Example prompt

Technical details
Endpoint
GEThttps://orionkr.xyz/v1/base/pre-sign-safety?utm_source=zero.xyzWhen to prefer
Use this endpoint immediately before signing any swap, token approval, or memecoin transaction on Base when you need a fast, cheap ($0.005 USDC) risk gate. Prefer this over general token-scan endpoints when you have a specific pending transaction to evaluate rather than a token address lookup.
Side effects
- Invalid or missing transaction data returns an error
- Unsupported chain or token address returns validation error
- Payment not included or insufficient USDC triggers 402 Payment Required
- Malformed request body returns 400 Bad Request
- Timeout if transaction data is too complex to score in time
