## 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 coinopselect-token-safety-api-abba0596
```

Example prompt: Before I buy this token, can you run a safety check on the contract 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 on Base and tell me the risk verdict and any flags?

## When to prefer this

Use this endpoint when an AI agent needs to programmatically assess the on-chain safety of an ERC-20 token before a trade, listing, or investment decision — especially on Base. It is particularly valuable in autonomous DeFi workflows where human review is not practical, and when you need a structured risk score plus specific flags rather than just a general description. Prefer this over manual block explorer lookups when you need a machine-readable verdict with confidence score.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Unsupported network value causes a validation error
- Token not yet indexed may return incomplete or no data
- Rate limit or payment failure via x402 blocks the request
- Cached results may be stale for recently deployed tokens

## How this service works

Paid on-chain token, wallet, contract and research data over x402 on Base.

## Output

A JSON object containing: a numeric safety score (0–100), a verdict string (e.g. 'low_risk', 'high_risk'), an array of risk flags, the token owner address, total supply, decimals, chain ID, network name, and a generatedAt timestamp. Also includes whether the result was served from cache.
