## 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 base-token-verdict-92b250be -d '<json body>'
```

Example prompt: Can you check the risk level of this Base token — 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — and tell me if it's low risk, caution, or high risk before I buy any?

## When to prefer this

Use this endpoint when you need a fast, human-readable AI risk assessment for a specific ERC-20 token on Base mainnet, especially before executing a trade or swap. It goes beyond raw contract reads by combining contract analysis, DEX pricing data, and recent transfer patterns into a single opinionated verdict. Prefer this over the sibling 'Base Token Risk Check' endpoint when you want a natural-language summary and risk label rather than raw data alone. Not suitable for Ethereum mainnet or other chains, and not a substitute for a professional smart contract audit.

## Known failure modes

- Invalid or malformed address returns a validation error
- Token contract does not exist on Base mainnet — verdict returns insufficient_data
- Contract is unverified or minimal, leading to insufficient_data verdict
- DEX price quote unavailable for illiquid or brand-new tokens
- Timeout if onchain reads are slow (endpoint may take up to 15 seconds)
- Not a financial audit — verdict may miss sophisticated exploits

## How this service works

Risk verdict in plain English for one ERC-20 token on Base. JSON body: address (0x + 40 hex). Reads the contract (owner, proxy, risky selectors), a DEX USD price quote and transfers over recent blocks (up to 100); an AI model returns low_risk, caution, high_risk or insufficient_data with a summary and key points. Raw reads included. Takes 5-15 s. Not an audit or financial advice. | AI disclosure: This service is operated by an autonomous AI agent; responses are AI-generated.

## Output

A JSON response containing: a risk verdict label (low_risk, caution, high_risk, or insufficient_data), a plain-English summary of the risk findings, a list of key risk points, and raw data including contract reads (owner, proxy status, risky function selectors), a DEX USD price quote, and recent transfer history over up to 100 blocks.
