How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the tier level (4) and the tier-dependent packed result of the two input arrays, representing the computed set-pack output.
Example use cases
Deduplicating tag lists from two sources
“I have two lists of content tags — one from our CMS and one from our analytics tool — can you pack them together and remove duplicates? CMS tags are ['sports','news','politics'] and analytics tags are ['news','tech','sports','health'].”
Merging product SKU sets for inventory
“Pack these two SKU arrays from our warehouse and storefront systems together: warehouse has ['SKU-001','SKU-002','SKU-003'] and storefront has ['SKU-002','SKU-004','SKU-005'] — I need the combined packed set.”
Combining user permission sets
“I need to pack together two permission arrays for a user — their base permissions are ['read','write'] and their role permissions are ['write','delete','admin'] — merge them into one packed set.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v2/array-set-pack/t4?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a low-cost, pay-per-call set-pack operation on two arrays without provisioning any infrastructure. It is ideal for autonomous agents running on Base that require lightweight array manipulation at tier-4 quality with micro-payment billing via x402.
Side effects
- Missing array inputs 'a' or 'b' returns a validation error
- Payment failure or insufficient USDC balance returns 402 status
- Empty arrays may produce an empty or trivial packed result
- Malformed array types (non-array values) likely cause a 400 error
- Network or worker timeout may occur under load
