## 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 pennyrail-batch-utility-processor-5b0ae4e7 -d '<json body>'
```

Example prompt: Can you run this batch of utility operations through PennyRail — here's the input object with all the tasks bundled together, and go ahead and authorize the $0.01 USDC payment to process them.

## When to prefer this

Use this endpoint when you need to execute multiple utility operations in a single round-trip and want to pay per-call via the x402 micropayment protocol. It is preferable when minimizing API call overhead matters, or when your workflow already integrates USDC micropayments. Avoid if you need strongly typed schemas or predictable response structure, as the output is fully open-form.

## Known failure modes

- Payment not authorized or insufficient USDC balance — x402 payment rejected
- Malformed input object missing required 'input' field — 400 Bad Request
- Batch utility operation fails internally — may return partial results or error object
- Network or Vercel cold-start latency causing timeout
- Unsupported utility types in the batch payload — unrecognized operations silently skipped or errored

## How this service works
