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, produced by flipping the order of elements from the input values array, optionally constrained by offset and size parameters.
Example use cases
Reverse paginated result order
“I have a list of search results in this order: ["result1", "result2", "result3", "result4", "result5"] — can you reverse them so the last result appears first?”
Flip a ranked leaderboard
“Reverse this leaderboard array so the lowest-ranked player appears first: ["Alice", "Bob", "Carol", "Dave"]”
Invert a sequence for processing
“I need to process this queue in reverse order: [10, 20, 30, 40, 50, 60] — can you flip it starting at offset 2, limiting to 4 items?”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/reverse/t2?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, cheap, pay-per-call array reversal without spinning up compute infrastructure. At $0.0007 USDC per call via x402 on Base, it is ideal for autonomous agents that need occasional array transformations without maintaining persistent services or API keys.
