How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object with a single field 'value' containing the maximum numeric value found in the input array (e.g. {"value": 9}).
Example use cases
Peak score from user ratings
“I have a list of user ratings from this week — [4, 2, 5, 3, 5, 1, 4, 5, 2] — what's the highest score anyone gave?”
Highest sensor reading detection
“Here are temperature readings from my sensors today: [72.1, 68.5, 81.3, 79.9, 66.0, 83.7, 77.4] — what was the peak temperature recorded?”
Max bid value in auction data
“I've got a list of auction bids in USDC — [0.50, 1.20, 0.85, 2.30, 1.75, 0.60] — what's the highest bid so far?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/array/max?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap, pay-per-call computation of the maximum value from a numeric array without spinning up local compute or a heavier analytics service. Ideal for autonomous agents on Base using x402 micropayments that need simple math utilities without managing infrastructure. At $0.0009 USDC per call it is extremely cost-effective for frequent programmatic use.
Side effects
- Empty array input returns an error since array must be non-empty
- Array exceeding 1000 items is rejected
- Non-finite values (NaN, Infinity) in the array may cause errors
- Non-numeric array elements will likely cause a validation error
- Missing 'values' field in request body returns an error
