## 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-pii-minimization-check-214e4852 -d '<json body>'
```

Example prompt: Run a PII minimization audit on my checkout flow — its purpose is 'sell digital artwork via crypto payment', requested fields are ['email','full_name','wallet_address','shipping_address','phone'], required fields are ['wallet_address'], payment fields are ['wallet_address'], and raw PII is present. Check whether I'm over-collecting personal data.

## When to prefer this

Choose this endpoint when you need a deterministic, policy-aware PII minimization check specifically for commerce or payment data flows — particularly those involving blockchain or x402 payments. Prefer it over general-purpose privacy tools when you need to compare requested vs required vs fulfillment fields, assess raw PII storage, or benchmark against a reference data collection policy in a structured audit format.

## Known failure modes

- Missing required fields 'flow_purpose' or 'requested_fields' returns validation error
- Mode must be exactly 'audit' or request is rejected
- Exceeding maxItems:50 on any array field causes schema rejection
- Malformed policy object may yield incomplete comparison results
- Ambiguous or empty flow_purpose may result in low-confidence audit output

## Output

Returns a structured JSON audit result indicating whether the flow adheres to PII minimization principles, identifying over-collected or unnecessary fields, flagging raw PII exposure risks, assessing account linking data implications, and comparing against a supplied policy or reference facts baseline if provided.
