# Hermes x402 Smart Contract Verdict

> Hermes x402 Smart Contract Verdict is a paid API for AI agents from api.zlovev.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-02).

Returns a one-call rule-based exposure score and verdict for a smart contract or ERC-20 token, aggregating on-chain facts about ownership, proxy status, pause capability, bytecode selectors, and source verification.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 hermes-x402-smart-contract-verdict-19e7b5d1
```

Example prompt: Can you run a contract verdict on 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base and tell me the exposure score, whether ownership is renounced, and any risky capabilities like minting or blacklisting?

## When to prefer this

Choose this endpoint when you need a fast, single-call risk verdict on a smart contract or ERC-20 token with weighted scoring across multiple risk dimensions — ownership, proxy, pause, bytecode capabilities, and source verification — without having to manually call separate ABI, source, and token-security endpoints and combine results yourself. It is ideal for pre-trade screening, portfolio monitoring, or user-facing risk alerts in DeFi agents. Prefer alternatives if you need a full security audit, raw ABI, or granular on-chain transaction history rather than a synthesized verdict.

## Known failure modes

- Invalid or non-checksummed address returns 400 with validation error
- Address not a contract (EOA wallet) may return is_contract: false with limited facts
- Unsupported chain value returns 400 enum error
- Unverified contract source reduces confidence level to 'partial' with missing fields listed
- Network congestion or RPC failure may cause 503 or timeout
- Same idempotency key with different address/chain combination returns error or ignores key

## How this service works

Pay-per-call data API for AI agents. No API key, no account, no signup — pay USDC on Base (eip155:8453) per request; free /api/meta lists all 24 endpoints. One call each: web page to LLM-ready text and link previews; China A-share quotes and limit-up pool; Chinese text and pinyin; Base/Ethereum on-chain reads (address, token, ERC-20 balances, tx, blocks, transfer history, gas price in USD); NFT records (collection, owner, and ipfs:// tokenURI resolved through public gateways); full-page screenshots; email verification without sending mail; ENS forward/reverse resolution; smart-contract due diligence (ABI, verified source, proxy); token security facts (owner, renounced ownership, paused, bytecode capability selectors); domain dossier (RDAP, DNS, TLS certificate, HTTP facts, hosting network); a one-call rule-based contract verdict (published-weights exposure score, owner/pause/proxy/capability facts, every reason with evidence); and an ERC-20 allowance risk check that returns the live allowance matrix for one wallet across up to 10 spenders (unlimited flags, contract/EOA status, exact revoke calls) with a single verdict.

## Output

Returns a JSON object with: ok flag, block number, chain, contract address, a facts object (owner, paused, symbol, is_erc20, verified, renounced, is_contract, is_proxy_like, signal_counts by severity), an array of scored reasons with codes, detail strings, and weights, a verdict object (band like 'low'/'elevated'/'high', label, numeric score 0-100, headline string), a confidence object (level, missing fields if any), and a disclaimer noting this is rule-based, not an audit.
