## 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 automaton-sovereign-token-approval-risk-api-ce2d5c3c
```

Example prompt: Before I sign this token approval, can you check the approval risk for this transaction and tell me if it looks safe or suspicious?

## When to prefer this

Use this endpoint when an agent or user needs a quick, pay-per-call risk signal on a token approval before signing a blockchain transaction, especially in DeFi workflows where smart contract drain attacks are a concern. Prefer this over general blockchain analytics tools when you need a focused approval-specific risk score via a lightweight GET request with micropayment access.

## Known failure modes

- Missing required query parameters returns an error or empty result
- Invalid token or approval data may return a null or indeterminate risk score
- Service unavailability or Cloudflare Workers timeout returns a 5xx error
- Payment not received (x402) results in a 402 Payment Required response before data is returned
