## 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 asterpay-erc-20-token-security-analyzer-59cab5dd
```

Example prompt: Can you run a security analysis on the ERC-20 token at address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and tell me what risks were found and what the security score is?

## When to prefer this

Use this endpoint when you need a quick, structured security assessment of an ERC-20 token contract, including risk flags, holder data, liquidity, and a composite security score. Prefer this over generic blockchain explorers when you need a machine-readable risk summary rather than raw on-chain data, or when building automated DeFi due diligence workflows that require a normalized score.

## Known failure modes

- Invalid or malformed contract address returns an error
- Non-ERC-20 contract address may return incomplete or no data
- Token with extremely low activity may have insufficient data for scoring
- Network errors or upstream blockchain data unavailability may cause timeouts
- Payment failure (insufficient USDC balance) prevents access to the endpoint

## How this service works

Security analysis for any ERC-20 token contract

## Output

Returns the token's name and symbol, a security score (0-100), a list of identified risk factors (e.g. 'No audit found', 'Centralized ownership'), the number of holders, and liquidity in USD for the given contract address.
