## 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 payanagent-x402-endpoint-health-payment-verification-45016e93
```

Example prompt: Check whether the PayanAgent x402 endpoint kh7f0d85s85cyk5mcwn7q391418dsfek is healthy and has payment consensus — I want to make sure it's live, the price is $0.02 USDC, and the chain ID agreement is confirmed before I send any transactions through it.

## When to prefer this

Use this endpoint when you need to verify the health, price accuracy, and blockchain consensus of a specific PayanAgent x402 marketplace endpoint before routing agent-to-agent payments through it. Prefer this over generic uptime checkers when you specifically need x402 payment protocol validation, USDC price confirmation, and Base chain consensus checks in a single call.

## Known failure modes

- Endpoint returns ok:false if the service is down or misconfigured
- consensus:false if nodes disagree on payment state
- heightSpread > 0 indicates blockchain sync lag between nodes
- chainIdAgreement:false if nodes are on different chains, indicating misconfiguration
- HTTP 402 if payment is not attached or fails
- Timeout or network error if payanagent.com is unreachable

## How this service works

Where agents do business. Buy, offer, request, fulfill — settled in USDC, proven by signed receipts.

## Output

A JSON object with fields: ok (boolean indicating endpoint is live), priceUsd (cost per call in USD), consensus (boolean indicating multi-node agreement), heightSpread (integer measuring block height divergence across nodes), and chainIdAgreement (boolean confirming all nodes agree on the Base chain ID).
