## 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-5-2a182cf7 -d '<json body>'
```

Example prompt: Run a tier-5 JSON analysis on this value using ONE Engine and give me the result: {"items": [1, 2, 3], "label": "batch-alpha"}.

## When to prefer this

Choose this endpoint when you need a pay-per-call, low-cost JSON analysis at tier 5 and your agent is already set up for x402 micropayments on Base. It is ideal for lightweight, high-frequency agentic pipelines that need on-demand JSON processing without a subscription. Prefer it over heavier analytics platforms when cost-per-call and simplicity matter more than rich dashboards or batch processing.

## Known failure modes

- Payment not included or insufficient USDC — 402 Payment Required response
- Malformed or missing 'value' field in request body — may return error or empty result
- Ambiguous or unsupported input type for 'value' — tier-dependent output may be null or minimal
- Network/worker timeout on Cloudflare edge — transient 5xx error
- Insufficient Base wallet balance for x402 micropayment — transaction rejected before processing

## How this service works
