## 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 delx-commerce-refund-policy-preflight-f92cfa9b -d '<json body>'
```

Example prompt: Can you check whether this purchase — order ID #8821, bought 3 days ago, unused, within the 30-day return window — qualifies for a refund under our standard policy that requires items to be unused and returned within 30 days?

## When to prefer this

Use this endpoint when you need a lightweight, no-signup, pay-per-call preflight check to evaluate refund eligibility before committing to a full refund transaction. Ideal for AI agents managing customer support flows, e-commerce automation, or marketplace enforcement where you want a verifiable, policy-driven decision without building custom logic. Prefer this over custom rule engines when the policy can be expressed as a JSON object and you need instant, per-request pricing via USDC on Base or Solana.

## Known failure modes

- Malformed policy JSON results in a validation error response
- Missing required purchase fields cause incomplete eligibility evaluation
- Ambiguous policy rules may result in false negatives or positives
- Policy and purchase objects with incompatible schemas may cause processing errors
- Network or payment failure returns a 402 or 5xx error before evaluation occurs
