# ONE Engine Number Analysis Pack Tier 5

> ONE Engine Number Analysis Pack Tier 5 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.0025/call, status unknown (last checked 2026-10-02).

Performs a tier-5 number analysis computation on a numeric input value, returning a tier-dependent analytical 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-number-analysis-pack-tier-5-46103527 -d '<json body>'
```

Example prompt: Run the ONE Engine tier-5 number analysis on the value 42 and tell me what result comes back.

## When to prefer this

Choose this endpoint when you need a low-cost, per-call numeric analysis at the tier-5 level using the ONE Engine analysis pack, particularly in agentic workflows that require pay-per-use micro-payment billing via x402 on Base. Prefer it when you need deterministic numeric evaluation without provisioning a full analytics service.

## Known failure modes

- Missing or non-numeric 'value' field causes validation error
- Payment failure or insufficient USDC balance blocks the call (x402 payment required)
- Malformed request body returns 400-level error
- Server-side computation failure returns 500-level error

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

A JSON object containing the tier level (5) and a tier-dependent analytical result for the submitted numeric value. The exact nature of the result varies by tier logic applied server-side.
