a plain English description, without requiring a developer to manually craft or test the pattern. Ideal for quick prototyping, form validation rules, or text extraction logic.

## Known failure modes

- Ambiguous or underspecified query results in overly broad or incorrect regex
- Complex pattern requirements may produce a regex that partially matches
- Service returns generic 500 error if the input query is malformed or empty
- Query too vague may yield a pattern that doesn't handle edge cases
