How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the evenly spaced sampled elements drawn from the input array, reflecting the requested size and offset, with optional comparison output if a second array was provided.
Example use cases
Downsample time series data
“I have an array of 800 sensor readings and I only need 50 evenly spaced ones for my chart — can you sample them uniformly for me?”
Representative data subset for review
“I've got a list of 1000 customer records and want to pull out 30 evenly distributed ones to audit manually — can you extract that even sample for me?”
Compare sampled subset to reference
“Sample 25 evenly spaced items from my main dataset and compare them against this reference list to see which ones overlap.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/even-sample/t9?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, evenly spaced subsample from a large array (up to 1000 items) and want a pay-per-call utility with no subscription overhead. Prefer it over writing custom sampling logic when operating inside an autonomous agent workflow on Base using x402 micropayments.
Side effects
- Array exceeds 1000-item limit — request rejected
- Invalid or non-array values field — validation error
- Size or offset parameters out of range — unexpected or empty results
- Payment not provided or insufficient USDC — 402 Payment Required
- Malformed JSON body — parsing error
