## 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 httpay-defi-health-check-a738df3b -d '<json body>'

Example prompt: Give me a quick overall health check of the DeFi ecosystem right now — I want to know if things look stable or if there are any red flags across major protocols.

## When to prefer this

Use this endpoint when you need a broad, single-call snapshot of overall DeFi ecosystem health without needing per-protocol granularity. Ideal for dashboards, risk monitoring agents, or daily briefings where a top-level DeFi status is sufficient. Priced at $0.02 USDC per call with no API key required, making it suitable for pay-as-you-go agent workflows on Base.

## Known failure modes

- Payment not received or insufficient USDC — returns 402 Payment Required
- Upstream data source unavailable — may return partial or stale data
- Network congestion on Base causing payment confirmation delays
- Invalid x402 payment header format — returns 400 Bad Request
