## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability one-engine-array-drop-first-5-items-tier-7-8931bd60 -d '<json body>'
```

Example prompt: Take this array and drop the first 5 items from it, then return what's left along with the rich tier-7 diagnostic breakdown: [10, 20, 30, 40, 50, 60, 70, 80, 90, 100].

## When to prefer this

Choose this endpoint when you need a straightforward, pay-per-call utility to strip the first 5 items from an array and want the richer tier-7 diagnostic output for debugging or auditing purposes. It is ideal for autonomous agents running on tight budgets ($0.0025 per call) that need deterministic array slicing with detailed introspection, especially when integrated into x402-compatible payment flows on Base.

## Known failure modes

- Array has fewer than 5 elements — may return an empty array or an error indicating insufficient items
- Invalid or non-array input body — returns a 400 bad request error
- Payment not included or insufficient — returns HTTP 402 Payment Required
- Network timeout on the Workers.dev edge — transient 5xx error
- Malformed JSON body — returns parse error

## How this service works

Drop the first 5 array items. Tier 7/10 returns progressively richer diagnostics.

## Output

Returns the input array with the first 5 elements removed (i.e., elements from index 5 onward), along with tier-7 progressively richer diagnostic metadata including details about the operation, dropped items count, remaining count, and additional debug/tracing information.
