How this service works
Flatten one level of nested lists. Call when you normalize agent-held nested arrays before mapping. Returns flattened items and count for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns the flattened array (one nesting level removed) and an integer count of the resulting items. No data is retained server-side.
Example use cases
Normalize nested API response arrays
“I got back a JSON response where results are grouped in nested arrays like [[a,b],[c,d]] — can you flatten it one level so I can map over a single list?”
Prepare batched agent task queue
“My agent queued tasks in nested groups like [[task1,task2],[task3]] — flatten it one level so I can process them in order.”
Flatten grouped tag lists before dedup
“I have tags organized in nested lists by category like [[python,js],[react,node]] — flatten them one level so I can deduplicate across all of them.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/flatten1?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, stateless, single-level array flatten without writing custom logic — especially in agent pipelines where you want a reliable micro-utility for normalizing nested JSON arrays before downstream mapping, deduplication, or iteration. Not suited for deep/recursive flattening.
Side effects
- Input 'items' field is missing or not an array — likely 400 error
- Items contains non-array elements at the top level — behavior may skip or error on non-list entries
- Payment not provided or invalid — 402 Payment Required response
- Deeply nested arrays are only partially flattened (only one level removed by design)
