## 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-1-d484126b -d '<json body>'
```

Example prompt: Run a number analysis on the value 42 and tell me what the tier-1 results say about it.

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost per-call numeric analysis utility, especially in autonomous agent workflows that support x402 micropayments on Base. Ideal when you need a fast computation on a single number without setting up a heavier analytics service.

## Known failure modes

- Missing or non-numeric 'value' field returns validation error
- Payment failure via x402 results in 402 Payment Required response
- Invalid JSON body causes 400 Bad Request
- Service unavailability on Cloudflare Workers returns 503
- Tier-1 output may be opaque or minimally described if the result schema is underdocumented
