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 8, indicating the processing tier used) and a 'result' field with the tier-dependent packed output derived from the two input arrays.
Example use cases
Deduplicating merged tag lists
“I have two lists of tags from different sources — ["sports", "news", "tech"] and ["tech", "finance", "news"] — can you pack them together using the ONE Engine array set-pack to get a clean combined result?”
Finding common elements in agent pipelines
“Take these two arrays of user IDs my agent collected — [101, 202, 303] and [202, 303, 404] — and run them through the ONE Engine set-pack so I can see the processed combined output.”
Combining feature flag sets
“I've got two sets of feature flags from different environments: ["flag_a", "flag_b"] and ["flag_b", "flag_c", "flag_d"]. Pack them together using the ONE Engine array set-pack utility and tell me the result.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v2/array-set-pack/t8?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call array set-pack computation without provisioning infrastructure, especially in autonomous agent workflows on Base using x402 micropayments. Ideal when you need a quick, deterministic tier-8 transformation of two arrays at very low cost ($0.0075 USDC).
Side effects
- Missing or malformed 'a' or 'b' array fields returns an error response
- Payment failure via x402 on Base results in a 402 Payment Required response
- Empty arrays may return a trivial or empty packed result
- Non-array types passed as 'a' or 'b' may cause a schema validation error
- Cloudflare Worker timeout on very large arrays
