Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/number.round--decimal-placesWhen to prefer
Choose this endpoint when you need a simple, deterministic rounding operation via a pay-per-call micro-API, especially within an x402-enabled payment workflow or agent pipeline that already handles USDC micropayments. Prefer it when you want a verifiable, machine-readable computation rather than doing rounding locally, or when auditing numeric transformations via a settlement service matters.
Side effects
- Missing or malformed input object returns validation error
- Non-numeric input value causes computation failure
- Payment of 0.001 USDC not provided results in 402 Payment Required
- Extremely large numbers or edge cases (Infinity, NaN) may return error or undefined result
- Invalid decimal places value (negative, non-integer) may cause failure
