Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 orionkr-xyz-9ba3e69b
```

Example prompt: Before I sign this token approval for the DEX swap on Base, run an approval risk check — I want to know if the spender is dangerous, if the approval amount is unlimited, and whether there's a router mismatch or any unsafe execution conditions.

## When to prefer this

Use this endpoint when an agent is about to sign a token approval or execute a swap on Base and needs a fast, cheap ($0.005) pre-signing safety gate. Prefer this over generic rug-check endpoints when the specific concern is approval-level risk: unlimited approvals, spender identity, router mismatches, and do-not-execute conditions rather than token liquidity or rug-pull analysis.

## Known failure modes

- Invalid or missing approval transaction data returns 400 bad request
- Unrecognized spender address may return empty flags with LOW risk rather than an error
- Network timeout or service unavailability returns 5xx
- Insufficient USDC payment via x402 returns 402 payment required
- Malformed Base address input returns validation error

## How this service works

Ultra-low-cost approval risk check for Base agents before signing token approvals or swaps. Detects dangerous spender approval, unlimited approval risk, approval-to-router mismatch, unsafe execution, transaction safety issues, and do-not-execute conditions.

## Output

Returns a JSON object with a list of risk flags (e.g. dangerous spender, unlimited approval, router mismatch, unsafe execution), a verified boolean, a riskLevel string (LOW/MEDIUM/HIGH), and a numeric riskScore (0-100).
