## 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 china-sourcing-payment-red-flags-checker-d5578baf -d '<json body>'
```

Example prompt: Before I wire the 50% deposit to Shenzhen Brightway Electronics Co., can you check for payment red flags — the payee on the contract is Guangzhou Trading Hub Ltd, account number CN8932017654?

## When to prefer this

Use this endpoint specifically when you need a fast, structured GO/NO_GO payment risk verdict for a Chinese supplier before funds move — especially when you suspect payee name vs account holder mismatches, unusually high deposit ratios, or contract party discrepancies. Prefer it over a general supplier audit when the primary concern is the payment step itself rather than factory legitimacy or product certification.

## Known failure modes

- Missing required fields (payee_name or deposit_ratio) returns a validation error
- Deposit ratio outside 0-1 range may produce unreliable scoring
- Ambiguous or very short payee names may yield low-confidence flags
- No network connectivity to the worker returns a 5xx error
- Edge cases with blank contract_party may skip mismatch checks

## Output

Returns an array of specific payment red flags detected (e.g. payee mismatch, excessive deposit ratio, unverifiable account), a GO/NO_GO/CAUTION verdict indicating whether it is safe to proceed with payment, and a list of safe payment rules the buyer should follow to protect themselves.
