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, with elements in opposite order from the input. Optional size and offset parameters control how many elements are returned and where to start.
Example use cases
Reverse a ranked leaderboard
“I have a leaderboard array sorted best-to-worst and I need it flipped to worst-to-best: ["Alice", "Bob", "Carol", "Dave", "Eve"]. Can you reverse that list?”
Invert a processing queue
“Reverse this task queue array for me so the last items get processed first: ["task_001", "task_002", "task_003", "task_004"]”
Flip a timeline of events
“I have a list of historical events in chronological order and I want them reversed into reverse-chronological order: ["2020-01-01", "2021-06-15", "2022-03-10", "2023-11-22"]. Please reverse that array.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/reverse/t8?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple, pay-per-call array reversal without spinning up server infrastructure. Ideal for autonomous agents on Base that need lightweight utility operations at $0.01 per call via x402. Best when the array has at most 1000 items and you want a fast, stateless transformation.
Side effects
- Array exceeds 1000-item limit — request rejected
- Missing required 'values' field — validation error
- Payment failure via x402 — 402 response, no transformation performed
- Malformed JSON input — parse error returned
