How this service works
Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.
Output
Returns a JSON object containing the flattened (single-level) version of the input array, potentially with comparison results if an optional 'other' array was supplied.
Example use cases
Normalize API response arrays
“I got back a deeply nested array from another API — [["a","b"],["c",["d","e"]]] — can you flatten it into a single-level list so I can loop through the items?”
Prepare data for tabular processing
“I have a JSON array with up to 500 items nested several levels deep and I need it completely flat before I insert it into a table. Can you flatten [[1,[2,3]],[4,[5,[6,7]]]] for me?”
Compare flattened output to reference list
“Flatten my nested array [["foo",["bar","baz"]],"qux"] and compare it against my reference list ["foo","bar","baz","qux"] so I can see if they match.”

Endpoint
POSThttps://one-search.one-engine.workers.dev/v3/array/flatten/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call array flattening operation without spinning up a local compute environment — especially in autonomous agent pipelines on Base using x402 micropayments where you want predictable, low-cost ($0.0005 USDC) data normalization at the edge.
Side effects
- Input array exceeds 1000 items — request rejected
- Malformed or non-array 'values' field — validation error
- Payment not included or insufficient — 402 Payment Required response
- Network timeout on the Cloudflare Worker edge
- Invalid 'offset' or 'size' parameter types causing schema rejection
