## What it does

Verdix address risk gives an AI agent a pre-transfer check for EVM addresses on Base. The server returns `safe`, `caution`, or `danger` with the reasons behind the result. Its checks cover sanctions, scam and phishing lists, address-poisoning lookalikes, contract age and provenance, and burn addresses.

The server exposes quick, standard, deep, and lite checks plus `get_pricing`. Each paid call uses x402 and USDC from your Base wallet. `VERDIX_MAX_PRICE_USD` sets the per-call ceiling, while the private key remains local. Lite never returns `safe`, so that verdict requires another tier.

You need Node.js 18 or newer and a separate Base wallet with a small USDC balance. Paid tools cannot sign a payment without `VERDIX_PRIVATE_KEY`.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `VERDIX_PRIVATE_KEY`, `VERDIX_MAX_PRICE_USD` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- check a Base address before sending USDC
- catch address-poisoning lookalikes
- halt a transfer after a `danger` verdict
- screen a contract before approving it
- read the current check prices

## Example prompts
- Check `0x...` on Base before sending funds and stop if the result is `danger`.
- Run the `quick` check for the recipient address and show the risk reasons.
- Call `get_pricing`, then check the address with the `standard` tier.
