## 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 chainward-address-risk-verdict-api-7724de5b
```

Example prompt: Before you send any USDC to 0xAbC...123 on Base, run a ChainWard check on it and tell me whether I should Pay, Hold, or treat it as Unknown — and give me the one reason behind the verdict.

## When to prefer this

Choose this endpoint when an AI agent needs a fast, per-call risk verdict before executing a payment to a Base or BNB Chain address — especially in autonomous payment workflows where the agent must decide Pay, Hold, or defer without human input. Ideal for agentic pipelines using x402 payment rails on Base, where a single authoritative reason and evidence trail are needed to justify or block a transfer. Prefer this over generic blockchain explorers when you need an actionable verdict rather than raw on-chain data.

## Known failure modes

- Address not found on Base or BNB Chain — returns Unknown verdict
- Malformed or invalid address format — request rejected without charge
- Network congestion causing delayed on-chain data lookup
- Address too new with insufficient on-chain history — Unknown verdict returned
- Payment failure via x402 — check not performed and no charge applied

## How this service works

Paste any Base or BNB Chain address before you pay or hire it. ChainWard tells you Pay or Hold, and why, from the wallet’s on-chain history. Free.

## Output

A JSON response containing a verdict of Pay, Hold, or Unknown along with a single primary reason, supporting evidence, and applicable limits. For seller addresses, includes a real vs. self-funded demand signal. For BNB Chain agent addresses, indicates whether the agent is externally hired or operating within its own circle. Failed checks are not charged.
