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. The output reflects the input values in reversed order, optionally sliced by size and offset parameters.
Example use cases
Reverse a ranked leaderboard
“I have a leaderboard stored as an array from first to last place — can you reverse it so the last-place entry comes first? The array is ["Alice", "Bob", "Carol", "Dave", "Eve"].”
Flip a processing queue order
“I need to reverse the order of my task queue so the most recently added tasks run first. Here's the queue: ["task_001", "task_002", "task_003", "task_004", "task_005", "task_006"].”
Invert a time-series data log
“Can you reverse this chronological list of log entries so the most recent one appears first? The list has entries like ["2024-01-01", "2024-01-02", "2024-01-03", "2024-01-04"].”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/reverse/t3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, cheap, pay-per-call array reversal without spinning up compute infrastructure. Ideal for autonomous agents that occasionally need to flip ordered lists as part of a larger workflow, especially when already operating within the x402/Base micropayment ecosystem. At $0.001 USDC per call it is cost-effective for sporadic use.
Side effects
- Array exceeds 1000 items — request rejected
- Missing required 'values' field — validation error
- Payment failure via x402 — 402 response returned before processing
- Malformed JSON in request body — parse error
- Invalid offset or size integers causing out-of-bounds behavior
