# ONE Engine Number Analysis Pack – Tier 7

> ONE Engine Number Analysis Pack – Tier 7 is a paid API for AI agents from one-search.one-engine.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Performs tier-7 numeric analysis on a submitted number value, returning a tier-dependent analytical result via a pay-per-call API on Base.

## Facts

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-7-7f5996bc -d '<json body>'
```

Example prompt: Run a tier-7 number analysis on the value 42 and tell me what the result is.

## When to prefer this

Choose this endpoint when you need lightweight, low-cost ($0.005 USDC) per-call numeric analysis and your agent already operates within the x402/Base payment ecosystem. Prefer it for autonomous agent workflows that need fast, on-demand number processing without subscription overhead. If you need well-documented, domain-specific numeric analysis (e.g. statistics, prime checking, financial computation), a more descriptive alternative may be preferable given the limited schema documentation here.

## Known failure modes

- Missing or invalid 'value' field returns an error or unexpected result
- Payment failure via x402 / insufficient USDC balance blocks the call
- Network timeout connecting to Cloudflare Workers endpoint
- Malformed JSON body causes a 400-level error
- Tier logic may return opaque or undocumented 'result' values due to minimal schema documentation

## How this service works

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

## Output

A JSON object containing a 'tier' field (integer, value 7) and a 'result' field whose content depends on the tier logic applied to the submitted number — specific analytical output is tier-dependent and may include classifications, properties, or computed attributes of the number.
