# ONE Engine Rotate Array Right (Parameter 1, Tier 7)

> ONE Engine Rotate Array Right (Parameter 1, Tier 7) is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-11).

Rotates a JSON array one position to the right deterministically and returns enriched Tier 7 diagnostics alongside the result.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-rotate-array-right-parameter-1-tier-7-a80540ca -d '<json body>'
```

Example prompt: Take this array [1, 2, 3, 4, 5] and rotate it one position to the right — I want the Tier 7 diagnostic details included in the result.

## When to prefer this

Choose this endpoint when you need a deterministic right-rotation of a JSON array by exactly one position and want richer Tier 7 diagnostics for auditing or debugging. It is ideal for autonomous agents that need verifiable, reproducible array transformations with detailed processing metadata rather than a bare result. Prefer this over lower-tier variants when diagnostic transparency matters.

## Known failure modes

- Invalid or malformed JSON array input returns a 400 error
- Empty array input may return an unmodified result or error
- Payment failure via x402 returns 402 Payment Required
- Non-array JSON types (object, string, number) are rejected
- Oversized arrays may hit payload size limits

## How this service works

Deterministic JSON array processing utility: Rotate array right; parameter=1. Tier 7/10 provides progressively richer diagnostics.

## Output

Returns the input JSON array with all elements shifted one position to the right (last element wraps to the first position), along with Tier 7 progressive diagnostics including processing metadata, transformation details, and enriched debugging information.
