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 elements drawn from the input array, respecting the requested size and offset, with optional comparison results if a second array was provided.
Example use cases
Downsample time-series data for chart
“I have 800 temperature readings from the past month and I need exactly 50 evenly spaced ones to plot on a chart — can you sample them for me?”
Compare two arrays by even sampling
“I have two arrays of 300 product prices each — take an even sample of 30 from the first one and compare it against this second reference array to see how they line up.”
Paginated preview of large dataset
“I have a list of 1000 user IDs and want to show a representative preview of 10 of them, evenly spread, starting after the first 50 — can you pull that subset?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/even-sample/t8?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, evenly spaced subsample of an array (e.g. for charting, downsampling, or representative previews) and want a pay-per-call model with no subscription. Prefer it over manual slicing logic when you also want optional side-by-side comparison with a second array.
Side effects
- Input array exceeds 1000 items — request rejected
- Invalid or missing 'values' field — validation error
- Size or offset parameters out of range — unexpected or empty result
- Malformed JSON array input — parse error
- Payment failure via x402 — 402 response, no result returned
