How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the reversed array — elements of the input array in reverse order, optionally sliced by offset and size parameters.
Example use cases
Reverse a ranked results list
“I have this ranked list of items ["gold","silver","bronze","honorable mention"] and I need it reversed so the lowest rank comes first — can you flip the order of the array?”
Reverse paginated data slice
“Take this array of 50 user records and reverse just 10 of them starting at offset 5, so I can display them in reverse chronological order on that page.”
Invert comparison array alignment
“I need to reverse this array [1,2,3,4,5,6,7,8,9,10] and compare it against [10,9,8,7,6,5,4,3,2,1] to check they match after flipping.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/reverse/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, cheap ($0.0005 USDC), pay-per-call array reversal with no setup or auth overhead, especially in an autonomous agent workflow using x402 payments on Base. Prefer it over custom code when you want a stateless, serverless utility call with optional slicing via offset and size.
Side effects
- Input array exceeds 1000 items — request rejected
- Missing required 'values' field — validation error
- Invalid JSON array format — parse error
- Payment not provided or insufficient USDC — 402 response
- Network timeout on the Cloudflare Workers edge
