How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing a 'tier' field (value 5) and a 'result' field with the tier-5-processed packed set output derived from the two input arrays.
Example use cases
Deduplicating merged tag lists
“I have two lists of tags from different sources — ["AI","tech","cloud"] and ["cloud","data","ML"] — can you pack them into a single deduplicated set using ONE Engine's array set pack?”
Combining user permission arrays
“I need to merge two permission arrays for a user: ["read","write"] and ["write","execute"] — use the ONE Engine array-set-pack to get the packed combined set.”
Set-packing two inventory lists
“Pack these two inventory ID arrays together into a set: array A is [101,102,103] and array B is [103,104,105] — run it through the ONE Engine set pack utility.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v2/array-set-pack/t5?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call array set packing computation with minimal overhead, especially in autonomous agent pipelines that use the x402 payment protocol on Base. Ideal when you want to combine or pack two arrays into a set structure without standing up your own compute.
Side effects
- Missing or non-array input for 'a' or 'b' fields — likely returns a 4xx validation error
- Payment failure via x402 protocol — request rejected before processing
- Empty arrays passed — may return an empty or trivial result
- Network/worker timeout — Cloudflare Worker may return 5xx under load
