Chunk Arrays for Agents
x402
Chunk Arrays for Agents is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).
Splits a JSON array into fixed-size chunks to support batching, pagination, and payload-limit compliance

How this service works
Chunk a JSON array. Use to batch tool calls, page results, or stay under payload limits. Returns array chunks with the requested size (bounded input). $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
Output
An array of sub-arrays, each containing at most chunk_size items from the original input. The final chunk may be smaller if the total item count is not evenly divisible. Response is deterministic first-party JSON with no extra metadata.
Example use cases
Batch API calls across large dataset
“I have an array of 3000 user IDs and need to call a downstream API that only accepts 50 at a time — can you chunk the array into groups of 50 for me?”
Paginate results for display
“Take these 200 search results and break them into pages of 10 items each so I can show them one page at a time to the user.”
Parallel task queue partitioning
“I need to distribute this list of 120 tasks across 4 workers — split the array into chunks of 30 so each worker gets an equal share.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/list-chunkWhen to prefer
Choose this endpoint when your agent pipeline needs to batch tool calls, enforce pagination, or stay under downstream payload limits without implementing array-splitting logic in your own code. It is deterministic, requires no API key or subscription, costs $0.001 USDC per call via x402 on Base, and returns no side effects — ideal for lightweight preprocessing steps in agentic workflows.
Side effects
- items array exceeds 10,000 item cap — request rejected with a structured validation error (not billed)
- chunk_size less than 1 — validation error returned
- missing or malformed items field — structured validation error
- payment not provided or insufficient — x402 payment required response
