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-sampled subset of the input array, with elements drawn at uniform intervals across the source array, respecting the requested size and offset.
Example use cases
Downsampling time-series data
“I have an array of 1000 sensor readings — can you pull out 50 evenly-spaced values so I can plot a lighter trend line?”
Pagination preview sampling
“Take this list of 600 user records and give me an even sample of 30 entries spread across the whole list, starting from the beginning.”
A/B test cohort selection
“From this array of 400 customer IDs, extract an evenly-distributed sample of 40 to assign to a test group.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/even-sample/t6?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, low-cost utility to uniformly downsample or subsample a JSON array without setting up local computation infrastructure. Ideal for agents that need quick, pay-per-call array sampling on Base via x402 payments, especially when the array is too large to process inline or when even distribution across the dataset matters.
Side effects
- Array exceeds 1000-item limit — request rejected
- Invalid or non-array value for 'values' field — schema validation error
- Payment not included or insufficient — 402 Payment Required response
- Requested sample size larger than input array — may return full array or error
- Offset beyond array bounds — may return empty result
