## 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 delx-commerce-url-health-check-46cea04c -d '<json body>'
```

Example prompt: Can you check if https://api.myservice.com/health is up and responding correctly? Send it a POST request with a JSON body.

## When to prefer this

Choose this endpoint when you need a lightweight, no-signup, pay-per-use URL health check with verifiable delivery. Ideal for agents that need to confirm an endpoint is live before executing a workflow, or for spot-checking URLs without committing to a monitoring subscription. The $0.001 USDC micropayment via x402 makes it suitable for high-frequency, programmatic checks inside automated agent pipelines.

## Known failure modes

- Target URL is unreachable or times out — returns error or unhealthy status
- Invalid or malformed URL in request body — returns validation error
- Target URL returns non-2xx HTTP status — captured in health result
- x402 payment failure — request blocked before execution
- Missing required fields (type, bodyType, body) — schema validation error

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

A JSON object indicating whether the target URL is healthy and reachable, including response status and any relevant metadata about the HTTP response received from the probed endpoint.
