## 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 joe-evm-token-screener-3056467e
```

Example prompt: Can you run a full token diligence screen on the contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base (chain ID 8453) and tell me the verdict and any stage failures?

## When to prefer this

Use this endpoint when you need a detailed, multi-stage diligence breakdown with a final verdict for a specific EVM token contract — particularly when you want to understand which individual screening stages pass or fail, not just a binary yes/no. Prefer this over the sibling joe-evm-token-viability endpoint when you need full audit detail rather than a quick heuristic GO/SOFT_NO/HARD_NO signal.

## Known failure modes

- Invalid or checksumless contract address returns an error
- Unsupported chain ID results in a coverage error or HARD_NO verdict
- Unverified or honeypot contracts may return a FAIL verdict with limited stage detail
- Network or RPC errors may cause incomplete stage results
- Coverage limits mean a PASS verdict does not guarantee safety — only that checked stages passed

## How this service works

Deterministic multi-stage EVM token diligence (verdict + stage summary). Not financial advice; coverage limits ≠ pass.

## Output

Returns a structured diligence verdict (e.g. PASS, FAIL, or similar) along with a per-stage summary detailing which checks passed or failed across multiple screening dimensions such as contract verification, liquidity, ownership, and other EVM-specific risk factors.
