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 array, preserving the relative order of equal elements from the original input. The response schema is open (additionalProperties: true), so it may include metadata alongside the sorted result.
Example use cases
Sort leaderboard scores stably
“I have a list of player scores [120, 85, 120, 200, 85, 75] and I need them sorted from lowest to highest, keeping the original order of ties intact — can you stable-sort this array for me?”
Order product prices for display
“Sort this array of product prices [29.99, 9.99, 49.99, 9.99, 19.99] in ascending order using a stable sort so that identical prices stay in their original sequence.”
Stable sort strings alphabetically
“I need to sort this list of names ["Zara", "Alice", "Bob", "Alice", "Charlie"] alphabetically using a stable sort — duplicates should keep their original order.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/stable-sort/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a reliable, pay-per-call stable sort for arrays of up to 1000 items without spinning up your own compute, especially in autonomous agent workflows on Base using x402 micropayments. Prefer this over client-side sorting when the sort must be auditable, reproducible, or when the agent environment lacks native sort utilities.
Side effects
- Array exceeds 1000 items — request rejected or truncated
- Invalid or non-array values field — validation error
- Payment failure via x402 on Base — 402 response before processing
- Malformed JSON body — parse error returned
- Empty required 'values' field — missing required parameter error
