## 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-7-46eb73e0 -d '<json body>'
```

Example prompt: Run a tier-7 JSON analysis on this value using ONE Engine: {"user": "alice", "score": 42}.

## When to prefer this

Choose this endpoint when you need a low-cost ($0.005 USDC), pay-per-call JSON analysis utility that integrates natively with the x402 micropayment protocol on Base and returns a tier-7 structured result — ideal for autonomous agents that process many small payloads without a subscription.

## Known failure modes

- Payment failure: x402 payment not accepted or insufficient USDC balance on Base
- Invalid input: missing or malformed 'value' field in request body
- Upstream worker error: Cloudflare Worker returns 5xx if internal processing fails
- Empty result: tier-dependent logic produces no output for certain input types
- Rate limiting: excessive calls may be throttled by the worker

## How this service works

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

## Output

Returns a JSON object with a 'tier' field (integer, value 7) and a 'result' field whose content depends on the tier-specific logic applied to the submitted value.
