## 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-t1-d6a79b2a -d '<json body>'
```

Example prompt: Run a tier-1 JSON analysis on this value for me: {"score": 42, "label": "high"} — I need the structured analysis result back right away.

## When to prefer this

Choose this endpoint when you need ultra-low-cost ($0.0007 USDC), per-call JSON analysis within an autonomous agent workflow and are already set up to handle x402 micropayments on Base. It is ideal for high-frequency pipelines where cost per call matters and the tier-1 analysis output meets your needs.

## Known failure modes

- Payment not provided or insufficient USDC balance causes 402 Payment Required response
- Malformed or missing 'value' field in request body may return an error or empty result
- x402 payment settlement failure on Base network causes transaction rejection
- Cloudflare Worker timeout if submitted value is excessively large
- Ambiguous schema for 'value' may produce unexpected or minimal analysis output
