Example prompt: What integer does the Roman numeral MCMXCIX represent? Convert it to a number for me.

## When to prefer this

Choose this endpoint when an agent needs a reliable, zero-signup, pay-per-result Roman numeral to integer conversion — especially in agentic pipelines processing historical texts, clock faces, structured documents, or user input where classical notation must be decoded programmatically.

## Known failure modes

- Invalid characters in input (non-Roman numeral characters) return a validation error
- Empty or missing 'roman' field results in a bad request response
- Malformed Roman numeral strings (e.g. 'IIII' vs 'IV') may be accepted or rejected depending on strictness
- Payment failure via x402 prevents the call from completing

## How this service works
