How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns an object containing the stably-sorted version of the input array, preserving the relative order of elements that compare as equal. May also include metadata about the sort operation.
Example use cases
Ranking leaderboard scores stably
“I have a leaderboard with 200 player scores that need to be sorted from highest to lowest — players with the same score should keep their original relative order. Can you stable-sort this array of scores for me?”
Sorting paginated product listings
“Sort this batch of 50 product prices in ascending order starting from offset 100 in my full dataset, so I can display the next page of results correctly.”
Multi-key stable sort with comparison array
“I need to sort this list of item IDs ["z3","a1","m7","a1","b2"] using this priority comparison array [1,3,2,4,5] as the sort key, keeping equal elements in their original order.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/stable-sort/t6?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a guaranteed stable sort (preserving original order of equal elements) on arrays up to 1000 items, especially when using a secondary comparison array. Prefer it for pay-per-call, serverless agent workflows on Base using x402 where you want minimal overhead and no subscription.
