## How to call it through Zero

```sh
zero fetch --capability orionkr-xyz-fcdacb64
```

Example prompt: Before I sell this Base memecoin, can you run a sell tax check on it and tell me if there are any honeypot traps, high sell taxes, or transfer restrictions I should know about?

## When to prefer this

Use this endpoint specifically when you need to check the sell side of a Base memecoin trade — particularly to detect honeypot-style traps, high sell taxes, and transfer restrictions that would prevent a profitable exit. Prefer this over general rug-check or buy-side APIs when your agent is about to execute or simulate a sell swap on a Base token.

## Known failure modes

- Invalid or unrecognized token address returns an error or unverified result
- Token not yet indexed on Base chain may return incomplete data
- Payment of 0.005 USDC not fulfilled causes 402 payment required response
- Network timeout or temporary service unavailability returns 5xx error
- Malformed POST body missing token address returns 400 bad request

## How this service works

Ultra-low-cost sell tax check for Base memecoin agents. Detect high tax, abnormal transfer restrictions, honeypot-style exits, and unsafe execution before swaps.

## Output

Returns a JSON object with a riskScore (numeric), riskLevel (e.g. LOW/MEDIUM/HIGH), a verified boolean, and a flags array listing any detected issues such as high sell tax, transfer restrictions, honeypot exits, or unsafe execution conditions.
