How this service works
Return every 3th array item. Tier 1/10 adds richer diagnostics.
Output
Returns a new array containing only the elements at positions 0, 3, 6, 9, … (every 3rd element) of the input array, along with Tier 1 richer diagnostic metadata such as original array length, output length, step size, and processing details.
Example use cases
Downsample time-series sensor data
“I've got a long array of temperature readings taken every second and I only need every 3rd one to reduce the volume — filter it down and show me the diagnostic output.”
Extract every third product from a catalog
“Here's an array of 90 product IDs from our inventory list. Pull out every 3rd item so I can build a rotating spotlight feature, and include the step diagnostics.”
Thin a log array for quick review
“I have an array of 300 log entries and I want a quick sample — give me every 3rd entry from the list along with any diagnostic info about how the step was applied.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v6/array-step/every-3/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, cheap, pay-per-call array downsampling operation — specifically extracting every 3rd element — without standing up any custom infrastructure. The Tier 1 variant is preferable when you want diagnostic metadata about the operation in addition to the filtered result. At $0.0008 per call it is cost-effective for agents that need lightweight list-thinning repeatedly.
Side effects
- Empty array input returns empty result or error
- Non-array body causes a 400 bad request
- Payment not provided or insufficient funds triggers x402 payment-required response
- Malformed JSON body results in parse error
- Array contains non-serializable types which may cause processing failure
