How this service works
JSON Array Flatten One: JSON Array Flatten One flattens exactly one nesting level from a JSON array from bounded caller-supplied values without an external provider. Call JSON Array Flatten One before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Flatten One as versioned deterministic JSON. Price: $0.001 USDC via…
Output
Returns a JSON object with the flattened array under 'result.items', the count of resulting items in 'result.count', a status of 'pass', an operation label 'data_batch:json_array_flatten_one', and an evidence block confirming no data retention, no external calls, and a SHA-256 hash of the input.
Example use cases
Normalize paginated API results
“I fetched multiple pages of results and now I have an array of arrays like [[item1,item2],[item3,item4]] — can you flatten it one level so I have a single list I can iterate over?”
Unwrap grouped batch payloads
“My pipeline produced grouped chunks like [[a,b,c],[d,e,f]] and I need to collapse them into one flat array before I POST them — flatten it one level for me.”
Prepare nested category items for processing
“I have category items stored as nested lists, each category is its own sub-array inside a parent array. Flatten it one level so all the items are in a single list I can process one by one.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-array-flatten-oneWhen to prefer
Choose this endpoint when you need exactly one level of array nesting removed — not a full recursive deep-flatten. Ideal when your agent accumulates paginated or chunked results as an array-of-arrays and needs a flat list for downstream iteration, batch POSTing, or mapping. Prefer this over recursive flatten endpoints when preserving sub-arrays nested two or more levels deep is important.
Side effects
- Array exceeds 256-item limit — request rejected
- Input 'items' field missing or not an array — validation error
- Malformed JSON body — parse error
- Already-flat array passed in — returns same array unchanged (not an error but may not be useful)
