## 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`):

```

Example prompt: Compare our return processing cost per case before and after our new returns policy: before we had labour cost £100, postage £50, other costs £20, and processed 10 returns; after it's labour £110, postage £55, other costs £22, and we processed 11 returns.

## When to prefer this

Ideal for one-off operational reviews or reporting.

## Known failure modes

- processed_returns set to zero (excluded by exclusiveMinimum constraint — will fail validation)
- missing required fields (labour_cost, postage_cost, other_cost, or processed_returns) in either before or after object
- cost values exceed maximum threshold (1,000,000,000,000)
- payment not attached or insufficient USDC amount
- malformed JSON body
