## 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 nohumans-directory-listing-verdict-abee9da9
```

Example prompt: Before my agent pays for that listing 9a8bf56d-2fc, pull the nohumans.directory verdict on it — I want to know if it's pay, caution, or avoid and what the reasons are.

## When to prefer this

Use this endpoint when an AI agent needs to make a trust decision about a specific nohumans.directory listing before spending money on it. It is ideal for automated pre-spend gating in agentic workflows, especially when integrating unknown or newly discovered x402 API listings. Prefer this over manual research when you need a structured, machine-readable verdict with explicit reasons derived from real probe history and payment delivery outcomes.

## Known failure modes

- Listing ID not found — returns an error or empty result for unknown UUIDs
- Insufficient probe history — verdict may be 'caution' due to lack of data rather than confirmed issues
- Stale probe data — verdict may not reflect very recent changes in listing behavior
- Network or payment errors — the endpoint itself costs $0.005 USDC via x402 so failed payment results in no response

## Output
