Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/number.roman--roman-to-integerWhen to prefer
Choose this endpoint when you need a quick, pay-per-use Roman numeral to integer conversion without setting up your own parsing logic, especially in agent pipelines where micro-payments via x402/USDC are already supported and convenience over cost matters.
Side effects
- Invalid or non-Roman-numeral input may return an error or unexpected result
- Payment failure (402) if USDC balance is insufficient for the $0.001 per-call fee
- Malformed request body missing the required 'input' field will result in a validation error
- Edge cases like zero or very large Roman numeral strings may not be supported
