How this service works
Convert numbers to Roman numerals (1–3999) and Roman numerals back to numbers, with strict validation that rejects non-standard forms like IIIM or VX. Use this when an agent needs to numbers ↔ Roman numerals, with validation.
Output

Example use cases
Year formatted as Roman numerals
“What is the year 1999 written in Roman numerals?”
Decode a Roman numeral inscription
“I found the inscription MCMXLVIII on a building — what year does that correspond to?”
Validate and convert a Roman numeral
“Is IIIM a valid Roman numeral? If so, what number does it represent?”

Endpoint

Choose this endpoint when you need strict, standards-compliant Roman numeral conversion with validation — especially useful when user input may be malformed or non-standard and you need clear rejection of invalid forms rather than silent best-guess parsing.
Side effects
- Input integer out of range (below 1 or above 3999) returns validation error
- Non-standard Roman numeral form (e.g. IIIM, VX) is rejected with a validation error
- Malformed or non-numeric input string returns a parsing error
- Missing required 'value' query parameter returns a 400 error
- Missing or invalid 'op' parameter may default or error depending on service behavior
