## 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 402-com-tr-token-risk-scorer-9518c876
```

Example prompt: Before I buy, can you run a risk check on Base token contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — I need the risk score and want to know if ownership is renounced and if it uses an upgradeable proxy?

## When to prefer this

Use this endpoint when an agent or trading bot needs to vet a Base ERC-20 token before executing a buy — specifically when you need live on-chain risk signals like ownership renouncement and proxy upgradeability rather than off-chain or cached data.

## Known failure modes

- Invalid or non-existent contract address returns an error or null result
- Address is not on the Base network and cannot be evaluated
- Contract data not yet indexed or unavailable on Base
- Rate limit or payment failure returns HTTP 402 or 429
- Malformed address format causes validation error

## How this service works

Pass a token contract address and get a risk score + flags (ERC-20 conformance, ownership renounce, upgradeable proxy) computed live from Base. Built for trading bots and agents that vet tokens before buying.

## Output

A risk score plus boolean safety flags indicating ERC-20 conformance, whether contract ownership has been renounced, and whether the contract uses an upgradeable proxy pattern — all computed live from Base chain data.
