How this service works
Return first 16 array items. Tier 1/10 adds richer diagnostics.
Output
A JSON response containing up to 16 elements taken from the start of the submitted array, plus Tier 1 diagnostic metadata such as total input length, slice boundaries, and structural information about the extracted subset.
Example use cases
Preview large dataset head
“I've got a huge JSON array of product records — can you grab just the first 16 items so I can preview what the data looks like before processing the whole thing?”
Debug array pipeline output
“My data pipeline is producing a big array and I want to inspect the first 16 elements along with any diagnostic info to make sure the structure looks right.”
Paginate agent memory efficiently
“I have an array of 200 stored memories and I only want to feed the first 16 into the next step of my agent workflow — can you slice just the head of the list?”
Technical details
Endpoint
POSThttps://one-search.one-engine.workers.dev/v6/array-head/items-16/t1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a deterministic, cheap, stateless head-slice of exactly 16 items from an array — especially when you also want lightweight diagnostic metadata (Tier 1) about the operation. It is ideal for agent workflows that need to preview, paginate, or sample the leading elements of a list without processing the full dataset. Prefer it over generic slicing logic when you want a pay-per-call micro-utility with audit diagnostics baked in.
Side effects
- Empty array input returns an empty result set
- Malformed JSON body causes a 400 parse error
- Array with fewer than 16 items returns all available items (no error)
- Payment failure or missing x402 header results in a 402 Payment Required response
- Oversized payload may trigger request size limits
