Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 blockchain-money-map-x402-tool-confirmation-prompt-auditor-64a6a1ef -d '<json body>'
```

Example prompt: Audit my x402 tool called 'GetWalletBalance' — the prompt text says 'This will query your wallet balance for $0.01 USDC', price label is '$0.01 USDC', scope summary is 'read-only wallet balance lookup', confirmation_required is true — compare it against the reference facts and tell me if the prompt is compliant.

## When to prefer this

Use this endpoint when you need to programmatically verify that an AI agent tool's user-facing payment confirmation prompt meets transparency and compliance standards before deploying or listing the tool — especially when building x402-payment-gated tools and needing automated quality gates on prompt text, price disclosure, scope clarity, and buyer consent flows.

## Known failure modes

- Missing required facts fields (tool_name, prompt_text, price_label, scope_summary, confirmation_required_present) returns validation error
- Mode not set to 'audit' causes rejection
- Mismatched data types for boolean fields (consequence_text_present, buyer_cancel_option_present) cause schema error
- Payment not provided (x402) results in 402 Payment Required response
- Oversized string fields exceeding 500-character limit cause rejection
