How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing a tier field (value: 9) and a result field with the tier-9-processed packed set output derived from combining arrays A and B.
Example use cases
Deduplicating tag lists across datasets
“I have two lists of tags from different sources — ["news","sports","tech"] and ["tech","finance","sports"] — can you pack them into a unified set so I can remove duplicates?”
Merging permission sets for access control
“Pack these two permission arrays together into a set: ["read","write"] and ["write","execute","delete"], so I can see the combined unique permissions.”
Combining product category arrays
“I've got two product category arrays from my catalog — ["shoes","bags","hats"] and ["bags","jackets","scarves"] — please pack them into a single set result.”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v2/array-set-pack/t9?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-cost ($0.01 USDC), pay-per-call set-packing operation on two arrays within an autonomous agent pipeline running on Base/x402. Ideal for agentic workflows that need lightweight, on-demand array set operations without standing up custom infrastructure. Prefer this over general-purpose code execution when you want a metered, trustless utility call with crypto micropayment settlement.
Side effects
- Missing or non-array inputs for 'a' or 'b' fields returns a validation error
- Payment failure via x402 on Base results in a 402 response blocking execution
- Empty arrays may return an empty or trivial result depending on tier logic
- Malformed JSON body returns a 400 bad request error
- Network or worker timeout may return a 5xx error on the Cloudflare edge
