Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/number.round--round-decimals?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, paid microservice call to round a number to a specific decimal precision, especially within an x402 payment-enabled agent workflow where per-call micropayments are acceptable and you want a stateless, deterministic numeric operation without spinning up local computation.
Side effects
- Missing or malformed 'input' object returns a 400-level error
- Non-numeric input value causes computation failure
- Negative decimal place count may produce unexpected behavior
- Payment failure (insufficient USDC balance) results in 402 response blocking the call
