# Grey Ridge Signals — Token Security Analyzer (Base)

> Grey Ridge Signals — Token Security Analyzer (Base) is a paid API for AI agents from x402-data-api.sigrunner.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-16).

Returns a comprehensive security analysis of any ERC-20 token contract on Base mainnet, including risk flags, proxy details, ownership info, capabilities, and a honeypot simulation result.

## 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 grey-ridge-signals-token-security-analyzer-base-17d1bb55
```

Example prompt: Can you run a security check on the USDC token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — I want to know the risk score, any red flags like blacklisting or minting powers, and whether ownership has been renounced?

## When to prefer this

Choose this endpoint when you need a rapid, on-demand security audit of any ERC-20 token on Base mainnet without API key setup. It is ideal for agents performing pre-trade due diligence, DeFi risk screening, or portfolio analysis pipelines. It is pay-per-call ($0.02 USDC) via x402, requiring no signup, making it well-suited for automated or infrequent lookups. Prefer alternatives if you need multi-chain support or deeper bytecode-level auditing.

## Known failure modes

- Invalid or malformed token address returns an error — must be a valid 0x-prefixed 20-byte hex address
- Token not deployed on Base mainnet returns no contract data
- Honeypot simulation may return 'unavailable' if storage slot layout is non-standard
- Payment failure via x402 protocol results in 402 response with no data
- Rate limiting or worker timeout may return a 5xx error for complex contracts

## How this service works

Token security / honeypot detector for a Base mainnet ERC-20: EIP-1967/1822 proxy + upgradeability detection, bytecode dispatcher scan for mint/pause/blacklist/fee-setter/ownership selectors, owner() renouncement check, and a live eth_call state-override simulation testing whether a synthetic wallet can actually transfer() the token. Returns risk_score (0-100) + verdict (clear/review/block) + human-readable flags.

## Output

A JSON object containing: token metadata (name, symbol, decimals, total supply), chain identifier, a list of human-readable risk flags, proxy details (is_proxy, admin address, implementation address, upgradeability), ownership info (owner address, type, renounced status), token capabilities (can_mint, can_burn, can_pause, has_blacklist, etc.), a honeypot simulation result with transferability status, an overall risk_score (0–100), a verdict string ('review', 'safe', 'risky'), and a timestamp of analysis.
