## 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-t9-number-analysis-0412e7f4 -d '<json body>'
```

Example prompt: Run a T9 number analysis on the value 42 using the ONE Engine number analysis pack and tell me the tier and result it returns.

## When to prefer this

Choose this endpoint when you need lightweight, low-cost ($0.01 USDC) numeric tier classification at the T9 level via a pay-per-call model on Base, particularly in autonomous agent pipelines that need per-value analysis without committing to a subscription.

## Known failure modes

- Missing or non-numeric 'value' field causes validation error
- Payment failure via x402 results in 402 response and no analysis returned
- Invalid or malformed request body returns a 4xx error
- Service unavailability on Cloudflare Workers returns 503

## 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 9 in this endpoint context) and a 'result' field whose content depends on the tier — representing the analytical output for the submitted numeric value.
