How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object with a single field 'value' containing the maximum of the two input numbers, e.g. {"value": 10}.
Example use cases
Agent decision threshold check
“I need to know which is larger: 512 or 349 — use ONE Engine to compare them and tell me the max.”
Dynamic pricing cap enforcement
“Compare the two price values 19.99 and 24.50 and tell me the higher one using ONE Engine.”
Score leaderboard tie-break
“I have two scores, 9750 and 9820 — which one is the maximum? Run the ONE Engine max check for me.”

Choose this endpoint when you need a lightweight, cheap ($0.0009 USDC), pay-per-call maximum computation for two numbers inside an autonomous agent workflow on Base, especially when you want to avoid spinning up local compute or when the x402 payment protocol is already integrated.
Side effects
- Missing or non-numeric input for 'a' or 'b' may result in an error or unexpected result
- Payment failure via x402 if insufficient USDC balance on Base
