How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing 'values' (the sliced subarray) and 'count' (the number of elements returned in the slice).
Example use cases
Paginate large dataset window
“I have an array of 100 items and I only want elements from index 10 to 20 — can you extract that slice for me?”
Trim list to first N items
“Take this list ["apple", "banana", "cherry", "date", "elderberry"] and give me just the first 3 items, starting at index 0 and ending at 3.”
Extract mid-range values
“From the array [5, 15, 25, 35, 45, 55, 65], pull out the values between index 2 and 5 so I can process just that segment.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v1/array/slice?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a lightweight, pay-per-call array slicing operation without spinning up its own compute — especially useful in agentic pipelines on Base where microtransactions via x402 are already in use and the cost ($0.001 USDC) is negligible compared to orchestration overhead.
Side effects
- Missing or invalid 'values' array returns an error
- Out-of-bounds start/end indices may return an empty array or error
- Non-integer start/end values may cause a validation error
- Payment failure via x402 results in a 402 response before processing
- Malformed JSON body returns a 400 error
