## 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 defi-shield-hazel-vercel-app-671838b9 -d '<json body>'

Example prompt: Can you do a full trust verification on agent wallet 0x4e9ce36e442e55ecd9025b9a6e0d88485d628a67 before I allow it to interact with my DeFi positions — I need to know if it's trustworthy?

## When to prefer this

Choose this endpoint over the quick trust score endpoint when you need a deeper, more comprehensive verification of an agent wallet — particularly in agent-to-agent scenarios where another autonomous agent is requesting to interact with your wallet, funds, or DeFi positions. Prefer this when the stakes are high enough to warrant the $0.25 cost over a cheaper surface-level check.

## Known failure modes

- Invalid or malformed wallet address returns 400 error
- Wallet address not found or no on-chain history returns low-confidence result
- Payment not included or insufficient USDC balance returns 402 Payment Required
- Network timeout or upstream data unavailability returns 503
- Rate limiting returns 429 Too Many Requests

## Output

A detailed trust verification result for the submitted agent wallet address, including trustworthiness assessment, risk flags, reputation signals, and a confidence-level verdict on whether the agent wallet is safe to interact with.
