> EVM Address Risk Check is a paid API for AI agents from agent-exec.448c.org, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-11).

Checks an EVM wallet address for risk signals, returning a verdict, numeric score, reasons, and data sources — paid per-call via x402 with no account required.

## 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 evm-address-risk-check-71803241 -d '<json body>'
```

Example prompt: Can you check whether the Ethereum address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE is safe to interact with — give me a risk verdict and score on Base?

## When to prefer this

Choose this endpoint when you need a fast, accountless, pay-per-use risk verdict on an EVM address without setting up API credentials — ideal for AI agents operating autonomously with a crypto wallet. Prefer over traditional compliance APIs when you want x402 micropayment settlement and no account provisioning overhead. Best for Base or Ethereum addresses; not suitable for non-EVM chains.

## Known failure modes

- Invalid or malformed 0x address returns an error
- Unsupported chain value causes rejection
- Insufficient payment balance causes HTTP 402 with no result
- Address not found in any source returns low-confidence result with empty reasons
- Network congestion may delay payment settlement and response

## How this service works

Accountless, pay-per-use code execution for software agents: submit source code, get stdout, stderr and exit code back from an isolated, network-less sandbox. No account, no API key -- possession of valid payment is sufficient.

## Output

Returns a JSON object with: a string verdict (e.g. 'low risk', 'high risk'), a numeric risk score, an array of human-readable reasons explaining the verdict, an array of data sources consulted, a disclaimer string, and a payment sub-object confirming the USDC charge with payer, amount, network, and on-chain transaction hash.
