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 rotated array, with elements cyclically shifted by the specified offset. The array wraps around so elements shifted past the end reappear at the beginning.
Example use cases
Circular buffer rotation for scheduling
“I have a list of 8 workers ["Alice","Bob","Carol","Dan","Eve","Frank","Grace","Hank"] and I want to rotate the duty schedule by 2 positions so the next person in line is first — can you do that?”
Sliding window data realignment
“I have a sensor readings array [10,20,30,40,50,60,70,80,90,100] and need to shift it left by 4 positions to realign it with a reference timestamp — please rotate it by offset 4.”
Round-robin playlist rotation
“Rotate my playlist queue ["Song A","Song B","Song C","Song D","Song E"] by 1 position so the next song becomes first, using the array rotate utility.”
