## 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 saylor-innovations-evm-scam-address-checker-c6bb2b18
```

Example prompt: Can you check if the address 0x4e5b2e1dc63f6b91cb6cd759936495434c7e972f is on the ScamSniffer scam or phishing blacklist?

## When to prefer this

Use this endpoint when you need to quickly screen an EVM wallet or contract address against the ScamSniffer phishing and wallet-drainer blacklist before authorizing a transaction, interacting with a contract, or accepting funds. Prefer this over generic on-chain data tools when the specific goal is fraud/phishing detection via a curated blacklist rather than general wallet analytics. It is also suitable for automated pre-transaction safety checks in agent workflows where a binary flagged/not-flagged signal plus a verdict is sufficient.

## Known failure modes

- Missing or malformed address parameter returns a validation error
- Non-EVM addresses (e.g. Solana or Bitcoin) may not be supported and could return an error or empty result
- ScamSniffer data source unavailable returns sources_failed array with errors
- Address not found on blacklist returns flagged=false but does not guarantee safety
- Rate limiting or payment failure may result in HTTP 402 or 429 responses

## How this service works

Check an EVM address against the ScamSniffer blacklist of wallet drainer, phishing and scam addresses and report whether it is flagged and the list size

## Output

Returns a JSON object indicating whether the queried EVM address is flagged on the ScamSniffer blacklist, along with a verdict string, the total size of the blacklist, the data source name, the timestamp of when the data was fetched, and optional security assessment details including a security score and summary.
