How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing a single field 'value' with the rounded numeric result, e.g. {"value": 12.35}.
Example use cases
Currency amount rounding for invoices
“I need to round 47.8963 to exactly 2 decimal places so I can display it as a dollar amount on an invoice.”
Rounding scientific measurement output
“Take this sensor reading of 0.000456789 and round it to 4 decimal places so I can log it cleanly.”
Rounding zero decimals for a whole number
“Round 99.7312 to 0 decimal places so I get just a whole number back.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/number/round?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs deterministic, server-side numeric rounding to a precise number of decimal places, especially in micropayment-friendly agentic pipelines already using the x402/Base payment protocol. Useful when you want a lightweight, pay-per-call utility rather than embedding rounding logic client-side.
Side effects
- Missing 'value' field returns a validation error
- 'digits' outside range 0–12 is rejected
- Non-numeric input for 'value' causes a parse error
- Network or payment failure returns a 402 or 5xx error
