How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
A JSON object containing the top-10 unique values extracted from the input array, with optional deduplication against a provided comparison array and support for pagination via offset.
Example use cases
Deduplicate survey response tags
“I collected 800 survey responses and each one has a category tag — can you deduplicate that list and give me the top 10 most distinct tags?”
Find unique items not in reference list
“I have a big array of user-submitted keywords and a reference list of known ones — can you find the top 10 unique keywords that aren't already in my reference list?”
Paginate unique values from log data
“I've got an array of 1000 log event types and I want to page through the unique ones — give me the top 10 unique event types starting from offset 20.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/unique/t10?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap, pay-per-call deduplication and top-N extraction on a JSON array without standing up your own data pipeline. Ideal for autonomous agents processing moderate-sized lists (up to 1000 items) that need unique value extraction in real time, especially when comparing against a second array to filter already-known values.
Side effects
- Array exceeds 1000-item limit — request rejected
- Malformed JSON array input — validation error
- Missing required 'values' field — 400 Bad Request
- Payment not included or insufficient — 402 Payment Required
- Offset out of bounds — empty or partial result set
