How this service works
Take the first N elements. Call when you cap agent payloads before paid calls. Returns items prefix 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 a JSON object containing the prefix sub-array of the first N elements from the input array, along with a count of how many items were returned.
Example use cases
Cap agent payload before paid API call
“I'm about to send this list of 200 records to a paid API but I only want to pass the first 25 — can you slice the array down to 25 items before I send it?”
Paginate large dataset for display
“I have a full results array from a search and I only want to show the first 5 items on the first page — take just those 5 from the front of this list.”
Limit recommendations list to top N
“My recommendation engine returned 50 items but I only want to surface the top 3 to the user — grab just the first 3 from this array.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/arr-takeWhen to prefer
Use this endpoint when you need a simple, stateless, key-free way to truncate a JSON array to its first N elements, especially before passing data to expensive or rate-limited downstream APIs. Prefer it over custom code when running in an agent context without a native runtime, or when you want a consistent, auditable array-slicing step in a workflow pipeline.
Side effects
- N exceeds array length — may return fewer items than requested or the full array
- N is zero or negative — may return empty array or error
- Input items is not a valid JSON array — validation error
- N is not an integer — type error
