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 as they appeared in the input.
Example use cases
Sort leaderboard scores for display
“I have a list of game scores [1500, 200, 4800, 200, 900] — can you stable sort them so ties stay in their original order for the leaderboard?”
Order product prices for ranking
“Sort these product prices [29.99, 9.99, 49.99, 9.99, 19.99] in ascending order, keeping duplicate prices in the order they appeared.”
Arrange numeric IDs for processing
“I need to process these IDs in sorted order: [1042, 37, 512, 37, 888, 100] — stable sort them so duplicate IDs maintain their original sequence.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/stable-sort/t8?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 via a lightweight pay-per-call API, especially in agentic workflows on Base where x402 micropayments are already supported. Prefer it over building your own sort when you want deterministic, server-side computation without managing infrastructure.
Side effects
- Input array exceeds 1000 items — request rejected
- Invalid or non-array values field — schema validation error
- Payment not provided or insufficient USDC — 402 payment required
- Malformed JSON body — 400 bad request
- Network timeout on Cloudflare Worker — 5xx error
