## 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-get-nested-json-990b34a8 -d '<json body>'
```

Example prompt: Can you retrieve the nested JSON data from the PennyRail resource node — I'll authorize the $0.001 USDC micropayment — and return whatever structured data it gives back?

## When to prefer this

Choose this endpoint when you need to retrieve nested JSON data from the PennyRail settlement network and are willing to pay a $0.001 USDC micropayment per call via the x402 protocol. Prefer this over free alternatives when the data is gated behind a PennyRail resource node specifically, or when you are building an agent workflow that already integrates x402 micropayment flows.

## Known failure modes

- Payment failure or insufficient USDC balance results in 402 Payment Required
- Malformed or missing 'input' object in request body returns 400 Bad Request
- Node unavailable or Vercel cold-start timeout returns 503 or 504
- Empty or null nested JSON response if the resource node has no data configured
- Schema mismatch if caller omits the required 'input' wrapper object

## How this service works

Machine-readable settlement service

## Output

Returns an open-ended JSON object (additionalProperties: true) containing whatever nested data the resource node holds — structure varies by node configuration but is always machine-readable JSON.
