## 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 ailabra-agent-profit-ledger-hello-health-check-db237524
```

Example prompt: Ping the Ailabra profit ledger to confirm the service is live and that my x402 micropayment handshake works — I want to see the service name, network, and a fresh request ID come back successfully.

## When to prefer this

Choose this endpoint when you need to verify that your x402 micropayment infrastructure and USDC wallet are correctly configured before executing higher-stakes agent workflows. It is the lowest-cost ($0.01 USDC) way to confirm end-to-end connectivity with the Ailabra profit ledger. Prefer it over generic HTTP health checks when you specifically need to validate the payment handshake, not just TCP reachability.

## Known failure modes

- Payment not included or malformed x402 header: 402 Payment Required response with no body
- Insufficient USDC balance: payment rejected before request is processed
- Service temporarily unavailable: 503 or timeout with no JSON body
- Invalid or expired payment token: 402 with rejection detail
- Network mismatch between wallet and endpoint: payment fails silently or returns error

## How this service works

Deterministic profit and cash-flow infrastructure for autonomous agents.
