## 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 blockchain-money-map-agent-commerce-dispute-evidence-packager-e97818b1 -d '<json body>'
```

Example prompt: I need to package dispute evidence for a failed agent commerce transaction — the buyer claimed 'no output received', they paid 0.05 USDC, expected a 'sentiment analysis report', but the delivered_output_status shows 'timeout error'. Can you run a check with receipt hash sha256:aabbcc...1234 and artifact hash sha256:ddeeff...5678?

## When to prefer this

Choose this endpoint when an AI agent needs to formally package and evaluate dispute evidence for a failed or contested x402 micropayment transaction between agents. It is specifically designed for the x402 agent commerce protocol where structured evidence — including cryptographic hashes of receipts and artifacts — is needed for arbitration. Prefer this over generic logging or audit endpoints when the dispute involves a concrete buyer claim, a payment amount, and a delivery status that need to be compared side-by-side.

## Known failure modes

- Missing required fields (buyer_claim, paid_amount, expected_output, delivered_output_status) returns validation error
- Invalid receipt_hash or artifact_hash format (not matching sha256:[64 hex chars]) causes schema rejection
- mode field not set to 'check' returns unsupported mode error
- Malformed JSON body results in 400 bad request
- Payment not included or insufficient USDC triggers 402 Payment Required before processing
