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 stably sorted version of the input array. Equal elements maintain their original relative order. The response reflects any size and offset constraints applied to the result.
Example use cases
Sort leaderboard scores stably
“I have a list of player scores [42, 17, 99, 42, 55, 17] and I want them sorted in stable order — equal scores should keep their original relative positions. Can you sort this array for me?”
Order product catalog by price tier
“Sort this array of product prices [29.99, 9.99, 49.99, 9.99, 19.99] stably so I can display them in ascending order without shuffling items that share the same price.”
Rank items with comparison reference
“I need to stably sort this array ["banana","apple","cherry","apricot"] using [1,0,3,2] as a comparison ordering guide — please return the result with at most 4 items starting from offset 0.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/stable-sort/t5?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a guaranteed stable sort (preserving relative order of equal elements) on a JSON array of up to 1000 items, especially inside an autonomous agent workflow that can pay micro-fees via x402 on Base. Prefer over client-side sorting when computation must be offloaded, auditable, or paid-for as a utility step in a larger pipeline.
Side effects
- Array exceeds 1000-item limit — request rejected
- Invalid JSON array in 'values' field — parse error
- Payment failure via x402 on Base — 402 response, no computation performed
- Missing required 'values' field — validation error
- 'other' comparison array length mismatch — undefined behavior or error
