## 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 token-safety-verdict-api-base-chain-b8e0129d
```

Example prompt: Can you check whether this Base chain token at address 0x1234abcd...5678 is safe to buy — give me the safety score and verdict?

## When to prefer this

Use this endpoint when you need a quick, scored safety verdict for a specific token on the Base chain before a trade or investment decision. It combines GoPlus security signals with DexScreener liquidity data under fixed published rules, giving a transparent, reproducible verdict rather than a raw data dump. Prefer it over manually querying GoPlus or DexScreener separately when you need a single composite score and verdict in one call.

## Known failure modes

- Invalid or malformed contract address returns an error
- Token not found on Base chain returns no data or error
- GoPlus or DexScreener upstream unavailability causes service failure
- Non-Base chain addresses submitted to this endpoint will not return valid results

## How this service works

Is this token safe? Score 0-100 and verdict safe/caution/danger with reasons and source URLs, from GoPlus token security + DexScreener liquidity using fixed published rules. Chains: base, ethereum, bsc, arbitrum, solana. 10-min cache. $0.02.

## Output

Returns a numeric safety score from 0 to 100, a categorical verdict (safe, caution, or danger), a list of human-readable reasons explaining the verdict, and source URLs from GoPlus token security data and DexScreener liquidity data. Results are cached for 10 minutes.
