## 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-json-analysis-pack-tier-9-a8e442f9 -d '<json body>'
```

Example prompt: Run the ONE Engine tier-9 JSON analysis pack on this value: {"userId": 42, "status": "active"} and give me the structured result.

## When to prefer this

Choose this endpoint when you need to run ONE Engine's tier-9 JSON analysis specifically — for example, when a workflow requires the highest or a specific tier of analysis output, and you are operating in an x402-enabled agent environment on Base where micropayment-gated utility APIs are acceptable.

## Known failure modes

- Missing or malformed 'value' field in request body may return an error or unexpected result
- Payment failure via x402 protocol will block the call from executing
- Tier-dependent output may be opaque or undocumented, making result interpretation difficult
- Network errors on the Cloudflare Workers edge may cause transient failures

## How this service works

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

## Output

Returns a JSON object containing a 'tier' field set to 9 and a 'result' field whose content is tier-dependent — the specific analysis output varies based on the tier-9 logic applied to the submitted value.
