## 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 chainverdict-token-verification-api-5f45deff
```

Example prompt: Can you verify whether the token at contract address 0x1f9840a85d5af5bf1d1762f925bdaddc4201f984 is legitimate and safe — I want to know if ChainVerdict flags any issues with it before I buy.

## When to prefer this

Use ChainVerdict when you need a quick, pay-per-call on-chain token safety verdict without committing to a subscription. It is well suited for agents that sporadically verify tokens before trading, listing, or investing, and want to pay only for what they use via x402 micropayments.

## Known failure modes

- HTTP 402 returned if payment is not included — requires x402 v2 payment of $0.005 USDC per call
- Invalid or unrecognized token address returns an error or empty result
- Malformed contract address format may cause a bad request error
- Token not indexed or unknown symbol may return no verdict data

## How this service works

x402 v2 pay-per-call. Unpaid requests receive HTTP 402 with payment requirements.

## Output

Returns a verdict or analysis object for the specified token, including safety assessment, risk flags, and other on-chain verification data relevant to the token's legitimacy and trustworthiness.
